1.ADDITION CARRIED OUT OF A CASSETTE RELEASE MYLAR SHEET.

2.ADDITION OF SEALANT CARRIED OUT TO THE FUSING THERMOSTAT.

3.CHANGE CARRIED OUT IN THE DAMPING RESISTANCE COEFFICIENT
OF THE PCU PWB.

No. : CLE-052

1. Addition carried out of a cassette release mylar sheet.

1.Model Name: JX-8200 (All destination)

2.General: There have been problems of the revolving plate not being able to be released when

the copy paper cassette is engaged. As a measure to alleviate this problem the action
described below has been carried out.

3.Description: A. Temporary: The addition of a cassette release mylar sheet has been carried out

to the frame base plate until the proper changes were able to be made
in the metal mold.
Cassette release mylar sheet PSHEP4628FCZZ

B. Permanent: A change has been carried out in the metal mold of the frame base plate.

Frame base plate LDAIU0011GCZ2 → LDAIU0011GCZ3

2. Addition of sealant carried out to the fusing thermostat.

1.Model Name: JX-8200 (All destination)

2.General: The addition of the sealant has been carried out as a measure to improve the adhesive

performance of the tape used with the fusing thermostat.

3.Description: The fusing thermostat RDTCT0018GCZ1 → RDTCT0018GCZ2.

Added sealant

4.Action: From 1998 May production.

3. Change carried out in the damping resistance coefficient of the PCU PWB.

1.Model Name: JX-8200 (All destination)

2.General: The damping resistance of the main signal line upper of the drive between the CPU and

the gate array in the PCU PWB has been changed from 10 kΩ to 100Ω. This action has
been carried out as a measure to improve the movement stability of the main motor,
which is controlled by the PCU PWB, and as a measure to improve noise conditions.

3.Description: A change has been carried out in R109 in the PCU PWB from 10 kΩ to 100Ω.

The 10 kΩ resistor VRS-TS2AD103J- → 100Ω resistor VRS-TS2AD101J­PCU PWB CPWBX0089GC57 → CPWBX0089GC62
