MX-7000N  TRANSFER SECTION  M – 2
2. Operational descriptions
A. Outline
In this section, a high voltage are applied to the primary transfer
roller, toner images on the OPC drum are transferred to the primary
transfer belt surface, 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 (BLTCL) 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.
All pressure contact
All separation
Only black contact
Also performs all pressure contact, all separation, and only black
contact by the roller separation sensor (TBLTC, TBLTB) and the
separation detection arm.
The primary transfer and the secondary transfer are driven together
with the black developing motor.
C. Transfer belt separation
Transfer belt is separated by the transfer separation motor.
The transfer belt is in contact with the OPC drum except for the fol-
lowing cases.
[Case where the transfer belt is not contact with the OPC drum]
• When executing process control (to prevent against breakage of
toner patch on the OPC drum)
• When a jam occurs (Protection of the OPC drum, right door
open/close)
