Ink Supplies Troubleshooting
Reseat You are recommended to start the printhead removal process from the front
panel, but instead of removing the printhead, simply press the OK key on the
front panel.
Replace You are recommended to remove the printhead and then reinsert it; if that
fails, clean the electrical connections; if that fails, replace the printhead with
a new printhead.
Replacement
incomplete
A printhead replacement process has not completed successfully, relaunch
the replacement process and let it finish completely (it is not needed to
change the printheads).
Remove The printhead is not a suitable type for use in printing (for instance, a setup
printhead).
