Common Causes
Step-by-Step Fix
Preventive maintenance for high-density dye-sub thermal printheads. Tested and verified on Canon SELPHY CP 1200 Compact Photo Printer.
Clean Thermal Printhead Elements
Unplug printer and remove ink cassette. Wipe the shiny thermal heating strip with a specialized thermal cleaning pen or lint-free swab with 99% isopropyl alcohol.
Use Anti-Static Dust Shielding
Blow off any dust from the paper feed tray. Static electricity attracts hairs and dust directly to clean paper.
Wipe Backside Feed Rollers
Open rear exhaust panel and gently rotate rollers to remove any sticky dust bunnies.
