							Change jam recovery
This product provides a jam recovery feature that reprints jammed pages.
1. From the Home screen, touch the
Administration  button.  
2.
Open the General Settings  menu, and then
open the  Jam Recovery  menu.  
3. Select one of the following options:
●Auto
 — The product attempts to reprint
jammed pages when sufficient memory is
available. This is the default setting.
● Off — The product does not attempt to
reprint jammed pages. Because no
memory is used to store the most recent
pages, performance is optimal.
NOTE:
When using this option, if the
product runs out of paper and the job is
being printed on both sides, some pages
can be lost.
● On
 — The product always reprints
jammed pages. Additional memory is
allocated to store the last few pages
printed. This might cause overall
performance to suffer.

outlast the mechanical parts in the print cartridge.  If print quality begins to degrade and is no longer
acceptable, consider replacing the print cartridge
If you determine that you need to replace the print ca rtridge, print the supplies status page to find the
part number for the correct genuine HP print cartridge.
