ABSTRACT:
Fixing of images by fuser roller (3) in printer (1) is delayed by control of paper feed clutch (7) when abnormally low power is determined during an earlier cold start or start from standby. Sensed temperature values from thermistor (9) are compared with predetermined value in comparator (15) under control of microprocessor (14). When the time period for heating is longer than a predetermined time, subsequent activation of the clutch is briefly delayed.
