I don't have power. Is there an on/off switch?

There is no power switch on this machine & the supply cable is hard wired into the machine.
Have you tried a new fuse in the plug?
If so, & it still doesn't work then you may have a power supply problem.
Hope this helps.

1Press Menu/Set, 0, 2.

3 Enter two digits for the month. Press Menu/Set.

(For example, enter 09 for September, or 10 for October.)

4 Enter two digits for the day. Press Menu/Set.

(For example, enter 06 for 6th.)

5 Enter the time in 24-Hour format. Press Menu/Set.

The LCD now shows the date and time whenever the machine is idle in Fax mode.

When the machine is in Sleep mode, the LCD shows Sleep. (See Sleep Time on page 2-8.)

Hopefully that worked correctly and solved your problem!

WHAT: Either the main thermistor doesn't attain 30?C 1 second after the power switch is activated or it doesn't attain 70?C 2 seconds thereafter.

WHY: It has a faulty fixing film unit, lack of connectivity with the main thermistor, lack of connectivity with the fixing heater, a faulty main power supply PCB, or the DC controller PCB is faulty.

NOTE: You can reset the error by performing the following in service mode: COPIER>FUNCTION>CLEAR>ERR.

CONNECTOR FIX: Make sure that the connector of the fixing assembly is seated.
A. main power supply PCB (J8) relay connector heater
B. DC controller PCB (J320) relay connector thermistor

FIXING FILM UNIT (THERMISTOR) FIX: With a multimeter, check the interval between pin 1 & pin 2 & between pin 3 & pin 4 of the connector (4-pin) of the thermistor for electrical continuity. A result of ?? means that the circuit is open (lack of connectivity). Resolve this by replacing the fixing film unit.

MAIN POWER SUPPLY PCB, DC CONTROLLER PCB FIX: Press the Start key. If the drive voltage of the heater is supplied by the connector J8 of the main power supply PCB, then the main power supply PCB should be replaced. If not, then the thermistor control mechanism is faulty & the DC controller PCB should be replaced. Use the following to ascertain this:
Main heater: between J8-1 (FSR1) & J8-5 (FSR COM)
Sub heater: between J8-3 (FSR2) & J8-5 (FSR COM)

Mine stopped working and the overheat light comes on. it will run in reverse OK, but as soon as you go to forward and put a peice of paper in it, red overheat light comes on right away. Took it apart, inside was totally jammed with shredded paper and dust. Packed tight around the motor, gears, everything. It;s a miracle it didn't catch fire! Poor design. Motor commutator was badly glazed, took apart an cleaned it. Still sparks like mad. I think it's toast! Didn't really last that long (less than 2 years) and it wasn't cheap. It going in thr trash I think!

It seems that your fax machine has been damaged by a power "spike" You may or may not be able to get it to work again. You can try to re sequence the machine, by switching off, then removing both the power cord and the telephone cord from the wall. Wait 30 secs or so, then plug in the power cord and switch on. After the machine shows the "ready" mode in the display, then plug in the telephone cord. If this does not work, your machine is toast. Make sure in future to use a line conditioner for both the power and the telephone lines.
