Abstract

A sheet processing apparatus capable of creating fold sections suitable for an apparatus that performs saddle-stitch processing on fold sections. A sheet processing apparatus includes a printer engine configured to form an image on a recording sheet. The sheet processing apparatus sets a bookbinding lap which is a distance between a first sheet end and a second sheet end of the recording sheet assumed to have been folded in two. A finisher creates the fold section by forming a folding line on recording sheets according to a reference line which is shifted from the centerline of the recording sheet by the bookbinding lap.

First claim

What is claimed is:

1. A sheet processing apparatus capable of performing folding processing on sheets, comprising:
an image forming unit configured to form an image on a sheet;
a fold unit configured to form a fold line on the sheet having the image formed thereon by the image forming unit and discharge the sheet having been folded in two along the fold line;
a storage device; and
a processor configured to execute computer executable instructions recorded on the storage device, the computer executable instructions including instructions, that when executed by the processor, cause the sheet processing apparatus to:
receive a bookbinding lap and receive a folding position-adjustment amount, the bookbinding lap being received according to a first user setting through a console section and the folding position-adjustment amount being received according to a second user setting through the console section, the first user setting and the second user setting each being independently received; and
control the fold unit to form the fold line at a folding position determined based on the received bookbinding lap and the received folding position-adjustment amount.

2. The sheet processing apparatus according to claim 1 , wherein the processor causes the sheet processing apparatus to determine a position of the image formed on the sheet by the image forming unit based on the received bookbinding lap irrespective of the received folding position-adjustment amount, and control the image forming unit to form the image at the determined position.

3. The sheet processing apparatus according to claim 1 , wherein the processor causes the sheet processing apparatus to receive a print position-adjustment amount corresponding to an adjustment amount of a position of the image formed on the sheet by the image forming unit, and controls the image forming unit to form the image at a position determined based on the received bookbinding lap and the received printing position-adjustment amount.

4. The sheet processing apparatus according to claim 3 , wherein
said fold unit is capable of stacking and folding a plurality of sheets, and
said processor causes the sheet processing apparatus to receive a protruding amount of an inner sheet when the sheets are stacked and folded, and control the image forming unit to form the image at a position determined based on the received bookbinding lap and the received print position-adjustment amount.

5. The sheet processing apparatus according to claim 1 , wherein said image forming unit forms the image at a position shifted from a centerline of the sheet.

6. The sheet processing apparatus according to claim 1 , wherein an adjustment range of the bookbinding lap is greater than an adjustment range of the folding position-adjustment amount.

7. A method of controlling a sheet processing apparatus capable of performing folding processing on sheets, comprising:
forming an image on a sheet;
receiving a bookbinding lap and receiving a folding position-adjustment amount, the bookbinding lap being received according to a first user setting through a console section and the folding position-adjustment amount being received according to a second user setting through the console section, the first user setting and the second user setting each being independently received; and
forming a fold line on the sheet having the image formed thereon and discharging the sheet having been folded in two along the fold line, the fold line being formed at a folding position determined based on the received bookbinding lap and the received folding position-adjustment amount.

8. A non-transitory computer-readable storage device storing a computer-executable program for causing a computer to execute a method of controlling a sheet processing apparatus capable of performing folding processing on sheets,
wherein the method comprises:
forming an image on a sheet;
receiving a bookbinding lap and receiving a folding position-adjustment amount, the bookbinding lap being received according to a first user setting through a console section and the folding position-adjustment amount being received according to a second user setting through the console section, the first user setting and the second user setting each being independently received; and
forming a fold line on the sheet having the image formed thereon and discharging the sheet having been folded in two along the fold line, the fold line being formed at a folding position determined based on the received bookbinding lap and the received folding position-adjustment amount.
