firmware, the RADF will be compatible with models 7020, 7025, 7030, and 7035.
2. The RADF CB Boot codes can be identified based upon the ROM label attached to IC3, which is
located above CN7 on the RADF CB.
ROM labels:
13GL89013 or before = Boot code 11.
13GL89014 = Boot code 20.

Light copies and internal test prints.DESCRIPTION: SOLUTION ID:
128915
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

FS107, F77-5 at power up.DESCRIPTION: SOLUTION ID:
96164
SOLUTION:
CAUSE: The FS107 conveyance casing is broken.
The paper pressure assembly, which is driven by the paper pressure motor (M707), is unable to
properly initialize at power up. The rear plastic portion of the conveyance casing, which holds in
place shaft holder/A (p/n 13GQ76020), is broken. Shaft holder/A supports the rear side of the
Pressure camshaft assembly (p/n 13GQ45410). With the rear side of the pressure camshaft
assembly unsupported, the pressure camshaft lifts up out of position when rotating, this causes a
bind resulting in the F77-5 code.
SOLUTION: Replace the conveyance casing (p/n 13GQ45010).
Notes:
1. A possible interim solution is to first glue the broken plastic portion back in place, and then
