To maintain optimum printing quality, clean your  PriorityFax after

every three or four rolls of recording paper you use.

To clean the interior of the fax machine, follow these steps:

Unplug the machine before cleaning it to avoid electric
shock.

Unplug the machine.

Press down on the recording paper cover  button to open up the fax
machine.

Remove the recording paper roll.

Use a soft cloth or a cotton swab soaked in isopropyl alcohol to
gently clean the surfaces and rollers inside the machine. Be
particularly careful to clean the  clear plastic cover of the scanner

(indicated by the two arrows in the illustration below)  and the
white document pressure bar above it.
