Theory of operation ver. 2.0 Nov. 2007
(4) Pressure sequence
1. When the pressure/retraction solenoid/cleaning blade is energized in the condition,
in which the cleaning blade is retracted from the transfer belt, the pressure 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.
(5) Home position detection
• The position of the cleaning blade is unknown when the power switch is turned ON or the
cover is opened and closed, the machine performs a home position detection sequence
during a warm-up cycle.
• During the warm-up cycle, the pressure/retraction solenoid/cleaning blade is energized
to start a pressure/retraction sequence. When the retraction position sensor/cleaning
blade is then blocked, the pressure/retraction solenoid/cleaning blade is deenergized.
