MX3500N TRANSFER SECTION L – 2
2. Operational descriptions
A. Outline
In this section, a high voltage is applied to transfer images to the
primary transfer belt and toner images on the primary transfer belt
are transferred to paper by the secondary transfer belt.
B. Primary transfer roller separation mechanism
and content
The primary transfer roller performs all pressure contact, all sepa-
ration, and only black contact depending on the operation mode.
When the roller separation clutch (1TURC) is turned ON, the trans-
fer cam rotates and the primary transfer link and the primary trans-
fer arm which is linked with the cam are shifted in the arrow
direction, performing separation of the roller.
The arm performs all pressure contact, all separation, and only
black contact.
The primary transfer and the secondary transfer are driven together
with the black developing motor.
