Minimizing Paper Jams
This section provides information to help you minimize paper jams.
Make sure to:
• Use only supported media. For more information see Supported Media on page 53.
• Set the tray settings on the control panel to the loaded media size and type.
• Load the media flat, especially on the leading edge.
• Install the printer on a hard, flat, level surface.
• Store media in a dry location.
• Remove transparencies from the output tray immediately after printing to avoid static buildup.
• Adjust the media guides in trays after inserting the media. A guide that is not properly adjusted 
can cause poor print quality, media misfeeds, skewed prints, and printer damage.
Avoid the following:
• Media that is folded, wrinkled, or excessively curled.
• Fanning transparencies because this causes static.
• Loading more than one type/size/weight of media in a tray at the same time.
• Overfilling the trays.
• Allowing the output tray to overfill.
• Allowing the output tray to fill with more than a few transparencies.
Troubleshooting Paper Jams
This section includes:
•Multiple Sheets are Pulled Together on page 162
•Paper Jam Message Stays On on page 163
•Media Misfeeds on page 163
The printer is designed to function with minimal paper jams using Xerox supported media. Other 
media types may cause more frequent paper jams. If supported media is jamming frequently in one 
area, that area may need to be cleaned or repaired.
Multiple Sheets are Pulled Together
Probable CausesSolutions
The paper tray is too full. Remove some of the paper. Do not load paper past 
the fill line. For details, see Loading Media on 
page 56.
The front edges of the paper are not even. Remove the paper, align the front edges, then reload 
it.

Paper Jam Message Stays On
Media Misfeeds
The paper is moist from humidity. Remove the damp paper from the tray and insert 
new, dry media into the tray.
Too much static electricity is present. Try a new ream of paper. Do not fan transparencies.
Probable CausesSolutions
Some paper remains jammed in the printer. Recheck the paper path and make sure that you have 
removed all of the jammed paper, including any 
small pieces that may have become stuck. Open and 
close the printer doors and verify that all doors are 
properly closed.
Probable CausesSolutions
The media is not correctly positioned in the tray. Remove the misfed media and reposition the media 
properly in the tray. Ensure that the media guides in 
the tray are set correctly.
The number of sheets in the tray exceeds the 
maximum sheets allowed.Remove the excess media so that there is no media 
above the fill line. For details, see Loading Media on 
page 56.
The media guides are not correctly adjusted to the 
media size.Adjust the media guides in the tray to match the size 
of the media.
Warped or wrinkled media is loaded in the tray. Remove the media, smooth it out, then reload it. If it 
still misfeeds, do not use that media.
The media is moist from humidity. Remove the moist media and replace it with new, dry 
media.
Unsupported media (wrong size, thickness, type, etc.) 
is being used.Verify that you are using media supported by the 
print job and the tray you are printing from.

Using Color Sampler Pages
The color sampler pages are designed to help you select colors to use in your print jobs. Each sampler 
page lists either the percentages of ink used (CMYK), or the amounts (from 0 to 255) of red, green, and 
blue that are used. Most application software allows you to select colors by setting the RGB, CMYK, and 
PANTONE values. The Sampler Pages help you set or match specific colors by showing what colors you 
get for different color values. This is useful for matching specific colors, hues, and gradients for graphic 
arts and office applications.
Notes:
•Since pages can be color corrected, be sure that the color correction setting used for 
printing the color sampler pages is the same as the color correction setting selected in 
the printer driver. Driver settings much match the setting set on the printer control panel 
in order to match the target color.
•Before printing the sampler pages, select the appropriate default print-quality mode and 
color correction from the Printer Setup menu on the control panel. Color correction for 
Sampler pages can also be set in CentreWare IS. For details, see the CentreWare IS 
online help.
•The color sampler pages are for use with the PostScript driver only.
To print color sampler pages from the printer control panel:
1. Select the default print-quality mode and color correction you are trying to match for the 
PostScript driver. For details, see Selecting a Print-Quality Mode on page 165.
2. Select Information and then press the OK button.
3. Select Sample Pages > OK.
4. Select the desired color sampler page and then press OK.
Note:Each color sampler page prints a multiple-page chart. To stop printing before all pages of a 
chart are printed, press the Cancel button on the control panel.
