HP Officejet 4314 All-in-One Printer - Manual (Page 110)

The automatic document feeder picks up too many pages or none at all
Cause The separator pad or rollers inside the automatic document feeder might
need to be cleaned. Pencil lead, wax, or ink can build up on the rollers and
separator pad after extensive use, or if you copy handwritten originals or originals
that are heavy with ink.
●
If the automatic document feeder does not pick up any pages at all, the
rollers inside the automatic document feeder need to be cleaned.
● If the automatic document feeder picks up multiple pages instead of single
sheets, the separator pad inside the automatic document feeder needs to be
cleaned.
Solution Load one or two sheets of unused plain white full-size paper into the
document feeder tray and press Start Black . As the plain paper passes through
the automatic document feeder, the paper releases and absorbs residue from the
rollers and separator pad.
Tip If the automatic document feeder does not pick up the plain paper,
try cleaning the front roller. Wipe the roller with a soft lint-free cloth
dampened with distilled water.
If the problem persists, or the automatic document feeder does not pick up the
plain paper, you can clean the rollers and separator pad manually.
To clean the rollers or separator pad
1.
Remove all originals from the document feeder tray.
2. Lift the automatic document feeder cover (1).
This provides easy access to the rollers (2) and separator pad (3), as shown
below.
1 Automatic document feeder cover
2 Rollers

3. Lightly dampen a clean lint-free cloth with distilled water, then squeeze any
excess liquid from the cloth.
