The machine increases the fixing temperature while decreasing the copying/printing speed in a low-temperature environment to ensure fixing on bond paper.

A cassette selected for bond paper is used as the source of paper.

- if the environment temperature is 17 deg C or higher,

the target temperature is 205 deg C (same as normal copying/printing mode)

- if the environment temperature is lower than 17 deg C,

the target temperature is 210 deg C

- the copying/printing speed is 30 cpm/ppm

9.3 Various Control Mechanisms

9.3.1 Fixing Drive System

9.3.1.1 Controlling the Drive of the Fixing Roller

iR5065 / iR 5055 / iR5075 / / /

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 / / /

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.
