Image forming apparatus

Abstract

The invention provides an image forming apparatus which may simply identity a position in which the image defect such as image cracks occurs. When conveyance checking mode is selected, a menu screen of a display panel is switched to an automatic setting screen (400). A reduced screen (440) of an image forming apparatus (100) is displayed on the automatic setting screen (400). ADU rollers (44), guide plates (45) and sheet ejection rollers (52) which are used when the sheet of paper P is conveyed are are selectable. When the components are selected, they are highlighted in color and names of the selected components are also represented. When the selection of the components is finished, a test printing operation is carried out; and the sheets of paper stop at their stop positions corresponding to the selected components. A user removes the sheets of paper from their stop positions and checks an image pattern formed on each of the removed sheets of paper.

Description

technical field [0001] The present invention relates to an image forming apparatus that can easily confirm where an image defect on a sheet occurs by stopping the sheet at a designated position. Background technique [0002] Conventionally, various image forming apparatuses have been proposed that can identify a location where a problem occurs within the apparatus. For example, Patent Document 1 discloses a printing device that, when a paper jam occurs in the printing device, specifies the position where the paper jam occurred, and sends a method of removing the jammed paper to a higher-level device. In addition, Patent Document 2 discloses an image forming apparatus that identifies a location where a conveyance abnormality such as a paper jam has occurred, and stops power supply only to drive members related to the location. In addition, Patent Document 3 discloses an image forming apparatus that, when a paper jam is detected by a paper jam sensor, moves a movable unit to ...

AI Technical Summary

Problems solved by technology

However, in the image forming apparatus disclosed in the above-mentioned Patent Document 1, although it is disclosed that the occurrence position of the paper jam is identified, etc., it is not disclosed that the inspection of the transport guide plate in the apparatus is not disclosed.

[0007] In addition, in a general image forming apparatus, as a method for inspecting a defect of components constituting the image forming apparatus, there are a method of measuring the potential of the photoreceptor, and a method of inspecting the durability of the roller according to the timing of conveyance. There is no method of inspecting the transport rollers and guide plates in the image forming apparatus

[0008] Therefore, in the conventional image forming apparatus, when image defects such as image damage, roller marks, and scratches occur, it is difficult to identify the occurrence position of the image defect.

As a result, when an image defect problem occurs, the adjustment time for the user or maintenance personnel to adjust the device is prolonged, and the failure time of the image forming apparatus also becomes prolonged. As a result, the work of the user or maintenance personnel is Increased burden
