Most likely this is a print head issue. The print head is what the cartridges sit in inside of the printer. To attempt to resolve it, do the following:(1) Open the printer and wait for the carriage to slide over(2) Remove the ink cartridges from the print head.(3) Use cotton swabs dipped in hot water or a mix of hot water and isopropyl alcohol to thoroughly clean the print head and the electronic contacts on each ink cartridge.(4) Repeat this until there is no ink residue coming off on the cotton swab.(5) Once finished, allow to dry and replace the cartridges(6) Try to print something nowIf that does not work then you have one of two possibilities:(1) One of the ink cartridges is defective and causing the error(2) If it's definitely not that, then the print head will need to be replaced.Thanks and please click the green ACCEPT button after reviewing my answer.Thanks,Rob
I have followed your instructions, cleaned all the cartridges and the lift-out cartridge holder in the print head , and the cartridge contact points in the print head; all to no avail, same result. No black ink, even with a new genuine cartridge and no sign ofthe PGBK check pattern that is printed with the nozzle check function. I guess that means a new print head?
You will need to replace the printhead
