Patent ID: 7933542

Claim:
A system for cleaning a fuser in an image-forming device, comprising: a detecting unit for detecting an image-transfer sheet at a predetermined location in a print path after a fusing operation performed at a first predetermined temperature to generate a print complete signal; a fuser roller located in a fuser; a fuser separation pawl in contact with said fuser roller; a cleaning roller located near said fuser separation pawl for collecting residual toner via a pressure roller; and a controller operationally connected to the fuser for intermittently activating for a predetermined number of times said fuser roller in response to the print complete signal and upon detecting one event from a group of events consisting of document setting on an automatic document feeder, opening/closing the automatic document feeder and touching a control panel by a user to heat said fuser roller from a non-operating temperature range to a predetermined operating temperature while the fuser roller is being rotated, the group of the events failing to issue a print command, said fuser separation pawl receiving the heat from said fuser roller, said controller deactivating said fuser roller upon reaching the predetermined operating temperature, wherein after a first predetermined amount of time following the deactivation, said fuser roller and said fuser separation pawl cools off to the non-operating temperature range and the residual toner on said fuser separation pawl consequently falls off due to gravity, said controller rotating said cleaning roller to collect the residual toner via said pressure roller for a second predetermined amount of time.
