MX-3114N OPERATIONAL DESCRIPTIONS 13 – 40
Signal name Name Function/Operation
1TC (CMY) Primary transfer voltage (CMY) Flows the transfer current to the primary transfer belt, and transfers toner images from the OPC drum to
the transfer belt.
1TC (K) Primary transfer voltage (K) Flows the transfer current to the primary transfer belt, and transfers toner images from the OPC drum to
the transfer belt.
1TUD_CL Transfer mode detector (CL) Detects separation of the transfer belt and the transfer mode. (Detection is made by combination of
1TUD_CL/1TUD_K signals.)
1TUD_K Transfer mode detector (BK) Detects separation of the transfer belt and the transfer mode. (Detection is made by combination of
1TUD_CL/1TUD_K signals.)
1TURC_1 Primary transfer separation clutch 1 Controls separation of the primary transfer unit.
1TURC_2 Primary transfer separation clutch 2 Controls separation of the primary transfer unit.
2TC Secondary transfer belt voltage Flows the transfer current to the secondary transfer belt, and transfers toner images from the primary
transfer belt to paper.
2TUD Secondary transfer position detector Detects the position (separation) of the secondary transfer unit.
2TURC Secondary transfer separation clutch Controls separation of the secondary transfer unit.
DVM_K Developing motor (K) Drives the developing/black OPC drum (BK)/transfer section.
PTC PTC voltage High voltage for PTC
No. Name Function/Operation
1 High voltage PWB (TC PWB) Generates the transfer voltage.
2 Cleaning blade Cleans residual toner on the primary transfer belt.
3 Primary transfer belt Transfers toner images of the OPC drum onto the transfer belt.
4 Primary transfer roller (K, C, M, Y) Applies a high positive voltage to the primary transfer belt.
5 Primary transfer belt drive roller Drives the transfer belt. A negative voltage is applied when in the transfer operation, and an alternate
high voltage (positive and negative) is applied when cleaning.
6 Primary transfer belt follower roller Transfer belt follower drive
7 Primary transfer belt tension roller Applies a tension to the transfer belt.
8 PTC opposed roller Flows the PTC current to the GND.
9 Secondary transfer belt Transfers toner images on the primary transfer belt to paper.
10 Secondary transfer roller Connects the secondary transfer belt to the GND, and flows the transfer current.
11 Secondary transfer belt drive roller Drives the transfer belt.
12 Secondary transfer belt follower roller Transfer belt follower drive
13 PTC unit Reduces positive charges on the primary transfer belt, and improves the transfer efficiency.
14 Primary transfer waste toner transport screw Transports waste toner in the primary transfer cleaning unit to the waste toner collection section.
15 PTC cleaner Clean the PTC wire.
16 Separation pawl Separates paper after transfer.
17 Discharge brush Discharges the secondary transfer belt surface after transfer to neutralize it.
