Phaser 840/850/860/8200 Color Printer - Service Manual
Definition
The printhead is unable to move on its tilt axis. The head is
unable to move on its tilt axis, because it is colliding with
something (head restraint pin, cap, poorly installed ink loader,
screwdriver.) Prior to declaring this fault, the engine has
attempted to move the process motor through enough revolutions
to disengage the head tilt mechanism, but the motor stalled. The
X-axis was then displaced to the right 3.8 mm (0.15 in.) and the
disengage was repeated, but the motor stalled again. This fault
is then declared.
