Solving image-quality problems
Image-quality issues can be print-quality problems or copy-quality problems. Copy-quality problems can
be separated into ADF copy-quality problems and flatbed glass copy-quality problems. To identify a
print-quality problem, try printing the job from the control panel. If the issue persists, it is probably a print-
quality problem. If there is no longer a problem it is probably a copy-quality issue. To solve copy-image
problems, see
Solve copy-quality problems on page 494.
Solve print-quality problems
This section describes print-quality problems and what to do to correct them. Often print-quality problems
can be handled easily by making sure that the device is correctly maintained, using print media that
meets HP specifications, or running a cleaning page.
If the print- or copy-image defect can be isolated to a scan location, use the tables in this section to
determine the type of defect (for example, blank pages or lines), and then identify the MFP component
that is most likely to cause that type of defect.
Solve copy-quality problems
If the print- or copy-image defect can be isolated to a scan location, use the tables in this section to
determine the type of defect (for example, blank pages or lines), and then identify the MFP component
that is most likely to cause that type of defect.
The following are a few simple steps you can take to improve copy quality:
●
Copy from the flatbed glass. This will produce a higher quality copy than from the ADF.
●
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.
●
Use or make a carrier sheet to protect originals.
NOTE Verify that the media meets HP specifications. See Supported media weights and
sizes on page 444.
Print-quality problems associated with media
Some print-quality problems arise from the use of inappropriate media.
●
Use media that meets HP specifications. See
Supported media weights and sizes on page 444.
●
The surface of the media is too smooth. Use media that meets HP specifications. See
Supported
media weights and sizes on page 444.
●
The moisture content is uneven, too high, or too low. Use media from a different source or from an
unopened ream.
●
Some areas of the media reject toner. Use media from a different source or from an unopened
ream.
●
The letterhead you are using is printed on rough media. Use a smoother, xerographic media. If this
solves your problem, ask the supplier of your letterhead to use media that meets the specifications
for this device. See
Supported media weights and sizes on page 444.
