(7) Separation
• At the transfer process, the sheet of paper
becomes temporarily attached to the drum
due to static electricity. The separation pro-
cess separates the paper from the drum.
• Method: A negative
to the separation charger.
The negative charge on the paper
is decreased.
The electrostatic attraction be-
tween the paper and the drum
weakens.
The paper is separated from the
drum by its own weight.
Output is controlled as follows to obtain satis-
factory separability and transferability.
Position of Paper in Relation to Transfer Point
Leading edge
Trailing edge
Reference
• Combined use of separation charger and sepa-
ration claw.
To prevent the copy paper from failing to be
separated during the operation, due to incom-
plete transfer charging, incomplete separation
charging, or absorption of moisture, and thus
jamming up the cleaner, a separation claw me-
chanically separates any copy paper which
fails to be separated.
