In an example, a method includes receiving, by at least one processor, an instruction to print a user specified printing task to at least one media sheet. Print operation instructions may be determined. Such print operation instructions may comprise instructions to control a print apparatus to print the user specified printing task and instructions to control a print apparatus to carry out at least one cleaning operation, wherein the cleaning operation comprises duplex printing a print media sheet.

An image forming apparatus comprises an image forming section which forms an image on an image receiving medium with a color material; a heating member which heats the image receiving medium; a heater which heats the heating member; a sensor which detects a temperature of the heating member; and a controller which executes a print job for forming an image on the image receiving medium with the image forming section and fixing the image on the image receiving medium with the heating member and a decoloring job for decoloring the image on the image receiving medium with the heating member and interruptedly executes an executable job in a state of stopping output of the heater if the temperature of the heating member is higher than a temperature control range of a job of which priority is highest and there is the executable job at the temperature of the heating member.

An image forming apparatus according to the present invention includes a control unit 111 which performs white paper cleaning by making remaining papers pass through a fixing device in automatic purge of conveying and discharging the remaining papers after an originating paper having caused a jam is removed when the jam has occurred in a paper conveyance path, and display units 115 and 111 which display the number of papers, which is obtained by subtracting the number of the papers having passed through the fixing device by the control unit for the white paper cleaning in the automatic purge from the set number of papers set in advance as the number of papers required to pass through the fixing device in the white paper cleaning, as the number of papers set for white paper cleaning after the automatic purge.

An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

In an example, a method includes receiving, by at least one processor, an instruction to print a user specified printing task to at least one media sheet. Print operation instructions may be determined. Such print operation instructions may comprise instructions to control a print apparatus to print user specified printing print apparatus to print the user specified printing task and instructions to control a print apparatus to carry out at least one cleaning operation, wherein the cleaning operation comprises duplex printing a print media sheet.

An image forming apparatus includes a fixing device and a controller. The fixing device includes a heating unit and a pressurizing unit. The heating unit is configured to come into contact with a recording medium, onto which an image is transferred and which is transported, so as to heat the recording medium while rotating. The pressurizing unit is configured to press the recording medium against the heating unit. The fixing device is configured to fix the image to the recording medium. The controller is configured to control switching between a first mode for fixing the image to the recording medium and a second mode for making a transport speed of a sheet member that passes through the fixing device slower than a peripheral speed of the heating unit.
