Important: The instructions below apply to standard Canon series printers. Always disconnect power cables before reaching inside internal paper paths or hardware assemblies.
Recommended Resolution Steps
- 1
Turn off the printer, unplug the power cable, and open the main scanning unit cover.
- 2
Check the entire width of the carriage track for crumpled paper, staples, or packing foam.
- 3
Find the thin, clear plastic timing strip (encoder film) stretched horizontally behind the ink carriage.
- 4
Carefully wipe both sides of the clear strip with a dry, lint-free cloth—avoid pulling or bending the strip.
- 5
Close the cover, plug the printer back in, and run a nozzle check to confirm the carriage moves smoothly.
