摘要:
A sheet conveying apparatus has a first conveying unit for conveying a sheet, a second conveying unit for conveying a sheet in merging with the first conveying unit and a sheet merging overlapping device. At a junction between the first and second conveying unit, the sheet merging overlapping device overlaps the sheet conveyed by first conveying unit with the sheet conveyed by the second conveying unit in a sheet conveyance direction.

The present invention aims at restoring backup data in a predetermined order and avoiding damage from being given to the system even when the backup data are destroyed. Flags Ferr and Feeprom and a variable i stored in a DRAM are initialized (S1 to S3). When the variable i is smaller than the number n of EEPROMs (hereinafter referred to as “PROM(s)”), the ID code of a PROM in question is read and loaded into the DRAM (S4 to S6). When the variable i equals the number n, the variable i is cleared (S7). Then, a variable j is initialized (S9), and it is determined whether or not each PROM ID stored in the DRAM matches with a mask ROM ID until the variable j becomes greater than the number n of PROMs (S11). If the answer is “No”, the variable j is incremented (S13), while if “Yes,” a number corresponding to the variable j then assumed is loaded into the DRAM as the flag Feeprom (S14). Data in the PROM in question is transferred to an area of the DRAM in which is stored the PROM ID matching with the mask ROM ID.

An image forming apparatus reverses a sheet, on one side of which an image has been formed in an image forming section, transports the sheet back to the image forming section, and forms an image on the other side of the sheet, the apparatus has an inlet feed path for transporting a sheet, on one side of which an image has been formed; a switchback path for withdrawing the sheet transported from the inlet feed path; a plurality of reverse feed paths branching from the switchback path at plural positions, each of the reverse feed paths transporting a sheet while reversing the sheet; and a re-feed path for transporting the reversed sheet from any of the reverse feed paths back to the image forming section.

A sheet conveying apparatus permits keeping predetermined sheet intervals, even when sheet conveyance is temporarily discontinued and then resumed, after resumption of conveyance. The sheet conveying apparatus has a first roller which feeds sheets at predetermined sheet intervals, and a second roller which conveys a plurality of sheet fed from the first roller. After temporarily discontinuing conveyance of the plurality of sheets, conveyance of the plurality of sheets is resumed by use of the first roller and the second roller. The variation in the sheet interval caused when temporarily discontinuing sheet conveyance is corrected upon resumption of sheet conveyance.
摘要:
An image forming apparatus which is capable of bringing processing devices, such as sheet feed devices and post-processing devices connected respectively to the image forming apparatus, into operable states in timing optimal for carrying out an image forming job, thereby improving productivity and operation rate of the image forming apparatus as well as saving energy. A print job is analyzed to determine at least one sheet feed device and at least one post-processing device to be used in executing the print job, and states of the determined devices are checked to determine at least one of the sheet feed device and the post-processing device to be caused to start a preparatory operation in advance before the print job is executed. Power supply to the at least one of the sheet feed device and the post-processing device is turned on in timing such that the preparatory operation is completed in time for the start of execution of the print job.
摘要:
There are provided an image forming apparatus which is capable of efficiently performing necessary actions to thereby reduce downtime. At least one job can be registered. Image formation is performed according to the at least one registered job. Action objects are detected on which actions necessary for the image forming apparatus should be taken.
摘要:
An image forming system which is capable of performing double-sided clear coating. The image forming system comprises an image forming apparatus configured to form an image on a sheet, and a clear coating apparatus configured to perform clear coating on the sheet using clear toner. The image forming apparatus is provided with a double-sided image forming function for forming images on the respective opposite sides of a sheet, and the clear coating apparatus is provided with a double-sided clear coating function for performing clear coating on the opposite sides of a sheet.
摘要:
An image forming apparatus which conveys waste toner includes a buffer portion 101 capable of temporarily containing the waste toner and a waste toner container 102 capable of containing the waste toner and a waste toner container 102 capable of containing the waste toner. The waste toner is dominantly contained in the waste toner container 102 compared with the buffer portion 101. When the waste toner container 102 is filled with the waste toner, the waste toner can be contained in the buffer portion 101. An engine controller 120 detects whether the buffer portion 101 is filled with the waste toner 112 or not through a buffer portion waste toner full state detection sensor 105. When the buffer portion 101 is filled with the waste toner 112, the engine controller controls so that a conveyance operation by a first waste toner pipe 103 and an image forming operation are stopped.
