摘要:
An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period.

A sheet stacking apparatus including first and second stacking trays configured to stack sheets, a detection unit configured to detect a sheet stacking amount on the first stacking tray, a setting unit configured to set an upper limit on stacking amount for controlling the sheet stacking amount that is less than a maximum sheet stacking amount on the first stacking tray, and a control unit configured to stop stacking of sheets on the first stacking tray and stack sheets on the second stacking tray in a case where the sheet stacking amount which is detected by the detection unit reaches the upper limit on stacking amount that is set by the setting unit.
摘要:
A sheet processing apparatus which is capable of accurately superimposing or aligning sheets discharged from an image forming apparatus during buffering even when the space intervals between the sheets are reduced. A sheet processing apparatus sequentially receives sheets discharged from an image forming apparatus and carries out post-processing on the sheets. During execution of the post-processing on the sheets, a plurality of sheets are discharged successively from the image forming apparatus and superimposed one upon another around a buffer roller. The conveying speed of the sheets is controlled such that a conveying time period over which a sheet preceding a final one of the sheets to be superimposed one upon another around the buffer roller is conveyed over a predetermined path section is shorter than a conveying time period over which the final one is conveyed over the predetermined path section.

A discharged sheet is conveyed, by a sheet conveying portion movable above sheet stacking portions while supporting a sheet, to selected one among plural sheet stacking portions. When the sheet is conveyed to the selected sheet stacking portion by the sheet conveying portion, a member for preventing a bringing-together provided in the main body of the apparatus prevents a sheet bundle, stacked in a sheet stacking portion at the upstream side of the selected sheet stacking portion, from being brought together by the sheet conveyed above the upstream sheet stacking portion by the sheet conveying portion.

There is provided an image forming apparatus that is capable of preventing input errors and eliminating the necessity of complicated input operations in making settings for a sheet mixing operation in which color image output sheets and black-and-white image output sheets are mixed into one group. A stacker tray stores sheets with color images formed thereon by a color MFP and is equipped with a storage device, into and from which information relating to the sheets can be written and read. A black-and-white MFP operates in response to attachment of the stacker tray to an inserter attached to the black-and-white MFP, to execute an image formation job by providing control such that the sheets with color images formed thereon stored in the stacker tray and sheets with black-and-white images formed thereon by the black-and-white MFP are mixed according to the information stored in the storage device of the stacker tray.
摘要:
An image forming apparatus has a first stacking unit for stacking regular sheets on which images are formed, an image forming unit for forming an image on a regular sheet fed from the first stacking unit, a second stacking unit for stacking the insertion sheets, a delivery unit for discharging the regular sheets from the image forming unit and the insertion sheets from the second stacking unit into a single sheet discharge section, and a paper thickness detection unit provided on a common carrier path through which the regular sheets carried from the image forming unit and the insertion sheets delivered from the second stacking unit are transported for detecting the thickness of the regular sheets and the insertion sheets.

There are provided an image forming apparatus and a method of controlling the same are provided, which are capable of conveying an insert sheet of a proper page in carrying out a recovery process and simplifying the recovery process, and a storage medium storing a program for executing the method. When a printing start instruction is input and an insert mode has been set, an insert sheet is fed. It is determined whether the insert sheet is for a top page of a copy (bundle) or not. When the insert sheet for the top page is detected, a proper printing operation in the insert mode is started. If the insert sheet is not determined to be for the top page, it is judged that the insert sheet has not been correctly set on the inserter tray, and then the insert sheet is discharged to a non-sort tray. Then, insert sheets are discharged to the non-sort tray until the insert sheet for the top page is detected.
摘要:
A sheet processing apparatus comprising a sheet stacking member for stacking a sheet to be discharged, and an offset mounting member for offsetting a plurality of sheet bundles on sides in a sheet bundle takeout direction and in a direction opposite thereto, and mounting the offset bundles onto the sheet stacking member. The offset mounting member mounts the first sheet bundle on the side in the sheet bundle takeout direction. When there is a sheet bundle on the sheet stacking member, the first sheet bundle is mounted by offsetting the first sheet bundle in a direction opposite to that of the last sheet bundle mounted.
摘要:
A punching apparatus having a punching member which effects punching on a sheet, and a driving mechanism which moves the punching member in a sheet width direction intersecting with a sheet conveying direction. On the basis of the difference between the position of a current sheet and the position of a next sheet succeeding thereto detected by a detecting sensor which detects the position of each conveyed sheet in the sheet width direction, at a position upstream of the punching member, the punching member is moved by the driving mechanism along the sheet width direction from a punching position for the current sheet to a punching position for the next sheet.
