Jams
Avoiding jams
Load paper properly
•
Make sure paper lies flat in the tray.
• Do not remove a tray while the printer is printing.
• Do not load a tray while the printer is printing. Load it before printing, or wait for a prompt to load it.
• Do not load too much paper. Make sure the stack height is below the maximum paper fill indicator.
• Do not slide the paper into the tray. Load paper as shown in the illustration.
• Make sure the guides in the tray or the multipurpose feeder are properly positioned and are not pressing tightly
against the paper or envelopes.
• Push the tray firmly into the printer after loading paper.
Use recommended paper
•
Use only recommended paper or specialty media.
• Do not load wrinkled, creased, damp, bent, or curled paper.
• Flex, fan, and straighten paper before loading it.
• Do not use paper that has been cut or trimmed by hand.
• Do not mix paper sizes, weights, or types in the same tray.
• Make sure the paper size and type are set correctly on the Embedded Web Server or the computer.
Note: Depending on your operating system, access the Paper menu using Local Printer Settings Utility or Printer
Settings.
• Store paper according to manufacturer recommendations.
Understanding jam messages and locations
When a jam occurs, a message indicating the jam location and information to clear the jam appears on the printer
display. Open the doors, covers, and trays indicated on the display to remove the jam.
Notes:
• When Jam Assist is set to On, the printer flushes blank pages or pages with partial prints after a jammed page
has been cleared. Check your printed output for blank pages.
