Installation of Machine and Storage of Drum

Avoid installing the machine in such places where it may be subjected to high temperature,

high humidity, chemicals and their fumes.

Do not leave drums in a bright place for a long time, otherwise the drum will fatigue and will

not produce sufficient image density immediately after being installed in the machine.

However, this effect may decrease as time elapses.

Cleaning the Drum

At periodic maintenance calls, wipe clean the entire surface of the drum using the designated

cleaning cotton or soft pad. Use sufficiently thick cleaning cotton so as not to scratch the

drum surface inadvertently with your fingertips or nails. Also, remove your ring and wrist-

watch before starting cleaning work to prevent accidental damage to the drum.

Be sure not to use other organic solvents or silicone oil as they will have an undesirable effect

on the drum.

Repairing Scratches on OPC Surface

If a scratch exists on the OPC surface through which the aluminium substrate can be seen,

no copy image will be produced on this area and, in addition, the cleaning blade will be

damaged so replacement with a new drum will be necessary.

Collecting Used OPC Drums

For disposition of used OPC drums, it is recommended to proceed according to the corre-

sponding regional environmental regulations.

Checking and Replacing Cleaning Felt Roller

(1) Precautions for Handling

Never allow solvents such as thinner, etc. to adhere to the cleaning felt roller.

(2) Poor Heat-Roller Cleaning and Countermeasures

Poor heat-roller cleaning should be judged by the deposited toner on the roller. When the felt roller

has heavy toner deposits, the heat-roller surface may be stained with toner. If this happens, re-

place the cleaning felt roller.

The cleaning felt roller will be gradually degraded due to subjection to the heat from the heat roller

over a long period of time; therefore, replace it preferably after about 60,000 copies have been

made.
