    Paper Feed By-pass tray The by-pass paper sensor [A] detects when paper is placed on the tray. The CPU energizes the by-pass clutch [B]. Then the by-pass feed roller [C] starts to feed paper to the registration roller [D] through the relay roller [E]. The by-pass feed roller shaft has two cams Ê, Ë.

    Image Fusing and Paper Exit Fusing Drive The main motor [A] drives the fusing unit through a gear train. Fusing Entrance and Guide Shaft The entrance guide [A] is adjustable for paper thickness to prevent creasing. If creasing occurs frequently in the fusing unit, remove all screws (Ê Ë Ì) and slide the entrance guide to the right.

    6. Details Pressure Roller To change the applied pressure (for example, if the customer complains of insufficient fusing), adjust the position of the pressure springs [B]. The factory setting for the spring position is at the top (minimum pressure). The envelope lever [A] is used by the operator to adjust the size of the gap between the pressure roller and hot roller.

    Image Fusing and Paper Exit New Fusing Unit Detection There are two types of fusing unit: Service part, and Maintenance Kit part. Only the fusing unit in the maintenance kit has the detection mechanism. In the maintenance kit fusing unit, the looped wire on the fusing unit connector contains a fuse [A]. When power is switched on after installing a new fusing unit, the engine board detects the fusing unit through the looped wire.
  • Page 194: Fusing Temperature Control

    6. Details Fusing Temperature Control When the main switch turns on, the CPU turns on the fusing lamp using the soft start process. (The soft start process prevents the room lights from flickering.) The lamp stays on until the thermistor detects the standby temperature.
