Step two: Check the environment
The environment can directly aect print quality and is a common cause for print-quality or paper-feeding
issues. Try the following solutions:
●
Move the printer away from drafty locations, such as open windows or doors, or air-conditioning vents.
●
Make sure the printer is not exposed to temperatures or humidity outside of printer specications.
●
Do not place the printer in a conned space, such as a cabinet.
●
Place the printer on a sturdy, level surface.
●
Remove anything that is blocking the vents on the printer. The printer requires good air ow on all sides,
including the top.
●
Protect the printer from airborne debris, dust, steam, grease, or other elements that can leave residue
inside the printer.
Try a dierent print driver
Try a dierent print driver when printing from a software program and the printed pages have unexpected lines
in graphics, missing text, missing graphics, incorrect formatting, or substituted fonts.
Download any of the following drivers from the HP Web site: www.hp.com/support/ljm11-m13.
HP PCLmS driver
●
Provided as the default driver on the printer CD. This driver is automatically installed
unless you select a dierent one.
●

●

users
●

Check the EconoMode settings
HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might
outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable,
consider replacing the toner cartridge.
NOTE: This feature is available with the PCL 6 print driver for Windows. If you are not using that driver, you can
enable the feature by using the HP Embedded Web Server.
