HP 4620 - Manual (Page 98)

Scanner did nothing
• Check the original
Make sure that the original is loaded correctly. For more information, see Load an
original on the scanner glass or Load an original in the automatic document feeder
(ADF).
• Check the printer
The printer might be coming out of Sleep mode after a period of inactivity, which
delays processing a short while. Wait until the printer displays the Home screen.
• Check the HP software
Make sure that the HP software provided with the printer is installed correctly.
If the printer is connected to a network and you are unable to scan from its control
panel to a Windows computer, check that scanning is enabled in the HP software.
From the computer desktop, click Start, select Programs or All Programs, and
then select the folder for the HP printer, followed by the printer. Select Print, Scan
& Fax, and then select Manage Scan to Computer under Scan.
NOTE: Scanning runs as a background process on the computer. If you do not
intend to scan frequently, you can choose to disable it.
Scan takes too long
Check the settings
◦
If you set the resolution too high, the scan job takes longer and results in larger
files. To obtain good results, do not use a resolution that is higher than needed.
You can lower the resolution to scan more quickly.
◦ If you acquire an image through TWAIN, you can change the settings so that the
original scans in black and white. See the onscreen Help for the TWAIN program
for information.
Part of the document did not scan or text is missing
• Check the original
◦
Make sure that you loaded the original correctly. For more information, see
Load an original on the scanner glass or Load an original in the automatic
document feeder (ADF).
◦ If you scanned the document from the ADF, try scanning the document directly
from the scanner glass. For more information, see Load an original on the
scanner glass.
◦ Colored backgrounds can cause images in the foreground to blend into the
background. Try adjusting the settings before you scan the original, or try
enhancing the image after you scan the original.
• Check the settings
◦
Make sure that the scan size specified in the HP scanning software is large
enough for the original that you are scanning.
◦ If you are using the HP printer software, the default settings in the HP printer
software might be set to automatically perform a specific task other than the
one that you are attempting. See the onscreen Help for the HP printer software
for instructions about changing the properties.
