Caution
When servicing the printer, before turning on the printer, you
should always make sure that the head tilt cam gear is latched by
the head tilt solenoid and that the head tilt cam gear is disengaged
(via its missing teeth) to the drive gear. Failure to do so can cause
the printhead to be tilted and possibly "crash" into the raised
cap/wipe/purge assembly or the head restraint pin.
