Clearing jams
This section contains instructions for clearing jams from the all-in-one.
Causes of jams
Occasionally, paper or other print media can become jammed during a print job. Some causes
include the following events:
● The input trays are loaded improperly or overfilled, or the media guides are not set properly.
● Media is added to or removed from an input tray during a print job or an input tray is removed
from the all-in-one during a print job.
● The cartridge door is opened during a print job.
● Too many sheets have accumulated in an output area, or sheets are blocking an output area.
● The print media that is being used does not meet HP specifications. See Media specifications .
● The media is damaged or has foreign objects attached to it, such as staples or paper clips.
● The environment in which the print media was stored is too humid or too dry. See Printing and
storage environment .
Tips to avoid jams
● Verify that the input tray is not overfilled. The input tray capacity varies depending on the type of
print media that you are using.
● Verify that the media guides are properly adjusted.
● Check that the input tray is securely in place.
● Do not add print media into the input tray while the all-in-one is printing.
● Use only HP-recommended media types and sizes. See Media specifications for more
information about print media types.
● Do not let print media stack up in the output bin. The print media type and the amount of toner
used affect the output bin capacity.
● Check the power connection. Make sure that the power cord is firmly connected to both the all-
in-one and the power supply box. Plug the power cord into a grounded power outlet.
