Prevent an image failure caused by a claw mark of the pressure roller.
MEMO:
Since the lower separation claw comes into contact with the pressure roller, a claw
mark remains on the pressure roller. A claw mark is printed on the 1st side when fixing
is performed to the 2nd side of double-sided printing of thick paper. (Since the control
temperature for thick paper is high (150 degree C), toner on the 1st side melts.)
Timing
• Before execution of double-sided printing of thick paper
• When the paper count value of 5000 prints is passed in the condition where the lower
separation claw is engaged.
