Third-party status
UnknownOwners report blocks after updates; no firmware version confirmed
Epson says non-Epson 232 cartridges that worked before a firmware update may stop working, and XP-4200 owners have reported exactly that from 2024 through September 2026. No source confirms which firmware version did it, so we mark the status Unknown; if compatible ink works today, don't accept the update.
What to do now
- Decline the update prompt and turn off automatic update checks in Epson Software Updater (set the check interval to Never), as described in a third-party guide for this model.[9][1]This only protects cartridges that work now. Skipping updates also skips security fixes. We have not checked the on-printer menu ourselves.
- Some owners report reflashing older firmware by starting the printer in recovery mode (power off, then hold Power, Down, Left and Cancel) and running a firmware updater over USB.[4][7]Disputed: others say it failed, one says the printer got stuck in update mode, and the older files shared on Reddit are from unofficial hosts, not Epson. It can brick the printer and is unsupported by Epson.
What to buy instead
- Genuine Epson 232 / 232XL. Always recognized. Epson lists T232 black, cyan, magenta and yellow plus 232XL high-capacity.
- Compatible 232 with a firmware return policy. Only if your printer has not taken the update. Ask what happens if an update rejects them.

Also applies to: XP-4205 (Epson's support pages cover the XP-4200 and XP-4205 together). Other 232 printers include the WorkForce WF-2950.
Third-party and remanufactured cartridges
- Epson's XP-4200/XP-4205 support page says the printer is designed only for genuine Epson cartridges, that firmware updates may affect third-party ink, and that non-Epson or altered cartridges that worked before an update may not continue to work.[1][2]
- Owners on r/printers and r/Epson report that after accepting a firmware update, the XP-4200 stopped recognizing compatible cartridges and would not print or scan until genuine ink was installed. Reports are dated March 2024, February 2025, July 2025, March-April 2026, June 2026 and September 2026.[4][5][6][7]
- Cleaning the cartridge chips and reseating them did not help, according to one owner in 2026.[6]

Firmware that blocked cartridges
- Epson does not publish which XP-4200 firmware version changed cartridge checks, so we list no blocking version. Owners name firmware files FWCK65TL_IT12O6 (dated 10-06-2024) and IT12Q6 as the one an owner's printer had in September 2026; these are owner reports, not Epson statements.[4]
- In September 2026 one owner said Epson's updater refused to install the older IT12O6 file ('Downgraded (It can not be updated)') after the latest update, so the update could not be undone that way.[4]
- Epson's European download center listed an XP-4200 Series Firmware Updater version IT16QA dated October 7, 2026 when we checked. We found no report yet on whether it affects third-party cartridges.[8]
To see your version, print a printer status report or open the printer's web page. Compare it with the firmware list.
Workarounds that sources back up
- Decline the update prompt and turn off automatic update checks in Epson Software Updater (set the check interval to Never), as described in a third-party guide for this model.[9][1] This only protects cartridges that work now. Skipping updates also skips security fixes. We have not checked the on-printer menu ourselves.
- Some owners report reflashing older firmware by starting the printer in recovery mode (power off, then hold Power, Down, Left and Cancel) and running a firmware updater over USB.[4][7] Disputed: others say it failed, one says the printer got stuck in update mode, and the older files shared on Reddit are from unofficial hosts, not Epson. It can brick the printer and is unsupported by Epson.
What does not reliably work
- Removing, cleaning and reseating third-party cartridges after an update did not restore recognition for one owner.[6]
- Paid 'chipless firmware' from a third-party site: owners in 2025-2026 report it failed to install on the XP-4200 ('Data file is not found') or did not work.[4][7]
- Rolling back with Epson's own updater normally refuses a downgrade outside recovery mode, per owners.[4]

What we could not verify
- Which XP-4200 firmware version first blocked third-party 232 cartridges (Epson does not say; owner-named versions are unconfirmed).
- Whether Epson's October 7, 2026 firmware IT16QA changes cartridge checks.
- Whether firmware recovery-mode rollback still works on current units; reports conflict.
- We could not open the Reddit threads directly; quotes come from indexed copies.
