Problems solved by technology

Therefore, there is a problem that in an image forming apparatus equipped with a plurality of sheet feeding cassettes, it takes a lot of labor and time
In addition, the paper on which the printing position adjustment pattern is printed is usually discarded after the measurement of the printing position is completed, so there is a problem of waste of paper.

Embodiment approach

[0044] Next, while referring to Figure 4 , Figure 5 The configuration and execution procedure related to the embodiment of the present invention will be described. Figure 4 It is a functional block diagram of the digital compound machine of the present invention. in addition, Figure 5 It is a flowchart showing the execution procedure of the present invention.

[0045] First, when the user activates the multifunction peripheral 100 , the display accepting unit 401 of the multifunction peripheral 100 displays a predetermined operation screen on the touch panel 201 to accept input of setting conditions and the like from the user.

[0046] Here, when the user wants to adjust the printing position of the digital multifunction peripheral 100, the user moves to the system screen by key operation, and presses a printing position adjustment key (not shown). Then, the display receiving unit 401 accepts the pressing of the print position adjustment key, and shifts from the normal...

Abstract

The invention provides an IMAGE FORMING APPARATUS AND a PRINT POSITION ADJUSTMENT METHOD, wherein the IMAGE FORMING APPARATUS includes a plurlaity of paper supply boxes, a print pattern forming unit, a displacement amount calculation unit and a compensation unit, wherein the position print pattern forming unit forms plural comparative print patterns on a sheet by reference print patterns corresponding to every sheet feed cassette associated with different reference positions for every sheet feed cassette. The displacement amount calculation unit reads the comparative print patterns on the sheet, and calculates displacement amounts between the reference positions and comparative positions of the read comparative print patterns corresponding to the reference positions. The correction unit corrects the print position of the sheet conveyed from the sheet feed cassette based on the displacement amount for every sheet feed cassette.

Description

technical field [0001] The present invention relates to an image forming apparatus and a printing position adjustment method, and more specifically, to an image forming apparatus and a printing position adjustment method capable of reducing the number of adjustment steps and reducing wasted paper. Background technique [0002] Conventionally, in image forming apparatuses such as digital multi-function peripherals and copiers, there are various techniques for adjusting the position of paper to be conveyed and the position of an image to be formed. [0003] For example, there is known an image forming apparatus that includes an edge detection unit that detects the top and side edges of recording paper in a printing unit. The apparatus moves the printing unit in the main scanning direction and the recording paper in the sub-scanning direction at predetermined timings based on a detection signal from the edge detection unit to form an image on the recording paper. In addition, ...
