HP Officejet Pro 8600 - Manual (Page 115)

Documents are missing or faded
• Check the media
The media might not meet Hewlett-Packard media specifications (for example,
the media is too moist or too rough). For more information, see Media
specifications.
• Check the settings
The quality setting of Fast (which produces draft-quality copies) might be
responsible for the missing or faded documents. Change to the Normal or Best
setting.
• Check the original
◦
The accuracy of the copy depends on the quality and size of the original.
Use the Copy menu to adjust the brightness of the copy. If the original is
too light, the copy might not be able to compensate, even if you adjust the
contrast.
◦ Colored backgrounds might cause images in the foreground to blend into
the background, or the background might appear in a different shade.
◦ If you are copying a borderless original, load the original on the scanner
glass, not the ADF. For more information, see Load an original on the
scanner glass.
◦ If you are copying a photo, be sure to load it on the scanner glass as
indicated by the icon on the scan bed.
Size is reduced
• The reduce/enlarge or other copy feature might have been set from the printer
control panel to reduce the scanned image. Check the settings for the copy job to
make sure that they are for normal size.
• The HP software settings might be set to reduce the scanned image. Change the
settings, if needed. See the onscreen Help for the HP software for more
information.
Copy quality is poor
• Take steps to improve the copy quality
◦
Use quality originals.
◦ Load the media correctly. If the media is loaded incorrectly, it might skew,
causing unclear images. For more information, see Load media.
◦ Use or make a carrier sheet to protect your originals.
• Check the printer
◦
The scanner lid might not be closed correctly.
◦ The scanner glass or lid backing might need cleaning. For more information,
see Maintain the printer.
◦ The automatic document feeder (ADF) might need cleaning. For more
information, see Maintain the printer.
• Print a Print Quality Diagnostic Page and follow the instructions on the page to
resolve poor quality copy problems. For more information, see Print quality
troubleshooting.
