HP laserjet 3390, 3392 all-in-one サービスマニュアル

If you are experiencing jams in the duplex paper path, make sure that the duplex-tray

lever is set to the correct media size for your country/region. Open the duplex-paper-path door
and look at the embossed arrow on the lever. Make sure that it points to the media size for your
country/region. If the size needs to be changed, push the lever all the way in for duplex printing
on letter- and legal-size media, or pull it all the way out for duplex printing on A4-size media.

Occasionally, paper or other print media can become jammed during a print job. Some causes include
the following events:

●

The print media that is being used does not meet HP specifications.

●

The media is damaged or has 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.

●

The input trays are loaded incorrectly or overfilled, or the media guides are not set correctly.

●

Too many sheets have accumulated in an output area, or sheets are blocking an output area.

●

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.
