DF314, parts update to Driving release roller/B (p/n 13GL45161).DESCRIPTION: SOLUTION ID:
118069
SOLUTION:
Driving release roller/B (p/n 13GL45161) has been changed to prevent J62-5 jamming with 8.5x14
or 11x17 thick stock originals in a 2:2 or 2:1 mode at 50% reduction. The diameter of the roller part
of Driving release roller/B has been reduced from 14mm to 13mm. The color of the roller part on
the new style the Driving release roller/B is black (old style is white). The new style Driving release
roller/B has been installed in production DF314's s/n 13GL67168 and above.

USAGE:
1
DF314, J62-5 in 2:2 or 2:1 mode, 50% reduction and with 8.5x14 or 11x17 thick stock
originals.
DESCRIPTION: SOLUTION ID:
118079
SOLUTION:
CAUSE: The feeding of 8.5x14 or 11x17 thick stock originals in a 2:2 or 2:1 mode at 50% reduction
is applying excessive load to the Original reverse motor (M303) and the Original conveyance motor
(M302). The lead edge and trail edges of longer originals (8.5x14/11x17) pass between the
reverse roller and the paper exit roller at the same time. The addition of thick stock originals and
the operation of 50% reduction will cause excessive drive binds to M303 and M302.
SOLUTION: The diameter of the roller part of the paper exit roller (Driving release roller/B) has
been reduced from 14mm to 13mm. The new part number of the Driving release roller/B is (p/n
13GL45161).
Notes:
1. The color of the roller part on the new style the Driving release roller/B is black (old style is
white).
2. The new style Driving release roller/B has been installed in production DF314's s/n 13GL67168
and above.
3. Refer to the DF314 parts catalog (3/2001) page 10 item 11 for part location.
USAGE:
1
Erratic operation when using the repeat mode, or photo mode.DESCRIPTION: SOLUTION ID:
118209
SOLUTION:
CAUSE: There is interference from a light source above the copier, resulting in inaccurate
detection of the original outer boundary.
SOLUTION: Program external incorrect detection prevention in the 25 mode:
1. Power the copier OFF.
2. Access the 25 mode (power the copier ON, while pressing the 2 and 5 keys).
3. Touch [1. Software SW] on the touchscreen.
4. Select software dipswitch 13-6 using the arrow keys.
5. Set the switch to OFF (0).
6. Select software dipswitch 13-7 using the arrow keys.
7. Set the switch to ON (1).
8. Power the copier OFF/ON to exit the 25 mode.
Note: This setting will reduce the effect of extraneous light when determining the outer boundary of
the original. However, the intensity of the external light source may be at a level beyond the
machine compensation capability. If, the problem is still experienced after implementing this
solution, the copier should be relocated away from the light source.
