Maybe the print head is completely clogged. Maybe there is an electrical malfunction in the print head and it is irreversible. It is unlikely that two printers would have the same issue NOT related to the print head, however, there is the very rare chance that an electrical failure in the print head can cause an electrical failure in the logic assay board -- and vice versa.
The most important thing at this point is to NOT print anything other than a nozzle check until function is restored or else risk burning out the nozzles permanently (if not already).
Obviously, all the ink cartridges must be known to function, ie have ink and the ink flows out appropriately. Some use the gentle squeeze technique to see if ink will drip out. Others uses a paper towel and press the cartridges' ink exit ports onto it to contact the sponge within and see if and how ink deposits on the paper towel.
It might be that you will need new cartridges, or flush/reset/refill the old cartridges to ensure properly functioning cartridges. The idea here is to not confuse ink starvation from poorly functioning cartridge with a problem in the print head. Remove as many confounding causes as possible to help narrow the culprit cause.
As for the print head, I would rinse under warm, not hot, water in the sink until all or little traces of ink is seen. Then soak the print head in water in a non-reactive bowl (glass, plastic, etc) containing water and several drops of liquid dish washing soap such as Dawn or Fairy with enough solution to cover the ink inlet ports of the print head. Place a folded up paper towel underneath the print head nozzle exits on the bottom - your can pump the print head up and down onto the paper towel to help hently force the solution into the print head. I change the water when it discolors or after 12 hours and change the paper towel at this time, too.
PATIENCE is the key factor here. You soak as long as your patience allows and then do it some more. I'd allow at least 24 hours if not 72 hours. Then thoroughly;y rinse the print head under the tap in the sink, gentle wipe water with a paper towel and let dry over night. Make sure no fluid is on the electrical contact area of the print head and then install back in the printer along with your new or reconditioned cartridges.
Now print a nozzle check. If nothing or only some ink appears, then try a deep clean ONE TIME ONLY and then another nozzle check. Post the nozzle checks and your observations. Let the printer sit over night - sometimes this allows for ink to seep out from the cartridges and begin flowing into the print head. The following day, try another nozzle check, post here and do nothing else with the printer till someone here give advice on next step.
Of course if the nozzle check is perfect, fingers crossed, then you are done and can start print happily again. If no change, then new printer time.
Hello Stratman,
thank you for your reply. I tried out a complete printhead cleaning as I'm use to do it as you described in the previous post.
Unfortunatly nothing happened at all but in a strange way my printhead was working pretty well before in my old printer wich got a problem with purge unit and I was thinking that it could come from the motherboard from the printer I got last week, wich could be defect because of a defect printhead ("please insert the right printhead" error msg).
What do you think about?
Best regards
