66.12.36 Error

Page 1 of 6
Issue Description: Error code 66.12.36
We have found that the vast majority of these error codes are being caused by the
improper handling of the Multifunction Finisher during the moving of the finisher and
using the output tray as a handle. Moving the finisher using the output tray as a
gripping point will cause the output tray to slightly bend out of alignment with sensors
arms (Figure 2) that the tray needs to actuate as it travels up and down during
normal operation. When the sensors are not actuated when expected, a 66.12.36
error appears.

Troubleshooting
Test the sensor functionality as follows -
1. Power the device off.
2. Locate the sensor flag/arm and depress it fully with your finger and power the
device back on
3. Continue to hold the sensor flag in until the device comes to Ready.
a. The device should cycle the output tray up and down but you will notice
that the output tray will stop below the normal top or home position (this
is because the sensor flag was actuated and the tray thinks it is at the
home position).
b. The unit should come up to Ready without the 66.12.36 error. If the
device successfully comes to Ready, this would be a good indicator that
the tray is too far away from the sensor flag to engage the flag fully.
Bending the tray back into position should resolve the 66.12.36 error.
c. At this point the device will show the message “Upper Left Tray Full”.
4. If you release the flag the tray will cycle to the top and find home position.
a. If the device now shows a 66.12.36 error you will be assured that the
output tray is to far way from the front of the device and needs to be
repositioned.
5. If the unit continues to fail with the 66.12.36 error and the output tray does not
move up or down, this would indicate that the M6 motor is not functioning. To
reduce service costs we have put in place a new service part for the (M6) Stacker
Bin Lift Motor assembly. The part number is 4G1-3999-030CN. See the work
instructions document “Stacker Bin Lift Motor (M6) Replacement”.

Workaround or Solution
Note: If this corrective measure does not correct the 66.12.36 error code, DO NOT
replace the whole finisher. If the 66.12.36 error reoccurs, please replace (M6) Stacker Bin
Lift Motor assembly. The new part number is 4G1-3999-030CN
Corrective Measure:
Using two hands (placed as seen in Figure 4) gently, but firmly, push down on the tray
until the gap between the output tray and the finisher’s mainframe (Figure 5) is 1-2 mm
after the tray is released.
Note: The tray must not rub against the cover of the finisher while it travels up and down
during normal operation.
New Gap =
1-2 mm
Firmly, but gently, press
down the output tray with
two hands as shown to
reduce the gap.

Background
This error can occur at anytime during the life of the product.
 When error occurs immediately after installation, the most likely cause is from the
improper moving of the Multifunction Finisher during unpacking and moving the
finisher across carpeting or while attaching the finisher to the printer, using the
output tray as a handle. (See figure 7) It is also possible that the output tray was
bent up slightly while in the packaging during shipping.
 When error occurs several months and beyond after being installed, the most likely
cause is from the end-user moving the finisher when removing a paper jam, moving
the finisher using the output tray as a handle. In this case, the customer needs to be
instructed on the proper method of moving the finisher by using the finisher’s main
frame and NOT the output tray. (See figures 8 and 9)
IF unit was preflighted (set-up offsite), extra care must be taken so not to bend the output
tray when moving the unit including avoiding shrink wrapping too tightly, improperly
strapping of the device into transport vehicle, moving device down sidewalks, hallways,
elevators, across carpeting, etc., when delivering device to customer site. The output tray
must never be used as a grasping point when moving the multifunction finisher.
