3.4 INSTALLING A NEW DRUM

The installation procedure for a new drum is the same as for the

base copier (A109) except the following steps which come after

turning on the main switch.

The steps from 3 to 12 are to apply lubricant to the new drum

surface. These steps can all be replaced by just making 10

copies of the C-4 Test Chart on A3 (11"X17") paper.

If the developer is replaced together with the OPC drum, steps 3

to 12 are unnecessary because lubricant is applied to the drum

surface during the developer initialization.

1. Replace the OPC drum with a new one and reassemble the copier.

2. Turn on the main switch.

3 . Place a few sheets of A3 (11"X17") white paper and close the platen

cover (DJF).

4 . Enter the SP mode and open [2]SP Test, page 1.

5 . Set the Test Pattern Level [A] to " 30 ".

NOTE: If the test pattern level is too high, a lot of toner will be

consumed and toner scattering will occur inside the machine.
