Print head maintenance.

First thing is to get the carriage to move into the ink cartridge replacement position Usually pressing the paper feed button will make the carriage move. Once the carriage moves from it's "parked" position just unplug the printer. In addition the flushing the print heads of old ink and unclogging it the face of the print head can attract dust, paper lint and pet hair. You can clean the face of the print head using a folded paper towel or coffee filter. Sometimes you will need to cut the paper towel or coffee filters into strips ¾ of an inch to 1 inch wide. Then dampen the paper towel or coffee filter with warm distilled water (you will want the paper towel/coffee filter to be damp but not dripping) Now you place the damp paper towel/coffee filter in the path of the  print head. Then pass the carriage over the paper towels/coffee filters to remove the foreign matter from the face of the print head.  (see photo) As you slide the print head over the paper towel/coffee filters a few times you will start the see the debris is being removed from the face of the print head. It is not uncommon to perform this process several times to completely remove all of the foreign matter from the print head's face.
