I cleaned all the copper contacts and the springs that make a connection with them with isoprophyl alcohol. As you can see the black contact is the most corrupted. Below you will see the contacts that are covered in ink which is causing the communication issue. The solution to this problem is to remove the print head and service the contacts and apply aluminum enhance the contact detection.įirst thing I did was remove the print head from the printer and its cartridges then took out the two screws along with the ribbon cable on the back.Īfter that gently peel back the board and ensure you dont damage the bottom cable which is attached to the ink vents. This throws of the signals sent to and retrieved from the print head to the printer’s main board in terms of knowing any information about the cartridge such as if the cartridges are inserted properly and its ink levels. The printer error is common with this model, after a period of time waste ink builds up from constant cleaning of the print head and causes the contacts connected on the back the print head board to get corroded. When received I began getting the printer failure along with the black cartridge is missing or damaged error message. He bought a new cartridge and replaced it and the same issue is happening. The customer says the printer gave the error initially that the black cartridge is missing or damaged.
