Preventing problems
The following are a few simple steps you can take to improve copy quality:
●Use quality originals.
●Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear
images and problems with the OCR program. See 
Loading originals to copy for
instructions.
●If your device frequently feeds more than one page at a time, the separation pad might
need to be replaced. Contact HP. See the support flyer that came with your device for
information about contacting HP.
●Use or make a carrier sheet to protect your originals.
Note
Recurring feed problems indicate the copier/separation pad is worn. See Ordering HP parts
and accessories to order a new separation pad.

							Scanned image is of poor quality
Is the original a second-generation photo or picture?
Reprinted photographs, such as those in newspapers or magazines, are printed by using tiny
dots of ink that make an interpretation of the original photograph, which dramatically
decreases the quality. Often, the ink dots form unwanted patterns that can be detected when
the image is scanned, printed, or appears onscreen. If the following suggestions do not solve
your problem, you might need to use a better-quality version of the original.
●To eliminate the patterns, try reducing the size of the image after scanning.
●Print the scanned image to see if the quality is better.
●Make sure that your resolution and color settings are correct for the type of scan job that
you are performing. See 
Scanner resolution and color for more information.
Is the image quality better when the document is printed?
The image that appears on the screen is not always an accurate representation of the quality
of the scan.
●Try adjusting your computer monitor settings to use more colors (or levels of gray).
Typically, you make this adjustment by opening Display in Windows Control Panel.
●Try adjusting the resolution and color settings in the scanner software. See 
Scanner
resolution and color for more information.
Is the image skewed (crooked)?
The original might have been loaded incorrectly. Be sure to use the media guides when you
load the originals into the automatic document feeder (ADF). See 
Loading originals to scan for
more information.
Does the scanned image show blotting, lines, vertical white
stripes, or any other defect?
If the scanner is dirty, the image that it produces does not have optimum clarity. See Cleaning
the outside of the device for instructions.
Do graphics look different from the original?
The graphics settings might not be suitable for the type of scan job that you are performing.
Try changing the graphics settings. See 
Scanner resolution and color for more information.

							Part of the image did not scan
Was the original loaded correctly?
Make sure that you loaded the original correctly. See Loading originals to scan for
instructions.
Does the original have a colored background?
Colored backgrounds can cause images in the foreground to blend into the background. Try
adjusting the settings before you scan the original or enhancing the image after you scan the
original. See 
Scanner resolution and color for more information.
Are text or images on the back of a two-sided original
appearing in the scan?
Two-sided originals can bleed text or images from the back side to the scan if the originals
are printed on media that is too thin or too transparent.
Is the original longer than 381 mm (15 inches)?
The maximum scannable length is 381 mm (15 inches) when you use the automatic
document feeder (ADF). If the page exceeds the maximum length, the scanner stops. (Copies
can be longer.)
CAUTION
Do not try to pull the original from the ADF; you might damage the scanner or your original.
See 
Media jams occur in the automatic document feeder (ADF) for instructions.
Is the original too small?
The minimum size that the automatic document feeder (ADF) supports is 51 by 89 mm (2 by
3.5 inches). The original might be jammed. See 
Media jams occur in the automatic document
feeder (ADF) for instructions.
Is the media size correct?
In Scan settings, make sure that the input media size is large enough for the document that
you are scanning. See 
Scanner resolution and color for more information.
ENWW Part of the image did not scan107
 
						

							The scan takes too long
Is your resolution or color level set too high?
If you set the resolution and color level too high, the scan job takes longer and results in
larger files. To obtain good results when scanning or copying, it is important that you use the
correct resolution and color level settings for your job. See 
Scanner resolution and color for
more information.
Is your software set to scan in color?
The system default is color, which takes longer to scan even when scanning a monochrome
original. If you acquire an image through TWAIN or WIA, you can change the settings so that
the original scans in grayscale or black-and-white. See the device software Help for details.
Did you send a print job or copy job before you tried to scan?
If you sent a print job or copy job before you tried to scan, the scan will start if the scanner is
not busy. However, the printer and scanner share memory, which means that the scan might
be slower.
Is your computer set for bidirectional communication?
See the documentation that came with your computer to change the basic input/ouput settings
(BIOS). The recommended bidirectional setting for the parallel port is ECP. The USB
connection is always bidirectional.

							Error messages appear
If one of the following messages appears on the screen, use this information to remedy the
problem.
Common scanning error messages
This section describes common scanning error messages, and how to remedy them. The
most common scanning error messages include the following:
●
Unable to activate TWAIN source
●An error occurred while acquiring the image
●Scanner initiation failed
●Error communicating with scanner
Make sure that you have connected the USB Device Cable (A/B) or IEEE 1284-B-compliant
parallel cable to the correct port on the back of your computer. If you have another port, try
attaching the cable to the other port. Make sure that you have an EPP-(bidirectional) or ECP-
compliant parallel port on your computer. An EPP parallel port is the minimum requirement;
use of an ECP parallel port is strongly recommended. See the documentation that came with
your computer for more information about your port.
Some devices might not share the parallel port with the device. If you have an external hard
drive, or you have a network switchbox connected to the same USB or parallel port as the
device, the other device might be interfering. To connect and use the device, you must
disconnect the other device or you must use two ports on the computer. You might need to
add another parallel interface card. Hewlett-Packard strongly recommends that you use an
ECP parallel interface card. See the documentation that came with your computer for more
information about installing an additional parallel interface card or resolving device conflicts.
Verify that the correct TWAIN source is selected. In the software, check the TWAIN source by
selecting Select Scanner from the File menu.
