Problems solved by technology

In addition, for large-sized paper, it is necessary to ensure a sufficient distance between the first fixing device, the second fixing device, and the cutting unit, and thus there is a disadvantage that the image forming apparatus is considerably enlarged.

[0131] Next, referring to Figure 9A- Figure 9C , Figure 10 A second embodiment will be described. Figure 9A~ Figure 9C It is a diagram for explaining the conveyance process in the fixing unit 6 when a paper jam occurs in the second embodiment. Figure 10 It is a flowchart showing the conveyance process in the fixing unit 6 when a paper jam occurs in the second embodiment.

[0132] The second embodiment differs from the first embodiment in the transport method of the fixing-stopped paper P0 when a paper jam occurs. However, the configuration of the printer 100 of the second embodiment, the identification of the front end and the rear end of the paper P, and detection of paper jams, etc., are all the same as those of the first embodiment except for the method of transporting the fixing-stopped paper P0 when a paper jam occurs. Likewise, the description of the first embodiment can be cited. Therefore, with regard to the second embodiment, only the characteristics differen...

Abstract

An image forming apparatus according to one aspect of the present disclosure includes print engine portion, paper sheet detectors, and control portion. Control portion stop paper sheet conveyance, when detecting occurrence of jam. Control portion determines fixing nip position which is position of the fixing nip portion on fixing stop paper sheet, on basis of outputs of paper sheet detectors. When fixing nip position is located at leading end side half of fixing stop paper sheet in paper sheet conveying direction, control portion rotates fixing motor in reverse direction to convey fixing stop paper sheet to upstream side in paper sheet conveying direction. When fixing nip position is located at rear end side half of fixing stop paper sheet in paper sheet conveying direction, control portion rotates fixing motor in a forward direction to convey fixing stop paper sheet toward a downstream side in paper sheet conveying direction.

Description

technical field [0001] The present invention relates to an image forming apparatus for fixing a toner image on paper by heating and pressing. Background technique [0002] Paper jams sometimes occur in image forming apparatuses such as printers. After a paper jam is detected, in order to prevent the paper jam from aggravating, it is necessary to perform printing operations such as stopping paper feeding. However, if the paper carrying the toner image stops on the fixing unit when the paper transportation is stopped, the quality of the image formed thereafter will be degraded, or the melted toner will adhere to the members of the fixing unit. Therefore, the image forming apparatus is provided with means for conveying the paper until it passes through the fixing unit when the paper jam occurs and stops the paper feeding so that the paper does not stop on the fixing unit. [0003] For example, there is a known image forming apparatus, comprising: a first fixing device, which ...
