Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Confirm the exact PIXMA model before ordering ink.
- 2
Compare the cartridge number with Canon's model support page, not only a retailer title.
- 3
For banding or color loss, print DeviceOK's color reference before deciding whether the cartridge or printhead path is responsible.
Limits
What this answer does not prove
- Ink numbering can vary by sales region.
- A cartridge-compatible result does not prove a third-party/refilled cartridge will perform correctly or be supported by Canon.
