Troubleshoot print-quality problems
This section helps you define 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.
Print-quality checklist
Follow the checklist to solve general print-quality problems.
●
Process a cleaning page to clean the fuser (see
Clean the fuser on page 44).
●
Check the printer driver to make sure that you are using the best available print-quality option (see
the user guide).
●
Try printing with one of the alternative printer drivers. The most recent printer drivers area available
for download from
www.hp.com/go/LJM3027mfp_software or www.hp.com/go/
LJM3035mfp_software.
●
Clean the inside of the device (see
Clean the device on page 40).
●
Check the paper type and quality (see
Media specifications on page 15).
●
Check to make sure that Economode is off in the software.
●
Troubleshoot general printing problems (see
Troubleshoot general printing problems
on page 243).
●
Install a new HP print cartridge, and then check the print quality again. (See the instructions
provided with the print cartridge.)
NOTE If the page is totally blank, check to make sure that the sealing tape is removed from the
print cartridge and that the print cartridge is installed correctly. Newer devices have been
optimized to print characters more accurately. This might result in characters that look lighter or
thinner than you are used to from an older device. If the page is printing images darker than those
from an older device, and you want the images to match the older device, make these changes
in the printer driver: on the Finishing tab, select Print Quality, select Custom, click Details, and
select Print Images Lighter.
