• The Fusing Roller Sub Thermistor does not
detect the required temperature within 30 sec.
after a warm-up cycle has begun; therefore, the
copier does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.

Open the top cover. Remove the drum (part with long green handle). Below the drum you will see a strip of glass about 4-5 inches long. Take a cloth and wipe across the glass.

This will normally clear up any white lines in your print.
