Canon PIXMA Support Code 5100
Canon's model manuals describe 5100 as a printer error and direct users to power the printer off and check whether print-head/cartridge-holder movement is being impeded by packing material, jammed paper, or other obstructions. Exact instructions vary by model.
Start hereUse the 5100 procedure for your exact PIXMA series. Do not force the carriage or copy instructions from a different Canon model blindly.
What to check
Step 1
Cancel printing and turn the printer off.
This is the starting action in Canon's 5100 instructions for multiple PIXMA families.
Step 2
Check for obvious obstructions in the carriage/holder path.
Canon's exact wording differs by series, but examples include jammed paper and material preventing the holder from moving.
Step 3
Check model-specific items in the official manual.
Some Canon models include additional checks, such as print-head lock-lever position.
Step 4
Power the printer back on and retest.
If 5100 persists after the safe checks, use Canon's model support page or service route.
