HP LaserJet 4250 - Manual (Page 189)

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
Print Quality submenu .) You must also set the type of
paper for the tray you are using. (See Printing by type and size of media (locking trays) .)
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
Operating environment .)
4. Make sure that type and quality of the paper you are using meet HP specifications. (See
Paper specifications .)
5. The printer might be due for maintenance. Check this by printing a copy of the supplies
status page. (See Supplies status page .) If maintenance is due, order and install the
printer maintenance kit. (See Performing preventive maintenance .)
Repeating defects
1. Print a few more pages to see if the problem corrects itself.
2. If the distance between defects is 38 mm (1.5 inches), 55 mm (2.2 inches), or 94 mm
(3.7 inches), the print cartridge might need to be replaced.
3. Clean the inside of the printer and run a cleaning page to clean the fuser. (See Cleaning
the printer .)
4. The printer might be due for maintenance. Check this by printing a copy of the supplies
status page. (See Supplies status page .) If maintenance is due, order and install the
printer maintenance kit. (See Performing preventive maintenance .)
