e-STUDIO160/200/250 COPYING PROCESS 3 - 6 December 2002 TOSHIBA TEC
* Output is controlled as follows to obtain satis-
factory separability and transferability.
(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 DC bias is applied
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.
Position of Paper in Relation to Transfer Point Separation Output
Leading edge -4.3 KV DC
Trailing edge -3.9 KV DC
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.
