Solving Stacker Problems
Correcting Miscellaneous Stacker Problems
Some stacker problems may not cause an error message and may not interfere with the operation of
the printer. If you are experiencing one of the problems listed below and there is no error message
shown on the control panel display, refer to the procedures in the following sections to check the
possible causes of the specific problem.
•Inoperative stacker
• Erratic operation
•Unusual noise
Inoperative Stacker
The following characteristics define this feeder problem:
• The stacker appears to be inoperative.
• When attempting to print to the stacker, the stacker does not respond and does not transport
paper.
• The control panel does not display an error code.
The following procedure guides you through multiple actions that may solve this stacker problem.
Proceed one step at a time until the problem is solved—you may not need to complete the entire
procedure. If one of the steps in this procedure corrects the problem but the identical problem
returns in less than 50 prints, call for service.
1. Open and then firmly close all of the printer and stacker doors and covers.
Interlock switches monitor the position of printer doors and covers. When a door is closed,
the interlock switch is activated and the stacker can operate. When a door is open, the inter-
lock switch is not activated and the stacker cannot operate. If a door is not firmly closed, the
interlock switch may not be fully activated—resulting in an inoperative stacker.
2. Examine the printer driver settings to make sure the stacker is available as an installed option.
If the stacker is correctly set as an installed option, reload the printer driver software.
The printer driver software running on the host computer may be damaged. Reinstalling the
software is an easy and inexpensive way to isolate or eliminate the problem. Refer to the
DRIVERS folder on the Electronic Library CD-ROM for detailed instructions on installing
the driver.
3. Call your service technician.
This problem may be caused by a malfunctioning or broken component that requires service.
