Offsetting
Offsetting is an operation to shift the position of media to be ejected to the stacker media bin so that boundaries
between media units (sets of media, job unit, etc.) can be easily recognized.
Offsetting is executed for staple positions:
•
During front stapling (corner)—Shifts stapled sheets using the front tamper by 20 mm to the rear side
before ejecting them to the stacker media bin.
•
During rear stapling (corner/straight)
–
For media with a width of 216 mm or more [rear staple (corner)]—Shifts stapled sheets using the rear
tamper by 20 mm to the front side before ejecting them to the stacker media bin.
–
For media with a width of less than 216 mm [rear staple (straight)]: shifts stapled sheets using the
front tamper by 9 mm to the rear side before ejecting them to the stacker media bin.
During dual stapling:
•
Shifts stapled sheets using the front tamper by 9 mm to the rear side before ejecting them to the stacker
media bin.
•
Offsetting is not executed (0 mm) for small media.
Functions of compiler unit assembly sensors/motors
•
Sensor (compiler media in)
–
A photo-interrupter to detect whether media is present or not on the compiler unit assembly
–
When media is detected, the actuator leaves the sensing area, which turns the sensor to “H”
(+5 V dc) (light receiving).
•
Sensor (front tamper HP
–
A photo-interrupter to detect the front tamper home position
–
When the front tamper comes to the home position, it enters the sensor’s sensing area, which turns
the sensor to “H” (+5 V dc) (light blocking).
•
Sensor (rear tamper HP)
–
A photo-interrupter to detect the rear tamper home position
–
When the rear tamper comes to the home position, it enters the sensor’s sensing area, which turns
the sensor to “H” (+5 V dc) (light blocking).
•
Front tamper motor
–
A stepping motor to move the front tamper for tamping
–
Clockwise rotation of this motor moves the front tamper to the rear side. Counterclockwise rotation of
this motor moves the tamper to the front side.
