General Troubleshooting
2-Sided Printing Problems
If you have problems when copying or printing on two sides of a sheet, then the
media or the settings you are using are probably not correct.
•
Make sure that you are using approved media. Only plain paper in either
Letter or A4 size are usable in the Duplex Unit.
•
Do not do 2-sided printing on envelopes, labels, postcards, thin or think card
stock, letterhead, or on plain paper with a size other than Letter or A4.
•
Make sure you do not have mixed media types in the tray.
•
In the printer driver Layout tab, under Print on Both Sides, choose
Short Edge
Binding
(flipped as on a clipboard) or
Long Edge Binding
(flipped as in a
loose-leaf notebook).
•
For 2-up on 2-sided pages, choose
Collate
only in the printer driver’s Basic tab.
Do not set collation in the application.
Changing the Duplexing Speed
If you are having problems with image transfer during 2-sided printing or copying,
you can change the duplexing speed.
To change the duplexing speed:
1. On the printer control panel, press the
Back/Menu
button to enter the System
Menu, then press the
Down Arrow
button and go to
General Setup
. Press
OK
.
2. Arrow down to
Duplex Speed
and press
OK
.
3. Select from the following options as your situation requires:
•
Automatic: The printer chooses the processing speed based on
environmental conditions (temperature and humidity).
•
Speed: The printer uses the fastest speed available for the media type
being used.
•
Quality: The printer uses a slower speed for optimal print quality.
4. Press
OK
.
Media-Based Problems
1. Check that the correct type of media is being used; for the correct media types
and weights, see “Media and Tray Specifications” on page 1-15. The customer
should use a quality laser printer paper. The printer may have trouble picking
glossy or overly smooth paper.
2. Inspect the paper for bent, torn, or folded corners.
3. Check the paper path for obstructions or debris.
4. Ensure that the correct media type is set in the Control Panel.
5. Ensure that the paper guides are set correctly.
6. Ensure that the media is a supported type for the tray. See “Media and Tray
Specifications” on page 1-15, for the correct media types, sizes, and weights
for each tray.
7. Load a fresh ream of paper in the tray.
