Registration

Adjustments

This feature allows you to adjust the placement of the image area on the

page. Registration adjustments require that the printer be placed into a

service adjustment mode. Consequently, these adjustments are not

designed to be available to end users. Registration adjustments are

persistent. To adjust the registration,

1 Turn off the printer. Press and hold the

TEST PRINT button and switch

the printer back on. The normal startup sounds will not occur.

Continue to hold the

TEST PRINT button down for 25 seconds, at which

time you will notice a slight slowing of the controller fan.

2 Press the

COLOR SELECT button once. The black toner light will ﬂash

to indicate that you are in the service adjustment mode. In addition,

one of the other toner lights will illuminate steadily. Keep pressing the

COLOR SELECT button until you come to the setting that you want.

3 Using the plus or minus buttons, advance the density gauge to illumi-

nate the LED corresponding to the desired adjustment value. For

leading edge registration adjustment, each step in the gauge is equal to

.012 inch (.3 mm). For the other two adjustments, each step in the

gauge is equal to .017 inch (.425 mm).

4 Press the

ENTER button to engage the setting.

Note: If you want to quickly return the printer to its factory defaults,

press and hold both the plus and minus buttons for at least ﬁve seconds.
