connected to a grounded
power source and is turned
on, the control panel shows
Hewlett Packard with moving
cursors indicating that the
firmware code is loading, and
the main motor rotates for
approximately 45 to 60
seconds. When the firmware
is done loading,  Scanner
bulb warming up might
appear on the control-panel
display, and the scan head
moves back and forth for
10-15 seconds. If you lift the
scanner lid, you will see that
the scanner bulb is lit. Near
the end of this time, the
automatic document feeder
(ADF) motor turns on for
about two seconds.No power due to failed power source,

							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.

							Where to look for jams
Jams can occur in these locations:
●Inside the all-in-one
● In output areas
● In the automatic document feeder (ADF)
● In the automatic duplexer (HP LaserJet 3390/3392 all-in-one)
Find and remove the jam by using  the instructions on the following pages. If the location of the jam is
not obvious, first look inside the all-in-one.
Loose toner might remain in the all-in-one after a jam. This problem typically resolves itself after a
few sheets have been printed.
Print cartridge area
To clear a jam in the print cartridge area, perform the following steps:
CAUTION Do not use sharp objects, such as tweezers or needle-nose pliers, to remove
jams. Damage caused by sharp objects will not be covered by the warranty.
When removing jammed media, pull the jammed  media straight away from the all-in-one.
Pulling jammed media out of the all-in-one at an angle can damage the all-in-one.
1. Open the print-cartridge door, and remove the print cartridge.
HP LaserJet 3390/3392
HP LaserJet 3050 HP LaserJet 3052/3055
CAUTIONTo prevent damage to the print cartridge, minimize its exposure to direct light.
2.On the HP LaserJet 3390/3392 all-in-one, open the rear output door, and then rotate the green
pressure-release levers downward.
