3.3.2 Installing and removing the purge unit
When removing the purge unit, rotate the gear inside the purge unit clockwise and lower the
carriage lock pin. Align the phase of the black pump gear so that the cap part and
pre-ejection opening will rise.
Unhook the lock spring of the ink tank replacing cover and return the lock to the front
position. Disconnect the connector from the control board, and pull out the purge unit by
pressing down the printer chassis claw placing at the front. When removing the purge unit,
be careful for the ink stain as ink is attached around the tubes coming out from the bottom or
at the bottom surface.
3.3.3 Removing and installing tap screws
This printer uses tap screws to fasten the external cover and printer unit. As the removed
tap screws have residue from the mold in which the internal thread was made, the residue
may crush the screw threads when screws are reused without cleaning. Therefore, clean off
the residue from tap screws before reusing them, or use a new tap screw.
