no. 1 Embodiment approach

[0113] (Paper Feed Control During Duplex Printing)

[0114] Here, paper conveyance control during double-sided printing according to the first embodiment will be described.

[0115] Figure 7 (a) is a flow chart of paper conveyance control during duplex printing, Figure 7 (b) is a flowchart showing details of conveyance control at the time of return and return. in addition, Figure 8 It is an explanatory diagram schematically showing the state of the paper P under conveyance control during double-sided printing, Figure 8 (a) show Figure 7 The state of the paper P in step S1 of (a), Figure 8 (b) show Figure 7 The state of the paper P in step S2 of (a), Figure 8 (c) show Figure 7 The state of the paper P in step S3 of (a).

[0116] First, refer to Figure 7 (a), Figure 8 (a) to (c) briefly describe paper conveyance control during double-sided printing. When the print data is print data for double-sided printing, the control unit of the printer 1 performs a pr...

no. 2 Embodiment approach

[0135] (Paper Feed Control During Duplex Printing)

[0136] Here, paper conveyance control during double-sided printing according to the second embodiment will be described. The paper conveyance control during double-sided printing according to the second embodiment is paper conveyance control that recognizes the trailing end position of the conveyed paper P and controls conveyance of the paper.

[0137] First, if Figure 7 (a), Figure 8 As shown in (a) to (c), when the print data is for double-sided printing, the control unit of the printer 1 performs printing processing on the front surface of the paper P in step S1 (first step). That is, in step S1, the paper P is sent from the paper supply path 12 to the main body side conveyance path 13 via the common path 30 by the paper feed roller 15, the retard roller 16, and the conveyance roller 17 (see Figure 8 (a)). Then, the pair of paper feed rollers 21 etc. are driven to convey the paper P in the first direction FF toward...

Abstract

The control unit of a printer feeds paper P from a paper supply path 12 to a main conveyance path, drives a paper feed roller pair, conveys the paper in a first direction through the main conveyance path, and prints on the first side of the paper P. After printing on the first side ends, the conveyance direction changes from the first direction to the opposite second direction, and the medium is back-fed to a looped inverting conveyance path at a faster conveyance speed than the conveyance speed when printing. First and second conveyance rollers are then driven to convey the print medium at high speed through the inverting conveyance path, thereby inverting the front and back and returning the medium to the main conveyance path for printing the second side.

Description

technical field [0001] The present invention relates to a printer provided with a reversing conveyance path for reversing a sheet-like medium such as recording paper to be fed out from the front and back, and to a control method thereof. [0002] This application claims priority to Japanese Patent No. 2013-140425 filed on July 4, 2013, and Japanese Patent No. 2013-140428 filed on July 4, 2013, and uses the contents thereof here. Background technique [0003] As a printer provided with such a conveyance path for inversion, a printer provided with a double-sided automatic printing function is known. In a printer equipped with a double-sided automatic printing function, after printing is performed on the surface of the recording paper, it is conveyed through a conveyance path for reversing, and the front and back are reversed, and printing is performed on the back. Patent Document 1 discloses a printer including a conveyance path for inversion. [0004] After printing on the ...
