FIXING DRIVE SYSTEM

A. Controlling the Speed of the Fixing Roller
The copier controls its fixing at one of two speeds to ensure good fixing performance for all
types of transfer media (plain paper, transparency).
The fixing motor starts to rotate when the drive signal (FXMON) goes '1', and its speed is
switched based on the combination of the states of the speed switch signals (FXMSP0, FXMSP1).
E014
This code is indicated if the speed of rotation of the fixing motor deviates from
a specific value and the motor clock signal (FXMLK) goes '0'.
To prevent deformation otherwise caused by pressure, the fixing roller is rotated for about 0.6
sec at low speed (75 mm/sec) at intervals of 30 min after it has stopped rotating (in standby state).
