Transfer Unit Detection and New Unit Detection
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.
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 any 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.
NOTE: The transfer belt unit is replaced as a maintenance item.
