Canon PIXMA TS6420a 12 ppm Wireless Compact All-in-One Inkjet Printer with Auto Power On/Off MECH-HEAD-CLOG Error Fix: Print Head Nozzle Clog — Missing Colors or Streaks

One or more print head nozzles are clogged, causing missing colors, white streaks, or banded output. This is the single most common Canon PIXMA problem and is caused by ink drying in the microscopic nozzles when the printer sits unused for more than 1-2 weeks. From the printer's Setup/Maintenance menu, run a Nozzle Check Pattern first to see which colors are affected. Then run a Print Head Cleaning cycle. After cleaning, print another nozzle check — it may take 2-3 cleaning cycles to clear stubborn clogs. If standard cleaning doesn't work, run a Deep Cleaning (uses more ink but applies stronger suction). On MegaTank models, flush the ink system from the maintenance menu. For severe clogs on models with removable print heads, remove the head and soak the nozzle plate in warm distilled water for 1-2 hours. To prevent future clogs, print at least one page per week.
