PURPOSE:To enable prevention of sheet discoloration or crease generation even when printing is suspended halfway with sheets still set in place or held up by detecting the holding-up of sheets on a fixing heater for more than a set time and ejecting them when such a condition occurs. CONSTITUTION:A timer 28 counts time spent from a moment when the tip of recording sheet 5 arrives at a fixing heater 6 to every moment When the recording sheet 5 continues to be held up on the fixing heater 6, and transmits the time to CPU 21 sequentially. When next character data no longer exists halfway through printing process or the transmission of character data is stopped from a host 30 to suspend a printing action temporarily, or the printing action comes to a standstill for any other reasons, the hold-up time of the sheet 5 on the fixing heater 6 is detected by the timer 28, if the sheet 5 is held up on the fixing heater 6. Then a sheet feed roller 1 is caused to rotate by CPU 21 via an LFM(sheet feed motor) driver 32 and an LF(line feed) motor 33 when the holdup time reaches a set value. |
