The ADU door may not completely close without releasing the open/close knob.DESCRIPTION: SOLUTION ID:
125042
SOLUTION:
CAUSE: To improve operability when the ADU door is closed, the open/close knob and shape of
the shaft has been changed in manufacturing.
SOLUTION: This change will allow the ADU door to close completely without having to release the
open/close knob. The old style open/close knob (p/n 26NA50091) is fixed to the shaft with a screw,
the new style open/close knob (p/n 26NA51110) is fixed the shaft with an E-ring. The old style and
new style open/close knobs are not interchangeable due to the change in shape of the shaft.

The trail edge of the copy is faded and light on the second side.DESCRIPTION: SOLUTION ID:
131020
SOLUTION:
CAUSE: Internal arcing within the high voltage casing attached to the right side ADU cover,
resulting in loss of transfer current to the T/S corona unit.
SOLUTION: To check the high voltage casing for signs of arcing, perform the following:
1. Power the copier OFF.
2. Open the ADU cover (p/n 26NA50010).
3. Remover the two (2) screws (p/n 00Z193061), which attach the high voltage casing/A to the
ADU cover.
4. Remove one (1) screw (p/n 00Z193061) from the upper shaft holder (p/n 26NA50630), which
will allow the claw shaft to be moved and permit removal of the high voltage casing from the ADU
cover.
5. Separate casing/B (p/n 26NA50532) from casing/A. Inspect the entire assembly for any signs of
arcing. Replace the insulating sheet (p/n 26NA50971), high voltage fixed parts (p/n 26NA50950),
high voltage part upper (p/n 26NA50460), or high voltage part assembly (p/n 26NA-5260) as
