Loose toner
Loose toner, in this context, is defined as toner that can be rubbed off the page.
1 If paper is heavy or rough, open the Configure Device menu at the printer control panel. On
the Print Quality submenu, select FUSER MODES, and then select the paper type you are
using. Change the setting to HIGH 1 or HIGH 2, which helps the toner fuse more completely
onto the paper. (See “FUSER MODES” on page 160.) You must also set the type of paper
for the tray you are using. (See “Printing by type and size of paper (locking trays)” on
page 48.)
2 If you have observed a rougher texture on one side of your paper, try printing on the
smoother side.
3 Make sure that the environmental specifications for the printer are being met. (See “Printer
specifications” on page 193.)
4 Make sure that type and quality of the paper you are using meet HP specifications. (See
“Paper specifications” on page 182.)
5 Maintenance might be due. Check this by printing a copy of the supplies status page. (See
“Supplies status page” on page 85.) If maintenance is due, order and install the printer
maintenance kit. (See “Performing preventative maintenance” on page 91.)
