Factors aecting print performance
Problem Cause Solution
Pages print but, are totally blank. The sealing tape might still be in the toner
cartridges.
Verify that the sealing tape has been
completely removed from the toner
cartridges.
The document might contain blank pages. Check the document that you are printing
to see if content appears on all of the
pages.
The product might be malfunctioning. To check the product, print a Conguration
page.
Pages print very slowly.
NOTE: The product print speed is
eected by various factors (for example,
media size or page complexity).
Heavier media types can slow the print job. Print on a dierent type of media.
Complex pages can print slowly. Proper fusing might require a slower print
speed to ensure the best print quality.
Paper type not set correctly. Select the type to match the paper.
Pages did not print. The product might not be pulling media
correctly.
Ensure paper is loaded in the tray
correctly.
If the problem persists, you might need to
replace the pickup rollers and the
separation pad.
The media is jamming in the product. Clear the jam.
The USB cable might be defective or
incorrectly connected.
●
Disconnect the USB cable at both
ends and reconnect it.
●
Try printing a job that has printed in
the past.
●
Try using a dierent USB cable.
Other devices are running on your
computer.
The product might not share a USB port. If
you have an external hard drive or network
switchbox that is connected to the same
port as the product, the other device might
be interfering. To connect and use the
product, you must disconnect the other
device or you must use two USB ports on
the computer.

speeds or operational pauses between printed pages during normal product operation. Factors that
determine the print speed of the product include the following:
