(4) Pressure sequence
1. When the Pressure/Retraction Solenoid /Cleaning Blade (SD3) 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.
(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 (SD3) is
energized to start a pressure/retraction sequence. When the Retraction Position Sensor /
Cleaning Blade (PS6) is then blocked, the Pressure/Retraction Solenoid /Cleaning Blade
(SD3) is deenergized.
