Canon error code 1372
Quick answer
Print head replacement can't proceed because the maintenance cartridge is almost full. Stop the print head replacement, close the scanning unit/cover, and replace the maintenance cartridge first before attempting the print head replacement again.
Before you try the solution
- 1. Copy the complete message exactly as shown, including any letters, spaces, or punctuation around 1372.
- 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
- 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.
