COMPOSITION/OPERATION
D. Pressure sequence
1.
When the Cleaning blade pressure/retraction solenoid (SD5) is energized in the
condition, in which the cleaning blade is retracted from the transfer belt, the pres-
sure cam rotates a half turn. This pushes the lever backward.
2.
When the lever is pushed backward, the cleaning blade is returned. Then, the
cleaning blade is pressed against the transfer belt.

Belt Positioning Sensor
• When development takes place in this machine, the image of each color of toner is
formed on the surface of the transfer belt. The leading edge of the image of each color of
toner must therefore be aligned correctly with each other on the surface of the transfer
belt.
• The position of the transfer belt is detected when the Belt positioning sensor (PS6)
detects detection holes provided in the transfer belt.
• There are two detection holes provided in the transfer belt. The image write start position
is varied according to the media size. For a media size of A4 or smaller, the image write
start position is aligned with detection hole A. For a Media size greater than A4, detection
hole B serves as the reference for the image write start position.
