experiencing a print quality issue and want to see if the cleanings are
improving the print quality, print a Print Quality Check Sheet (PQCS) after the
first cleaning and then print another PQCS after repeating the print head
cleaning steps at least three (3) more times (4 total cleanings).
You can then compare the two Print Quality Check Sheets.

This issue will only occur if an ink cartridge(s) is or was installed inthe wrong position (slot) in the machine. When a cartridge is installed, the ink tube system is filled with the ink from the cartridges, to prepare the machine for printing. If the cartridge is inthe wrong position the tube will fill with the wrong color.

To resolve this issue you will need to clean the print head.
