Loose toner Loose toner, in this context, is defined as toner that can be rubbed off the page. 1. If the paper is rough, and the toner easily rubs off, open the Print Quality menu at the device control panel. Open the Fuser Modes submenu and then select the paper type that you are using. Change the setting to HIGH 1 or HIGH 2, which helps the toner fuse more completely onto the paper. See the user guide. 2. If you have observed a rougher texture on one side of the paper, try printing on the smoother side. 3. Make sure that the environmental specifications for the device are being met. (See Operating environment on page 22.) 4. Make sure that type and quality of the media that you are using meet HP specifications. (See Media specifications on page 15.) 5. The fuser might be defective. Replace the fuser (see Fuser on page 139). 6. The ECU might be defective. Replace the ECU (see Laser/scanner on page 142). Repeating defects 1.
