TECHNICAL BULLETIN
Increase of margin for "H4 trouble

1. Model Name 2. Symptom

AR-M256/M316 Since the rate of thermal expansion of the fusing unit varies depending on the material, looseness is given to the lamp fixing plate mounting the fusing upper frame (resin) and heater lamp (glass). However, if the looseness of the lamp fixing plate is small, the expansion difference between fusing upper frame and heater lamp cannot be absorbed, and disconnection may occur at the connection section of the heater lamp sealing section. It causes H4 trouble.

3. Description

The size of the lamp fixing plate has been changed from 24.00 mm to 23.7 mm to increase the margin for H4 trouble by increasing the looseness of the fusing upper frame and lamp fixing plate.

4. Action

Executed from the production in August, 2007
