Automatic Document Feeder Produces a Skewed Copy when Copying Large Stacks of Paper/Media on the Lexmark X65x Series Printers
Overview
On a
Lexmark X65xe series printer
, the paper guides have exhibited a tendency to slide out when scanning from the Automatic Document Feeder (
ADF
) with a large stack of paper. The resulting scanned or copied images print slightly crooked or skewed, as illustrated below.
Exaggerated skew examples
Troubleshooting
The paper guides should be adjusted to set firmly against both long-side edges of the paper. However, they should not be fitted so tightly against the paper that they buckle the sheets. (See images below.)
Guides correctly adjusted
Paper Guides too loose
Paper Guides too tight
NOTE:
 Paper guides loosen with normal usage. They should therefore be adjusted with every scan. Also, improper settings of the ADF guides can lead to

.
Recommended actions:
Before performing troubleshooting steps with the scanner, try printing a
Network Setup
 page to determine which hardware part is causing the issue. To do this:
  • At the
    Ready
     screen, press the
    Menus
    button located in the lower right-hand corner.
  • A list of menu choices will display. Using the Navigation keys, please select
    Reports
    . Another list of menus will then appear in the operator panel. Select
    Network Setup Page
    .
  • The printer will print out one to three pages, (depending on how many network options it has installed). Each of these pages has a border that will help you to see if they exhibit the same skewing issue.
If any of the borders on the
Network Setup
pages appear skewed as well, then an issue exists with a part on the base printer. To view further suggestions on how to correct the issue, refer to the following document: .
If all four borders on the
Network Setup
pages are parallel with the edges of the page, one of the scanner units may require a service action to correct the issue. To determine which unit, please try the steps below:
Check the following
if you are using the ADF scanner:
  1. Do not load different sizes or types of paper at the same time.
  2. Ensure not to overload the ADF input tray
  3. Check and clean the paper feed roller and the separator pad on the ADF.
    NOTE:
     If either of these parts appears worn, they will need to be replaced.
  4. Inspect and clean the felt wiper of the ADF paper feed roller.
  5. If the issue continues after attempting all of the above recommendations, try using the flatbed scanner. When doing so, make sure to properly align the page with the upper-left corner of the scanner glass and fully against the edges.
