Refilled cartridge not recognized / incompatible after refill — HP, Epson, Canon, Brother chip reset
Technician
Technician
• The cartridge chip still reports “used/empty”. You need a chip reset or a fresh compatible chip.
• Cartridge Protection or recent firmware update blocks third‑party chips.
• Dirty or bent gold contacts / ink on the flex PCB causes poor connection.
• Air in the sponge after refill – printer sees no pressure (“depleted”).
Plan: clean contacts, power‑cycle the printer, disable protection, then reset the ink level (chip swap or resetter) and prime the cartridge.
Technician
1) Power cycle: with the printer on, pull the power cord at the rear → wait 60s → plug directly to wall → power on. This clears cartridge memory.
2) In HP Smart or the printer’s Web Server (EWS) → Settings → Supply Settings → turn Cartridge Protection Off and allow non‑HP cartridge use.
3) Remove the black 962XL. Clean the copper contacts on the cartridge and inside the carriage with a lint‑free cloth slightly moistened with isopropyl alcohol. Dry 5 minutes.
4) Reinsert firmly until it clicks. If still not recognized, proceed to chip reset below.
Technician
• Chip swap: move a known‑working chip from a new/genuine empty to the refilled shell (use double‑sided tape). This resets ink level to “full/OK”.
• External chip resetter tool: compatible resetters reprogram the EEPROM on older lines (e.g., 950/951/932/933). For newer locked chips, use upgradeable replacement chips matched to your firmware.
• Update strategy: keep HP firmware auto‑update off (EWS → Web Services or Printer Maintenance) so updated firmware doesn’t block third‑party chips.
After chip fix, run a printhead priming (print a solid black page or run “Clean Printhead”) to remove air introduced during refill.
Technician
• Many Epson carts use auto‑reset chips (ARC). Remove the cart for 10+ seconds → reinstall; some ARCs reset when the ink chamber is refilled and voltage rises.
• If it still fails, use a compatible chip resetter for your series and hold the cart to the resetter pins until the LED indicates success.
• Ensure firmware updates are paused in Epson Software Updater to avoid third‑party chip blocks.
• Run Nozzle Check then Head Cleaning to prime after recognition.
Technician
• These chips don’t truly reset without specialized tools. Canon allows single‑cartridge/continue mode: when “Ink is out” appears, hold the Stop/Resume button (triangle) for 5–10 seconds to disable ink level detection for that cartridge. You must monitor ink to avoid running dry.
• Clean the gold contacts and the printhead nozzles, then run Cleaning → Deep Cleaning.
• For Canon PGI/CLI tanks (separate head), use ARC chips or swap chips from working originals.
Technician
• Inspect the chip window on the cart; ensure the small PCB is seated and not covered by label/ink.
• Use a compatible reset chip or a chip resetter for your series; many Brother models accept ARCs.
• In the driver, disable “Stop printing when low” so you can continue after refill (you still need readable chips for recognition).
• After recognition, run Ink Volume → Purge or a cleaning cycle to prime.
Technician
• Try another known‑good original with a valid chip to rule out a damaged carriage/board.
• Check for bent spring pins inside the carriage; they must be even and springy.
• Update/downgrade printer firmware only from the official vendor site; avoid unofficial firmware. Some models require staying on a specific version to allow third‑party chips.
• For refillable carts, ensure the air vent plug is open; a sealed vent causes “depleted” or streaks.
• As a temporary workaround, most printers allow single‑cartridge mode (black‑only) to keep printing.

Quick answer: the accepted fix
Accepted fix when refilled cartridge not recognized: Clean copper contacts, power cycle, disable cartridge protection/auto‑updates, then reset the cartridge chip (ARC/resetter or chip swap) to reset ink level. Finally prime the printhead (Nozzle Check → Cleaning) and print a test page.
“Incompatible cartridge” after a firmware update (HP/Epson/Canon/Brother)
If recognition failed right after a firmware update, revert if an official rollback exists or disable future auto‑updates. Many vendors periodically block third‑party chips. Use upgradeable chips or a chip resetter matched to your current firmware.
How to verify the chip reset worked
Print a Nozzle Check or a 4‑color test page. The printer should show ink levels present and allow printing without “missing/incompatible” messages. If streaky, run one Cleaning and let the printer rest for 10 minutes to clear air.
Refilled cartridges — safe troubleshooting checklist
Most recognition issues come from dirty contacts, blocked vents, or chips not reset after refill.
Quick path: verify chip type → clean contacts → reset/swap chip → disable protection → prime and align. Use genuine‑spec ink to avoid clogs, and never print with an empty sponge — it can burn out thermal heads.

FAQ
Why is my refilled cartridge not recognized?
Chips retain “empty” status, contacts are dirty, or firmware blocks third‑party chips. Clean contacts, power cycle, reset or swap the chip, and disable auto‑updates.
How do I reset a cartridge chip?
Use a compatible chip resetter (Epson/Brother and some HP), or move a working chip from an original cart to your refilled one. For Canon PG/CL, hold Stop/Resume 5–10s to disable monitoring.
Printer says “incompatible” after firmware update — what now?
Turn off auto‑updates. If the vendor provides one, apply an official firmware rollback. Then use updated chips that match your firmware.
Can I print with only black while I sort color chips?
Yes, many models support single‑cartridge mode or “grayscale/black only” in driver settings. Output quality may be reduced.
Will refilling damage my printer?
Use quality ink and avoid running dry. Prime and align after refilling. Problems arise mainly from air ingestion or blocked nozzles, not from the refill itself.
| Symptom | Likely cause | Quick fix |
|---|---|---|
| “Cartridge missing/incompatible” | Chip not reset; firmware block | Reset/swap chip; disable auto‑updates; reseat firmly |
| Shows empty after refill | Chip stores low status | Chip resetter or ARC; on Canon PG/CL hold Stop 5–10s |
| Recognized but prints blank/streaky | Air in sponge; clogged nozzles | Prime/Nozzle Check → Cleaning; open air vent; align |
| Only one color not detected | Bent carriage pins; dirty contact | Inspect pins; clean copper pads with IPA; try known‑good cart |
Step‑by‑step (Windows/macOS — recognition)
- With the printer on, unplug power → wait 60s → plug in and restart (memory reset).
- Remove the cartridge → clean contacts on cart and carriage → dry thoroughly.
- Disable Cartridge Protection/auto‑updates (EWS/HP Smart; Epson Software Updater; Canon/Brother utilities).
- Perform a chip reset (resetter/ARC) or chip swap from a working original.
- Reinsert, run Nozzle Check → one Cleaning, then print a test page and align.
