HP laserjet 3390, 3392 all-in-one Manuale Di Servizio

The following are a few simple steps you can take to improve copy and scan quality.

●

Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan.

●

Use high-quality originals.

●

Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear
images. See 

 for instructions.

●

Adjust the software settings according to how you plan to use the scanned page.

●

If your all-in-one frequently feeds more than one page at a time, you might need to replace the
separation pad. See 

.

●

Use or make a carrier sheet to protect your originals.

Blank pages

The original might have been loaded
upside down.

In the automatic document feeder (ADF),
put the top end of the stack of originals
into the ADF input tray, with the media
stack face-up and the first page to be
scanned on top of the stack.

On the flatbed scanner, place the original
document face-down with the upper-left
corner of the document at the lower-right
corner of the glass.
