It seems simple enough, but this is one of the most effective ways of fixing printer cartridge error. Mostly, printer cartridge error occurs when the printer head is unable to identify the cartridge properly. And the basic reason behind this is that the cartridge is improperly attached.

To reattach the cartridge check the following steps :

turn on the lid of the printer and then remove the cartridge from the printer head.

Check the cartridge to make sure that there are no scratches or other damaged parts that can contribute to a printer cartridge error report.

Take note that the cartridge should not be left open for more than 30 minutes; otherwise the ink will start to dry up and the cartridge will get clogged.

take out the ink and on a soft cloth wipe the printhead down 3 times then do a cleaning on the machine
