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 control panel.

On the PRINT QUALITY submenu, select FUSER MODES, and then select the paper
type you are using. Change the setting to HIGH1 or HIGH2, 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



2. If you have observed a rougher texture on one side of your paper, try printing on the

smoother side.

3. Try using a different type of paper.

4. Make sure that the environmental specifications for the printer are being met. (See

Environmental specifications
