Check paper and the printing environment Step one: Use paper that meets HP specifications Some print-quality problems arise from using paper that does not meet HP specifications. ● Always use a paper type and weight that this printer supports. ● Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, staples, and curled or bent edges. ● Use paper that has not been previously printed on. ● Use paper that does not contain metallic material, such as glitter. ● Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet printers. ● Use paper that is not too rough. Using smoother paper generally results in better print quality. Step two: Check the environment The environment can directly affect 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 specifications. ● Do not place the printer in a confined 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 flow 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. Step three: Set the individual tray alignment Follow these steps when text or images are not centered or aligned correctly on the printed page when printing from specific trays. 1. From the Home screen on the printer control panel, select the Settings menu. 2. Select the following menus: ● Copy/Print or Print ● Print Quality ● Image Registration 3. Select Tray, and then select the tray to adjust. 4. Select Print Test Page, and then follow the instructions on the printed pages. 206 Chapter 9 Solve problems ENWW

Check paper and the printing environment
Step one: Use paper that meets HP specifications
Some print-quality problems arise from using paper that does not meet HP specifications.
Always use a paper type and weight that this printer supports.
Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids,
staples, and curled or bent edges.
Use paper that has not been previously printed on.
Use paper that does not contain metallic material, such as glitter.
Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet
printers.
Use paper that is not too rough. Using smoother paper generally results in better print quality.
Step two: Check the environment
The environment can directly affect 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 specifications.
Do not place the printer in a confined 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 flow 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.
Step three: Set the individual tray alignment
Follow these steps when text or images are not centered or aligned correctly on the printed page when printing
from specific trays.

From the Home screen on the printer control panel, select the
