2. DESCRIPTION OF OPERATION

outline of density correction

The density is corrected by reading the correction pattern that is printed on the belt with the

density sensor located inside the sensor shutter under the belt unit.

Automatic start timing of density correction:

• At power-on

• When the ID count after the previous correction exceeds 500

A correction error may be issued due to an inadequate toner amount of the pattern

generated, a sensor stained with toner, deficient opening/closing of the shutter, or for other

reasons.

However, even if an error is issued, it is not indicated on the operator panel. Therefore,

forcible density correction will have to be performed in the self-diagnostic mode (section

5.3.2.7) to check the error indication.
