(2) Check the life of the consumables (particularly the drum, developer material and transfer belt unit) and
replace them, if necessary.
• When replacing any consumable, use steps (a) to (c) below.
(a) Enter PM support mode. Reset the counter corresponding to the replaced consumable to "0."
* For further information regarding PM support mode, refer to the Service Handbook.
(b) Enter adjustment mode [05]. Select code [396]. Press the [START] button.

(c) Perform the automatic calibration.
* For further information regarding the procedures, refer to procedure (2) in 1.1 To Obtain a Darker
Image.
* After replacing any consumable, remember to reset the counter corresponding to it to "0." Otherwise, it
may cause a loss in copier performance, including degradation in the image quality and reduction in the
life of the consumables.
* While replacing any consumable, also check the slit glass in the laser optical unit, and thoroughly clean it,
if it is soiled.
Cautions after the completion of the adjustment
Switching image quality control mode will increase the warm-up time by approximately 25 seconds at maximum,
immediately after the copier is turned on or returned from energy saving mode. In addition, it will increase the
interval during which image quality control is performed. This may possibly shorten the life of the consumables.
Pay special attention to these factors and perform the adjustment, while checking the image quality.
Remarks
When replacing any consumable, refer to the relevant information in the Service Manual and Service Handbook.
