Using This Control: Does This:
Vacuum Push Button

r4co0118

Turns the vacuum on or off in the fuser area.

The vacuum holds the forms against the preheat platen, which partially fuses the toner to the forms. The Vacuum-Off Warning Indicator is to the right of the vacuum push button. This indicator comes on to warn you that the forms-path vacuum is off.

Puller Lever, Release

r4co0114

Releases pressure on the scuff and backup rollers inside the fuser area. To release these rollers, move and hold the puller lever to the release position.
Puller Lever, Printing

r4co0113

Applies pressure to the scuff and backup rollers inside the fuser area during the printing process. The lever is spring loaded in this position, so pressure is normally applied to the scuff and backup rollers.
Puller Run Button

ic3u0008

Turns the puller rolls on for five seconds.
Stack Height Adjustment

r4co0242

Adjusts the height of the printed forms. Note that as you reduce the stack height, the forms stack is lighter, but you must empty the stacker more often.

To adjust the stack height:

  1. Loosen the knob by turning it counterclockwise.
  2. Position the knob next to the desired stack height.
  3. Tighten the knob by turning it clockwise.
Note:
Use this control only for fan-fold forms, not for roll-feed forms.
