Loose toner
Loose toner, in this context, is defined as toner that can be rubbed off the page.
● If paper is heavy or rough, try using a high fuser mode so that toner fuses more completely
onto the paper. At the printer control panel, use Fuser Modes in the Print Quality menu
(see Print quality submenu).
● If you have observed a rougher texture on one side of your paper, try printing on the non-
rough side.
● Make sure that the environmental specifications for the printer are being met (see
Environmental specifications).
● Make sure that paper type and quality meet HP specifications (see Paper specifications).
● Maintenance might be due. 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.
