Title: Image recorder
Inventor: ENDO YOSHINORI
IPC: G03G15/20
Filed: 1994-05-16
Abstract: PURPOSE:To prevent the wrong detection of an error from occurring by stopping an error detecting operation or setting a detecting temperature lower, for a prescribed period just after an image forming action was started and a period that the image forming action is not taken. CONSTITUTION:When printing is started from a standby state, a halogen heater is energized to change the temperature of a fixing unit 5 from a standby temperature of 130 deg.C to a printing temperature of 150 deg.C and simultaneously a heating roller 5 is rotated by the drive of a main motor 17. In the beginning of the rotation, the heat of the heating roller 5a is transmitted to a pressure roller 5b in accordance with the rotation and there is a possibility that the temp. of the fixing unit 5 is transiently lowered to <=120 deg.C. However, at this time, as abnormality detecting processing, the temp. for checking the error is made to be 40 deg.C for five seconds after the start of the printing and 120 deg.C after the lapse of five seconds, so that even if the temp. of the fixing unit 5 transiently drops, the error is never detected by the drop. Moreover, even when the operation for checking the error is stopped, the similar work can be obtained.
