Print Temperature Control

This is a control to set an optimal target temperature to prevent fixing error or high temperature offset. Temperature is controlled

to keep the specified target temperature during printing.

Setting the target temperature

A target temperature is determined according to the paper type/size, time which elapsed from when the last job finished, and

fixing temperature when startup control started.

Down Sequence Control

■ Down Sequence due to the Cartridge Temperature Rise

To prevent the Drum Cleaning Blade from flipping when cartridge temperature rises during continuous paper feed

by estimating the temperature of the cartridge and enter down sequence.

Startup conditions

Enter down sequence stepwise according to the environment temperature and number of continuously printed sheets.

Environment temperature*1

32.5 deg C or more

28 to 32.5 deg C

Lower than 8.5 deg C

Environment temperature*1

32.5 deg C or more

28 to 32.5 deg C

Lower than 28 deg C

*1: It can be checked in the following service mode.

COPIER > DISPLAY > ANALOG > TEMP

*2: Not entering down sequence

*3: Inactive time is approximately 2 minutes

Prevent temperature rise of cartridge by reducing the speed to 1/2 speed or inactive+1/2 speed

To prevent the image on the drum to be affected from a shock which occurs when the trailing edge of the paper pulled by the

Fixing Drive passes through the Registration Roller by constantly creating an optimal arch between the transfer and fixing areas.
