Great instructions. Got printer working again after the black print head completely dried up.
OMG the print head cleaning area was so full of old ink. It really needed removing and soaking but could not see how to remove it under the sea of old ink so had to mop the worst off with paper towel and reassemble. Works OK now.
Great instructions to this stage. Underside of print head can be washed under warm running water if you keep the end with the electronics dry.
