13. FUSER / EXIT UNIT

13.1 General Description

In the equipment, the fuser unit which fuses toner on the paper and the paper exit section (exit roller)
which outputs the paper with the fused toner to the inner tray are combined together to make up the
fuser/exit unit.
In the fuser unit, toner is fused by applying heat and pressure on the transferred image on the trans-
ported paper. The paper is then transported to the exit tray after the completion of fusing. The fuser/exit
unit is driven by the main motor (M3), and the heat roller and exit roller are rotated by the main motor
(M3).
When the automatic duplexing unit (ADU: optional) is installed, it is driven by the exit motor (M7).
Other than the above rollers, the fuser/exit unit consists of the heater lamps, separation fingers, ther-
mistors (THMS1/THMS2/THMS3), fuser thermostat (THMO1), paper transport guide and the exit sen-
sor which detects the status of the paper transport, etc.
