Changing the Developer Mix

Attention!

You must leave printer power on while you do this task, but the printer should not be printing.

Using the wrong developer mix can cause serious print quality problems; this can force a service call. See Table 15 on page 177 for the correct developer mix part number.

Do this task when you see the following message:

CHANGE DEVELOPER MIX 0788

Note: You do not have to replace developer mix the ®rst time you see the CHANGE

DEVELOPER MIX message. To bypass the message, SELECT the Ready pushbutton on the main Display Touch Screen.

The CHANGE DEVELOPER MIX message reappears each time end-of-forms is reached, or every 4 000 feet of forms thereafter. When 50 000 additional feet of forms have been processed since the message originally appeared, you must change developer mix before you can return the printer to Ready status.
