3. Torque the mounting screws to 20 in./lbs.
4. Perform a “Cold” Printhead-To-Drum Spacing Adjustment,
followed by a “Hot” Printhead-To-Drum Spacing Adjustment.
X-axis Motor And Drive Assembly
Reveiw these general operation requirements before servicing the X-
axis motor and drive assembly.
•
Home Position. The printer is completely “dumb” about where
the head is other than based on motor count tracking in RAM
after homing. Accurate homing is dependent on a free moving
head/shaft assembly. When the X-axis is free to move, homing
can be verified by audibly listening to the “tick” sound as the
motor continues to drive after the head travel limit is attained.
Moving the X-axis by manually turning the gear will require
power cycling the printer to reestablish the correct home
location.
•
Friction. Print quality could suffer if the X-axis drive system
friction becomes too high. Lack of lubricant at the interface
between the nose cone and yoke can increase friction and wear
considerably. Excess friction at the leadscrew/gear interface
would also occur if not properly lubricated.
•
Parking Bind. Under unusual circumstances the X-axis could
become bound up when parked. This would most likely occur if
the interface between the gear and stop collar was not
lubricated. Drive parameters have been optimized to prevent
binding. However, if such a bind does occur, it can result in
either no X-axis movement or a delay in coming off the collar,
which would cause a positional imaging offset.
•
Power Interruption. The X-axis shaft/head assembly can
gradually move to the right when power to the printer or motor
is interrupted prior to doing a parking move. This occurs
because the thread pitch slope is steep enough to allow the gear
to rotate if unchecked by motor resistance. Home position is
lost when this happens but the printer re-homes when the
power is cycled.
Removal
1. Remove the right cover.
2. Remove the left cover. Disconnect the head-tilt spring.
3. Disconnect the X-axis motor wiring harness at the X-axis
motor.
