Check the operation of the paper full lever and
actuator shaft. Replace as necessary.
Check the sensor for operation. Check for
approximately +5 V from CN109 pin 2 to GND
when the sensor is activated. Replace if necessary.
Be sure the switch is on and the power cord is
firmly plugged into the printer. Be sure the correct
voltage is present at the outlet.
Check the power cord for continuity.
The power supply fuses may be blown. Unplug the
machine and check fuse F1 on the power supply for
continuity. If the fuse is good, check the power
switch connector for continuity.
The power supply may be defective.
Check the dc power of the power supply. Check
pins 7 and pin 5 on connector CN604. Pin 7
(yellow) should read +4.8 V to +5.3 V. Pin 5 (red)
should read +22 V to 26 V. Replace if necessary
(11G0305 115 V, 11G0541 230 V).
