6.7.2 TRANSFER UNIT DETECTION AND NEW UNIT

Transfer belt unit detection:

The transfer belt unit is detected when the connector [A] is connected.

The transfer belt rotation sensor [B] detects when the transfer belt entrance roller turns. It

also detects the belt speed. To do this, it monitors the black and white stripes on the shaft.

If the sensor detects that the rotation speed is out of specification, the machine shows

Changes in temperature have an effect on the transfer belt drive roller. This can cause

changes in belt speed. Color registration errors occur if belt speed is not constant. The

rotation sensor detects the speed change and the machine keeps the transfer belt speed

constant. You can enable or disable this belt speed correction with SP 2153 8.

New transfer belt unit detection:

The transfer belt rotation sensor has a fuse when the transfer belt unit is new. The fuse is

blown when the machine is turned on. At this time, it is detected as a new unit.
