Canon mp390 printhead will not move with cover open

SOURCE: Canon Mp390 print problem

Hi James,

If you have replaced the printhead and cartridges and the problem still occurs then it may be the printhead contacts that are dirty. Get a cotton bud and pure alochol and lightly rub the contacts. But I would expect some sort of print out albeit not a decent one. If the above solution does not work then you may have to speak to canon as it may be a serious problem.

SOURCE: WRONG CARTRIDGE and Printhead does not move MP780

your printer ink cartridge can not access (move to middle) when you open up the cover, you may try
1) try to open right side cover you move the cartridge by hand (power off) to middle position, then take out the cartridge and reinstall it then power on, the cartridge moving right, you may open up the cover again if the cartridge go back the middle position which means your printer works normal. still stop moving go next
2) check the cartridge initcial sensor at righe side, the cartridge moving to the end of right should be touch this sensor, find out it and check there is good touch (click) by the cartridge body. adjust the sensor position maybe needed.
3) cartridge is stucked sometime also check the cartridge moving rail hard moving, need to drop oil to lubricate.
