Malfunction
Point to note when replacing the transfer cleaning unit
[Symptom]
When to replace the transfer cleaning unit, it is required to detach the heat absorbing cover [2] from the old unit [1] and attach
the said cover to the new unit [3].
However in service operation a mistake of forgetting to attach the heat absorbing cover occurs from time to time.
If the device is used without attaching the heat absorbing cover, waste toner inside the transfer cleaning unit will cake from the
heat, and this brings failure in toner circulation. Replacing the transfer cleaning unit may be required as a result.
[Service work]
In replacing the transfer cleaning unit referring to the service manual, attach the heat absorbing cover removed from the old unit
[1] to the new transfer cleaning unit.
- Screw [2] x1
- Hook [3] x2
- Boss [4] x2
[Note]
• Do not damage the heat absorbing material [1] attached inside the heat absorbing cover. In case the heat absorbing material
[1] is damaged, do not use the same heat absorbing cover.
• Do not leave the detached heat absorbing cover under a high temperature environment of 50 degrees C or more. The shape
of the heat absorbing cover may be deformed and become unable to be reused.
If needed, prepare the heat cover (FM1-M165-000) that is newly assigned as service part, detach the heat absorbing cover from
the heat cover (FM1-M165-000) and attach it to the transfer cleaning unit.
