ProblemCauseSolution
The scanned image is of poor
quality.The original might be a second-generation
photo or picture.●
To eliminate the patterns, try reducing
the size of the image after scanning.
● Print the scanned image to see if the
quality is better.
● Verify that the resolution settings are
correct for the type of scan job that you
are performing. See 
Scannerresolution and color on page 107
.
● For best results, use the flatbed
scanner for scanning rather than the
automatic document feeder (ADF).
The image that appears on the screen might
not be 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 settings in
the scanner software. See

Part of the image did not scan.The original might have been loaded
incorrectly.Load the original on the flatbed glass or use
the media guides when you load the
originals into the ADF. See 
Load originals forscanning on page 98.
A colored background might be causing
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.
The original is longer than 381 mm (15
inches).The maximum scannable length is 381 mm
(15 inches) when you use the automatic
document feeder (ADF) input tray. 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 
Clear jams

The original is too small.The minimum size that the flatbed scanner
supports is 25 x 25 mm (1 x 1 inch). The
minimum size that the ADF supports is 127
x 127 mm (5 x 5 inches). The original might
be jammed. See 
Clear jams from the ADF
on page 215.
The media size is incorrect.In Scan  settings, make sure that the input
media size is large enough for the document
that you are scanning. .
The scan takes too long The resolution is set too high.Change the resolution settings to the correct
settings for your job. See Scanner resolutionand color on page 107 .
The software is 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 product software Help for details.
A print job or copy job was sent before you
tried to scan.If someone sent a print job or copy job before
you tried to scan, the scan will start if the
scanner is not busy. However, because the
product and scanner share memory, the
scan might be slower.
The scanning PC may not have enough
available resources.Close unused applications on the PC. If the
scan is still too slow, try rebooting the
scanning PC.
Antivirus, antispyware, or firewall software
on the scanning PC may slow scanning. Consult your antivirus, antispyware, or
firewall software documentation.

Scan-quality problems
Prevent scan-quality problemsThe 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 
Load paper and print media on page 59
 for instructions.
● Adjust the software settings according to how you plan to use the scanned page. See 
Scanner
resolution and color on page 107
 for more information.
● If your product frequently feeds more than one page at a time, the separation pad might need to
be replaced. Contact HP. See 
www.hp.com/support/CM2320series
 or the support flyer that came
in the product box.

Optimize and improve image quality
Print-quality checklist
General print-quality problems can be solved by using the following checklist:
1. Make sure that the paper or print media that you are using meets specifications. See 
Paper and
print media on page 53. Generally, smoother paper provides better results.
2. If you are using a special print media such as labels, transparencies, glossy, or letterhead, ensure
that you have printed by type.
3. Print a configuration page and supplies status page at the product control panel. See 
Information
pages on page 168.
◦ Check the supplies status page to see if any supplies are low or empty. No information is
provided for non-HP print cartridges.
◦ If the pages do not print correctly, the problem is with the hardware. Contact HP. See
www.hp.com/support/CM2320series
 or the support flyer that came in the product box.
4. Print a demo page from HP ToolboxFX. If the page prints, the problem is with the printer driver.
Try printing from another printer driver. For example, if you are using the PCL 6 printer driver, print
from the PS printer driver.
◦Use the Add Printer Wizard in the 
Printers (or Printers and Faxes  in Windows XP) dialog
box to install the PS driver.
5. Try printing from a different program. If the page prints correctly, the problem is with the program
from which you were printing.
6. Restart the computer and the product and try printing again. If the problem is not resolved, see
General print quality issues on page 219.
Manage and configure printer drivers
Print-quality settings affect how light or dark the print is on the page and the style in which the graphics
are printed. You can also use the print-quality settings to optimize the print quality for a specific media
type.
You can change the settings in the product properties to accommodate the types of jobs that you are
printing. The following settings are available, depending on the printer driver that you are using:
● 600 dpi
● Custom:
 This setting produces the same resolution as the default setting, but you can change the
scale patterns.
NOTE: Changing the resolution can change the formatting of your text.
Temporarily change print-quality settings
To change the print-quality settings only for the current software program, open the properties through
the Print Setup  menu in the program that you are using to print.

Network problems
Verify that the product is on and online
Check the following items to make sure the product is ready to print.
1.Is the product plugged in and turned on?
Make sure that the product is plugged in and turned on. If the problem persists, you might have a
defective power cable, power source, or product.
2. Is the product  Ready light on?
If the light is blinking, you might need to wait until the current job is completed.
3. Is the product control-panel display blank?
●Make sure the product is turned on.
● Make sure the product is installed correctly.
4. Does a message other than  Ready appear on the product control-panel display?
● See your product documentation for a complete list of control panel messages and corrective
actions.
Resolve communication problems with the network
Check the following items to verify that the product is communicating with the network. This information
assumes you have already printed a network configuration page (see 
Information pages
on page 168
).
1. Are there any physical connection problems between the workstation or file server and the product?
Verify that the network cabling, connections, and router configurations are correct. Verify that the
network cable lengths meet network specifications.
2. Are the network cables connected properly?
Make sure that the product is attached to the network using the appropriate port and cable. Check
each cable connection to make sure it is secure and in the right place. If the problem continues,
try a different cable or ports on the hub or transceiver. The amber activity light and the green link
status light next to the port connection on the back of the product should be lit.
3. Are the product link speed and duplex settings set correctly?
Hewlett-Packard recommends leaving this setting in automatic mode (the default setting).
4. Can you ping the product IP address?
Use the command prompt to ping the product from the computer. For example:
ping 192.168.45.39
Ensure that the ping displays round-trip times.
If you are able to ping the product, verify that the IP address configuration for the product is correct
on the computer. If it is correct, delete and then add the product again.
