• Code: C13C8
• Description: New Transfer Belt Unit resetting failure
  The output from the new unit detecting terminal remains HIGH and the copier does not recognize that a new unit has been installed. 1. After an image stabilization sequence is completed, the fuse blowout signal of the new unit is set to a blowout state. 2. After the lapse of 2 sec. after step 1, the fuse blowout signal is brought to a state where no new units are installed. 3. After the lapse of 0.1 sec. after step 2, a new unit check sequence is carried out. A total of three cycles of steps 1 to 3 are carried out and, if the copier fails to detect a new unit a third time, a malfunction condition results.
• Remedy: 1 Each unit is installed properly in the copier (good contact connection). YES: Change Master Board. NO: Reinstall.

• Code: C13CA
