● Do not use paper that has already been run through the MFP.
● Print a few more pages to see if the problem corrects itself.
● Turn over the stack of paper in the tray. Also, try rotating the paper 180°.
● At the MFP control panel, use the PRINT QUALITY menu to decrease the toner density setting
(see Print quality submenu).
● Make sure that the environmental specifications for the MFP are being met (see
Environmental specifications).
● Replace the print cartridge.
Toner smear
Also see Loose toner.
● Print a few more pages to see if the problem corrects itself.

● Make sure that the environmental specifications for the MFP are being met.
● Clean the inside of the MFP and run a manual cleaning page to clean the fuser (see

● Replace the print cartridge.
Loose toner
Loose toner, in this context, is defined as toner that can be rubbed off the page.
● Make sure that the fuser levers are down.
● If paper is heavy or rough, try using a high fuser mode so that toner fuses more completely
onto the paper. At the control panel, use FUSER MODES menu in the PRINT QUALITY submenu
(see Print quality submenu).
● If you have observed a rougher texture on one side of your paper, try printing on the
smoother side.
● Make sure that the environmental specifications for the MFP are being met (see
Environmental specifications).
● Make sure that paper type and quality meet HP specifications (see 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.
