The following shows the construction of the mechanisms used to control the drive of the fixing roller:
FR_M_CLK: fixing motor clock signal
FSR_M_BRAKE: fixing motor brake signal
FSR_M_ON: fixing motor drive signal
FSR_M_LD: fixing motor drive lock signal
[1] Fixing roller
M3: fixing motor
DCON: DC controller PCB
DC POWER: DC power supply PCB
ERROR CODE:
E014 (fixing motor error)
0000 After the fixing motor has gone on, the machine does not detect the phase lock signal for the fixing motor for 2 sec or more.
9.3.1.2 Controlling the Drive of the Fixing Inlet Guide
iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
The machine controls the height of the fixing inlet guide to suit the type and size of paper being in use, thus preventing the trailing edge of paper from snapping up,
rubbing, or wrinkling.
The following shows the mechanisms associated with the drive of the fixing inlet guide.
