[6] Troubleshooting

1. Using the RESET key

If the fax machine stops responding when you press any of the oper-

ation panel keys, you must reset it. This can be done as follows:

Grasp the print compartment cover at both sides as shown, and

pull up to open the cover.

• Caution!

The fusing unit inside the print compartment becomes very hot

during operation. Do not touch the inside of the compartment o

the paper guide on the underside of the print compartment cover.

Use a ballpoint pen to press the RESET button.

• Note: Pressing the RESET button clears any documents that are

stored in memory.

Close the print compartment cover, pressing down firmly on each

side to make sure it is completely closed.
