Troubleshooting Tips
"Ink cartridge cannot be recognized" alert: Reseat each tank and wipe the gold chip contacts with a lint-free cloth.
Streaky prints: From the MX922 touchscreen, run Setup > Maintenance > Cleaning. If issues persist, run Deep Cleaning.
Alignment off: After installing a new tank, run Setup > Maintenance > Print Head Alignment.
Firmware-blocked cartridges: Canon firmware updates can sometimes reject third-party chips. If you use compatibles, decline firmware updates when prompted.

Frequently Asked Questions
What’s the difference between PGI-250 and CLI-251 Black?
The PGI-250 is a pigment black used for crisp text on plain paper. The CLI-251 Black is a dye-based photo black used for the dark tones in photos.
Can I mix PGI-250 standard and PGI-250XL?
Yes — the tanks are interchangeable. Many users run all XL tanks for the best cost-per-page.
Does the MX922 need setup cartridges?
No, your replacement tanks install directly. Setup ink is only used the first time you unbox a brand-new printer.
How long do PGI-250XL / CLI-251XL tanks last?
The XL pigment black yields about 500 pages, each XL color about 665 pages, and the XL photo black about 1,295 4x6 photos — depending on coverage.
Why does Canon show a "Non-genuine cartridge" message?
This is a standard Canon warning when using compatibles. Press and hold Stop for 5 seconds and printing will continue normally.
