Detection Conditions:
- Timing & Condition -
The main control board
does not receive the
FGATE signal from the LD
control board. This can
occur after the Start key is
pressed (the image
transfer belt makes 3
revolutions) or at certain
timing points during the
copy cycle.
- FAGTE signal -
This signal is generated at
the LD control board after
the board receives the belt
mark signal from the main
control board. This signal
is used to synchronize
laser writes for the
different colors.

Possible Causes:
• Belt mark detection error
• Electrical noise
• Poor connection of
connectors
• Defective LD control
board
• Defective Main control
board

Troubleshooting Procedure:
1. Clean the belt mark (located back side of
the image transfer belt) or replace the belt
if the belt mark is dirty or has peeled off.
2. Clean the belt mark detection sensor.
3. Clean the development units’ bias
terminals.
4. Make sure the harness connectors
(CN605 & NC406) on the LD control
board and main scanner IPU board are
properly connected.
5. Make sure the harness connectors
(CN604 & CN306) on the LD control
board and main control board are properly
connected.
6. Replace the LD control board.
7. Replace the main control board.
[Signal Check]
• FGATE: CN604-A2 or TP22 on LD control
board / CN306-A9 on main control board
• Belt mark: CN220-A12, TP106, or CN212-
B11 on I/O control board / CN303-B1,
TP108, or CN306-B2 on main control
board
/CN604-B9 or TP31 on LD control board
If the machine is equipped with the
controller,
1. Make sure the connectors (CN606 &
CN101) on the LD control board and
controller I/F board are properly installed.
2. Make sure the controller I/F board is
properly connected.
3. Replace the interface board.

RTB RB023025 also mentions this problem:
Symptom:
Following ITB replacement, the rubber positioning seals around the inside edge of the belt
peel off at approximately 1-2 kD, causing SC326 or SC452.

Cause:
An insufficient amount of setting powder is applied to the ITB, causing the belt to catch the
blade and bend it backwards. The blade then pushes against a different area of the belt
(one with no roller underneath), causing the belt to bend inward and the positioning seals
to contact the Grounding Plate. The seals are then peeled off at their “joint” areas.

Troubleshooting:
Please be sure to apply a sufficient amount of setting powder to the entire surface of the
belt at replacement.

Note: When in doubt, it is better to apply slightly more powder than less.

thank you again/
I think I can do it by myself.

have a nice day.

theres a sensor on the back side of this machine that reads if the belt is stopping in the right position works inside the belt unit accessable from the front of the machine first take out the transfer roller unit and then take out the Image transfer belt check the inside of the belt (clean) the gold plated belt mark. but sense you going to need to do that, vaccum out the hole machine, check Lubricant bars very important no this machine one under drum brush one on the image transfer roller and another in image transfer cleaning unit under the brush. this will be a small PM or a check up. nothing more to add.
