HP 1220c double image

there might be a problem with the encoder: remove it, observe it closely with a magniying glass, and you have to see a vertical lines pattern all along the enconder, without no blurs or missing or erased parts on it. Try to clean it with alcohol and a cloth but be careful no to erase the patterns i described early. If there are missing lines in the pattern you'll need to replace.

What is the encoder? a strip of semitransparent plastic that goes in the back of the cartridge carriage.

There are known issues if you are not using geniue hp cartridges.
Can you try the printer in another computer to see if its a issue with your computer or a internal printer issue?

check you cartridge, is it new and genuine, if you have not troubles in cartridge, check the cleannig station

THIS IS A CARTRIDGE OR PAPER JAM ERROR.CHECK FOR ANY PAPER STUCK IN THE PRINTER,ALSO TRY REPLACING INK CARTRIDGES

Print cartridge
When the print cartridge contacts are dirty and the printer cannot detect/communicate with print cartridge.
Clean the contact points on the cartridges with a dry, lint-free cloth.
1. Open the top cover of the printer.
2. Remove the print cartridges.
3. Clean the copper-colored contact points on the cartridges with a damp, lint-free cloth. Use a dry, lint-free cloth to remove moisture from the contacts.
5. Insert the cartridges back into the printer.
6. Close the top cover.
7. Try printing again.
If you still cant communicate try with new cartridge .

the cartrdges contacts are well, the ink it is clogged in the printheads, take out the cartridges, put them in a wet towelwith windows cleaner liquid, just the head height, let rest 12 hours, clean and dry the heads and try to print, sometimes need a second time on liquid. good luck

Did you try both cartridges? Sometimes a fried circuit on the color cartridge will cause a out of ink on the black even when the black is new. Double check that you are using the correct cartridge for the printer. and look at the copper/gold contacts in the printer where the cartridge goes. look for dried ink or tears. Clean with a Q-tip dipped in water. CAREFULLY. If it's torn.... enjoy your trip to walmart.

If you take out the Cartridge, you will see a peace that can move on the botom of the Cartridge, take a tissue and fold it double, use it to clean the green roller that is underneath this cover. Do not press to hard, as you will damage the Printhead(green roller). If you buy a new Print Cartridge, your problem will also be solved Regards

This happens when the connections on the cartridge get old. Especially when you refill or buy non HP Cartridges, try buying brand new hp cartridges and you might be able to get a couple refill out of them before this happens again.
