Locking The Printhead - Xerox ii LINXSolid Inkjet 100 Service Manual

Locking the Printhead

CAUTION
CAUTION
During normal power-down, the printer tilts the printhead back and
energizes the X-axis drive to move the printhead to the far right.
This allows the printhead's tilt arm, which moves as the printhead
moves, to engage a pin protruding from the left-side printer frame.
This effectively automatically locks the printhead in place for moving
and shipping. The printer will not lock the printhead if any printer
door is open.
After servicing the printer with power off, never leave the printhead
in the tilted-forward, far-right position. Upon power-up, the
printhead will be tilted backward and the head tilt arm will crash
into the head lock pin. This can damage process gears and belts
driving the tilt arm.
After servicing the printer. When you service the printhead, X-
axis drive, cap/wipe/purge assembly or other relevant printer
components, leave the printhead in its print position, centered in
front of the drum. Upon power-up the printer can safely move the
printhead.
Manually locking the printhead. If you must manually lock the
printhead:
1. Disconnect the head tilt spring.
2. With the printer powered off, carefully tilt the printhead back
about two-thirds of the way by rotating the compound gear.
Do not allow the spring-loaded printhead to fall forward or it may
damage the drum.
3. Manually rotate the X-axis drive gear to move the printhead to
the right extreme of its travel. Ensure the lock pin on the left
side of the printer frame properly engages the slot in the head
tilt arm.
4. Rotate the X-axis gear in the opposite direction about one
rotation. This prevents the X-axis drive from binding so tightly
that the motor cannot free it upon power-up.
5. Reinstall the head tilt spring.
