Kyliotic:

==Json metadata for the extension==

Hey, @[[User:Kyliotic|Kyliotic]] I noticed you were experimenting with adding metadata to pages for use with the extension. I just wanted to make sure you are aware that the plan is to add either the [[mediawikiwiki:Extension:Semantic_MediaWiki|Semantic mediawiki]] or [[mediawikiwiki:Extension:Cargo|Cargo]] extension to achieve this easily in the future. [[User:Kostas|Kostas]] ([[User talk:Kostas|talk]]) 23:03, 2 March 2025 (UTC)

:Btw, a better way to test would probably be to use your own user page in order to not pollute the history of the page. [[User:Kostas|Kostas]] ([[User talk:Kostas|talk]]) 23:28, 2 March 2025 (UTC)

@[[User:Kostas|Kostas]],
Hopefully, this works. Captcha is so broken.
Oh is that so? I was going to keep it simple and just hide JSON data within the article.
And then a browser extension can just <code>getElementsByClassName()</code> and retrieve any needed data.
Also, your phrasing implies that there already is a browser extension, is that true? [[User:Kyliotic|Kyliotic]] ([[User talk:Kyliotic|talk]]) 23:28, 2 March 2025 (UTC)

:@[[User:Kyliotic|Kyliotic]] For some reason it did not but I saw your comments on the bug report page. That page should probably be moved as the Consumer Action Taskforce namespace is protected as a whole... Though that is the right place for such page.Anyway:
:* Captcha is broken with discussion tools. That is a known bug with the extensions and I am not sure when it will be fixed, hopefully we tune the confirmed/autoconfirmed user process to allow people to skip them as soon as possible.
:* The <nowiki><br></nowiki> tags are restricted purspose this has to do with what bots like to use to spam on the wiki. This will likely not change.
:On the extension conversation:
:* Hidden fields like you describe is what the cargo extension would basically provide but it would allow querring by field and using SQL syntax.
:* Yes work on the extension has started here https://github.com/WayneKeenan/ClintonCAT coordinating with the devs there would probably be for the best. I am sure they would be open to discussing this.
:There is some conversation on a thred on the on-topic chanell on the discord server as well.
: [[Consumer_Action_Taskforce:Talk_page_guidelines| The talk page guidelines might help with the captcha issues in the meantime]] [[User:Kostas|Kostas]] ([[User talk:Kostas|talk]]) 21:16, 3 March 2025 (UTC)

@[[User:Kostas|Kostas]],
Interesting info. I have to manually edit the discussion source in order to reply. Perhaps that also breaks notifications/pings. Cargo might be helpful with metadata read/write, but I have never used it.
:*So far, with simple embedded JSON, my extension can already look up if a website URL has been added to a wiki lookup table/database, and if is, it pulls embedded JSON from the wiki's product/organization articles. I just need to make GUI and then the basic concept is functional.
:*I only glanced at the ClintonCAT GitHub and it seems to actually read/search through all the wiki articles. To me, that seems like overkill. Having machine-readable metadata is so much more efficient and conveniant and sure, maybe Cargo may help with that.
:*But also, in my opinion, the nice thing about having the metadata embedded in the article source is that anyone may edit and fix metadata (once a proper format is established of course). So when someone creates a new article, someone can easily copy/paste a metadata template, edit it, and have the changes update live to the extension.
:*Maybe even some automation to automatically generate extension metadata (likely only possible with a MediaWiki extension)
:*Does Cargo achieve those points? I genuinely don't know, but just some things to consider.

Brother DCP-L3550CDW aftermarket toner failure

| Title = Brother DCP-L3550CDW Printer Scanner
| Release Year = 2018
| Product Type = Hardware Printer/Scanner

The [[Brother Industries, Ltd.|'''Brother''']] DCP-L3550CDW printer requires toner cartridges with embedded chips for authentication. Some '''aftermarket (non-OEM) cartridges''' include '''battery-powered chips''', which can lead to recognition failures if the battery depletes. However, '''genuine Brother cartridges do not contain a battery''', and the battery issue is not caused by the printer itself.

==Issue Description==
Aftermarket toner manufacturers use '''battery-powered chips''' to bypass Brother’s authentication system. When the '''1.5V battery inside these third-party chips depletes''', the printer fails to recognize the cartridge, displaying a misleading "No Toner" error message, even if toner remains in the cartridge.

This issue '''does not affect OEM Brother cartridges''', as they use '''a different chip design that does not require a battery'''. Brother’s chip system is primarily used for '''tracking toner levels and verifying cartridge authenticity''', which can restrict third-party toner compatibility but is not responsible for battery failures in non-OEM cartridges.<ref name="printerforums1" />

==User-Discovered Solutions==
Users have found several workarounds for this issue:

*Taking out the cartridges before turning off the printer for an extended period.
*Replacing the chip of the affected cartridge with the chip from an older cartridge that still has battery power ''(the chip is attached with screws)''.
*Replacing the 1.5V battery yourself if you have the necessary tools (requires soldering skills).
*Keeping the printer perpetually turned on to avoid battery depletion.

Users on Printer Forums reported success with '''replacing the battery or swapping the chip''' from a recognized cartridge.<ref name="printerforums2" /> Others have noted that pressing the '''red X and back arrow on the printer control panel''' allows access to toner status and may temporarily resolve the issue.<ref name="printerforums3" />

==Firmware-Related Issues==
Firmware updates have been linked to preventing the use of third-party toner chips. Several users reported that after updating their printer to '''firmware version 1.59''', previously working third-party cartridges were no longer recognized, triggering the "No Toner" error.<ref name="printerforums1" /> This is '''separate''' from the issue of dead batteries on aftermarket cartridges.

To prevent firmware-related cartridge recognition problems, users have suggested:
*Disabling automatic firmware updates via the printer settings.<ref name="printerforums2" />
*Blocking the printer from internet access to avoid automatic updates.<ref name="printerforums3" />

==Consumer Impact Summary==
While Brother's chip-based authentication system '''restricts the use of non-OEM toner cartridges''', the '''battery issue is caused by third-party cartridge manufacturers, not Brother'''. The chip requirement itself can be seen as a method to enforce '''a closed ecosystem''', potentially increasing costs for consumers. However, the '''battery-powered chip design is an independent choice made by aftermarket manufacturers''', not a function of the Brother printer or its OEM cartridges.<ref name="printerforums2" />

==Related Incidents==
This issue primarily affects '''aftermarket toner cartridges''' used in multiple Brother printer models:

*Brother MFC-L3770CDW experiences identical battery-related toner recognition failures.<ref name="printerforums2" />
*Users of Brother printers with TN-760 cartridges have reported similar issues.<ref name="printerforums1" />

One user on Printer Forums expressed frustration, stating: <blockquote>''"I am very close to trashing my Brother printer and getting something else. Are there any laser printers that DO NOT HAVE BATTERIES in their toner cartridges and have aftermarket cartridge sources?"''<ref name="printerforums3" /></blockquote>

The [[Brother Industries, Ltd.|'''Brother''']] DCP-L3550CDW printer experiences cartridge failures related to the 1.5V batteries that power the toner chip. If the printer is turned off for a prolonged period, these batteries can deplete, which results in the printer not recognizing the cartridge despite still being able to read its toner capacity.

==Issue Description==

When the battery depletes, the printer displays an error message that misleadingly tells users to replace the cartridge rather than identifying the actual battery issue. This occurs even when the toner level screen shows plenty of remaining toner, creating an artificial need to purchase new cartridges. The battery is not easy to access and is not designed to be replaced by users.[[File:Toner life screen.jpg|thumb|left|Toner life despite error screen]]

==User-Discovered Solutions==

Users have found several workarounds for this issue:

*Taking out the cartridges before turning off the printer for an extended period
*Replacing the chip of the affected cartridge with the chip from an older cartridge that still has battery power ''(the chip is attached with screws)''
*Replacing the 1.5V battery yourself if you have the necessary tools (requires soldering skills)
*Keeping the printer perpetually turned on to avoid battery depletion

According to users on Reddit<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/</ref>, removing all toner cartridges before restarting the printer & then reinserting them sometimes fixes the issue temporarily. As one user who provides managed print services noted: <blockquote>''I have confirmed 100% the printers themselves often short out the chips on toners. Aftermarket or OEM, when printer is rebooted or loses power. Remove all toners when restarting, then put them back in.''<ref>[https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/]</ref></blockquote>

==Battery Replacement Process==

As documented on the Ambor blog<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref> for the similar Brother MFC-L3770CDW model:

1. Take out the toner cartridge

2. Locate the chip contacts and slide the chip out by gently pressing to one side

3. Identify the small watch battery (marked as LR521/AG0, a 1.5V battery)

4. Using a paperclip, carefully push out the old battery

5. Replace with a new battery, keeping track of which side is positive (+ side down in most cases)

6. Reinsert the chip into the cartridge

7. Power cycle the printer after reinstalling the cartridge

Users report voltage readings below 1.1V on failing batteries, while working ones should measure closer to 1.5V.

==Consumer Impact Summary==

This design flaw forces consumers to purchase expensive replacement cartridges when their existing ones still work. The issue is not disclosed by the manufacturer, and the error message misleadingly suggests replacing the entire cartridge rather than indicating the actual battery problem. The 1.5V battery is not in a compartment designed for user replacement, requiring technical skills to access and replace.

This design represents a form of planned obsolescence that artificially shortens the usable life of toner cartridges, creating unnecessary electronic waste & forcing unnecessary additional expenses on consumers of Brother printers.

==Related Incidents==

This issue affects multiple Brother printer models with a similar design:

*Brother MFC-L3770CDW experiences identical battery-related toner recognition failures<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref>
*Users of Brother printers with TN-760 cartridges have reported similar issues<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/iwpb0tp/</ref>
*The issue affects both OEM and aftermarket cartridges, though aftermarket ones may be more susceptible

One user on Reddit summarized the frustration: <blockquote>''"I am very close to trashing my Brother printer and getting something else. Are there any laser printers that DO NOT HAVE BATTERIES in their toner cartridges and have after market cartridge sources?"''<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/1272dys/</ref></blockquote>

The [[Brother Industries, Ltd.|'''Brother''']] DCP-L3550CDW printer experiences cartridge failures related to the 1.5V batteries that power the toner chip. If the printer is turned off for a prolonged period, these batteries can deplete, which results in the printer not recognizing the cartridge despite still being able to read its toner capacity.

==Issue Description==

When the battery depletes, the printer displays an error message that misleadingly tells users to replace the cartridge rather than identifying the actual battery issue. This occurs even when the toner level screen shows plenty of remaining toner, creating an artificial need to purchase new cartridges. The battery is not easy to access and is not designed to be replaced by users.[[File:Toner life screen.jpg|thumb|left|Toner life despite error screen]]

==User-Discovered Solutions==

Users have found several workarounds for this issue:

*Taking out the cartridges before turning off the printer for an extended period
*Replacing the chip of the affected cartridge with the chip from an older cartridge that still has battery power ''(the chip is attached with screws)''
*Replacing the 1.5V battery yourself if you have the necessary tools (requires soldering skills)
*Keeping the printer perpetually turned on to avoid battery depletion

According to users on Reddit<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/</ref>, removing all toner cartridges before restarting the printer & then reinserting them sometimes fixes the issue temporarily. As one user who provides managed print services noted: <blockquote>''I have confirmed 100% the printers themselves often short out the chips on toners. Aftermarket or OEM, when printer is rebooted or loses power. Remove all toners when restarting, then put them back in.''<ref>[https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/]</ref></blockquote>

==Battery Replacement Process==

As documented on the Ambor blog<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref> for the similar Brother MFC-L3770CDW model:

1. Take out the toner cartridge

2. Locate the chip contacts and slide the chip out by gently pressing to one side

3. Identify the small watch battery (marked as LR521/AG0, a 1.5V battery)

4. Using a paperclip, carefully push out the old battery

5. Replace with a new battery, keeping track of which side is positive (+ side down in most cases)

6. Reinsert the chip into the cartridge

7. Power cycle the printer after reinstalling the cartridge

Users report voltage readings below 1.1V on failing batteries, while working ones should measure closer to 1.5V.

==Consumer Impact Summary==

This design flaw forces consumers to purchase expensive replacement cartridges when their existing ones still work. The issue is not disclosed by the manufacturer, and the error message misleadingly suggests replacing the entire cartridge rather than indicating the actual battery problem. The 1.5V battery is not in a compartment designed for user replacement, requiring technical skills to access and replace.

This design represents a form of planned obsolescence that artificially shortens the usable life of toner cartridges, creating unnecessary electronic waste & forcing unnecessary additional expenses on consumers of Brother printers.

==Related Incidents==

This issue affects multiple Brother printer models with a similar design:

*Brother MFC-L3770CDW experiences identical battery-related toner recognition failures<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref>

*The issue affects both OEM and aftermarket cartridges, though aftermarket ones may be more susceptible

One user on Reddit summarized the frustration: <blockquote>''"I am very close to trashing my Brother printer and getting something else. Are there any laser printers that DO NOT HAVE BATTERIES in their toner cartridges and have after market cartridge sources?"''<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/1272dys/</ref></blockquote>

The [[Brother Industries, Ltd.|'''Brother''']] DCP-L3550CDW printer experiences cartridge failures related to the 1.5V batteries that power the toner chip. If the printer is turned off for a prolonged period, these batteries can deplete, which results in the printer not recognizing the cartridge despite still being able to read its toner capacity.

==Issue Description==

When the battery depletes, the printer displays an error message that misleadingly tells users to replace the cartridge rather than identifying the actual battery issue. This occurs even when the toner level screen shows plenty of remaining toner, creating an artificial need to purchase new cartridges. The battery is not easy to access and is not designed to be replaced by users.[[File:Toner life screen.jpg|thumb|left|Toner life despite error screen]]

==User-Discovered Solutions==

Users have found several workarounds for this issue:

*Taking out the cartridges before turning off the printer for an extended period
*Replacing the chip of the affected cartridge with the chip from an older cartridge that still has battery power ''(the chip is attached with screws)''
*Replacing the 1.5V battery yourself if you have the necessary tools (requires soldering skills)
*Keeping the printer perpetually turned on to avoid battery depletion

According to users on Reddit<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/</ref>, removing all toner cartridges before restarting the printer & then reinserting them sometimes fixes the issue temporarily. As one user who provides managed print services noted: <blockquote>''I have confirmed 100% the printers themselves often short out the chips on toners. Aftermarket or OEM, when printer is rebooted or loses power. Remove all toners when restarting, then put them back in.''<ref>[https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/]</ref></blockquote>

==Battery Replacement Process==

As documented on the Ambor blog<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref> for the similar Brother MFC-L3770CDW model:

1. Take out the toner cartridge

2. Locate the chip contacts and slide the chip out by gently pressing to one side

3. Identify the small watch battery (marked as LR521/AG0, a 1.5V battery)

4. Using a paperclip, carefully push out the old battery

5. Replace with a new battery, keeping track of which side is positive (+ side down in most cases)

6. Reinsert the chip into the cartridge

7. Power cycle the printer after reinstalling the cartridge

Users report voltage readings below 1.1V on failing batteries, while working ones should measure closer to 1.5V.

==Consumer Impact Summary==

This design flaw forces consumers to purchase expensive replacement cartridges when their existing ones still work. The issue is not disclosed by the manufacturer, and the error message misleadingly suggests replacing the entire cartridge rather than indicating the actual battery problem. The 1.5V battery is not in a compartment designed for user replacement, requiring technical skills to access and replace.

This design represents a form of planned obsolescence that artificially shortens the usable life of toner cartridges, creating unnecessary electronic waste & forcing unnecessary additional expenses on consumers of Brother printers.

==Related Incidents==

This issue affects multiple Brother printer models with a similar design:

*Brother MFC-L3770CDW experiences identical battery-related toner recognition failures<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref>
*Users of Brother printers with TN-760 cartridges have reported similar issues<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/iwpb0tp/</ref>
*The issue affects both OEM and aftermarket cartridges, though aftermarket ones may be more susceptible

One user on Reddit summarized the frustration: <blockquote>''"I am very close to trashing my Brother printer and getting something else. Are there any laser printers that DO NOT HAVE BATTERIES in their toner cartridges and have after market cartridge sources?"''<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/1272dys/</ref></blockquote>

==User-Discovered Solutions==

Users have found several workarounds for this issue:

*Taking out the cartridges before turning off the printer for an extended period
*Replacing the chip of the affected cartridge with the chip from an older cartridge that still has battery power ''(the chip is attached with screws)''
*Replacing the 1.5V battery yourself if you have the necessary tools (requires soldering skills)
*Keeping the printer perpetually turned on to avoid battery depletion

According to users on Reddit<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/</ref>, removing all toner cartridges before restarting the printer & then reinserting them sometimes fixes the issue temporarily. As one user who provides managed print services noted: <blockquote>''I have confirmed 100% the printers themselves often short out the chips on toners. Aftermarket or OEM, when printer is rebooted or loses power. Remove all toners when restarting, then put them back in.''<ref>[https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button https://www.reddit.com/r/printers/comments/v8imcc/comment/ibre9kx/]</ref></blockquote>

==Battery Replacement Process==

As documented on the Ambor blog<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref> for the similar Brother MFC-L3770CDW model:

1. Take out the toner cartridge

2. Locate the chip contacts and slide the chip out by gently pressing to one side

3. Identify the small watch battery (marked as LR521/AG0, a 1.5V battery)

4. Using a paperclip, carefully push out the old battery

5. Replace with a new battery, keeping track of which side is positive (+ side down in most cases)

6. Reinsert the chip into the cartridge

7. Power cycle the printer after reinstalling the cartridge

Users report voltage readings below 1.1V on failing batteries, while working ones should measure closer to 1.5V.

==Consumer Impact Summary==

This design flaw forces consumers to purchase expensive replacement cartridges when their existing ones still work. The issue is not disclosed by the manufacturer, and the error message misleadingly suggests replacing the entire cartridge rather than indicating the actual battery problem. The 1.5V battery is not in a compartment designed for user replacement, requiring technical skills to access and replace.

This design represents a form of planned obsolescence that artificially shortens the usable life of toner cartridges, creating unnecessary electronic waste & forcing unnecessary additional expenses on consumers of Brother printers.

==Related Incidents==

This issue affects multiple Brother printer models with a similar design:

*Brother MFC-L3770CDW experiences identical battery-related toner recognition failures<ref>https://blog.ambor.com/2025/02/brother-mfc-l3770cdw-toner-fix.html</ref>
*Users of Brother printers with TN-760 cartridges have reported similar issues<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/iwpb0tp/</ref>
*The issue affects both OEM and aftermarket cartridges, though aftermarket ones may be more susceptible

One user on Reddit summarized the frustration: <blockquote>''"I am very close to trashing my Brother printer and getting something else. Are there any laser printers that DO NOT HAVE BATTERIES in their toner cartridges and have after market cartridge sources?"''<ref>https://www.reddit.com/r/printers/comments/v8imcc/aftermarket_brother_toner_no_toner_bad_chip/comments/1272dys/</ref></blockquote>

The Brother DCP-L3550CDW printer experiences cartridge failures related to the 1.5V batteries that power the toner chip. If the printer is turned off for a prolonged period, these batteries can deplete, which results in the printer not recognizing the cartridge despite still being able to read its toner capacity.

==Issue Description==

When the battery depletes, the printer displays an error message that misleadingly tells users to replace the cartridge rather than identifying the actual battery issue. This occurs even when the toner level screen shows plenty of remaining toner, creating an artificial need to purchase new cartridges. The battery is not easy to access and is not designed to be replaced by users.[[File:Toner life screen.jpg|thumb|left|Toner life despite error screen]]
