An image forming apparatus, having: a supply unit that forwards a sheet material; a rotor that feeds the sheet material; a memory unit that has stored therein a masking sound for noise; a derivation unit that derives a current position of the sheet material being fed; a determination unit that determines, on the basis of the current position derived by the derivation unit, whether or not the sheet material being fed has reached a second specified location at a predetermined distance upstream from the first specified location; a decision unit that decides output timing and/or output duration for the masking sound in the memory unit upon an affirmative determination by the determination unit; and a sound output unit that outputs the masking sound in the memory unit in accordance with the output timing and/or the output duration.

Image forming apparatus

An image forming apparatus includes a main body storage part, a determination part, and an initial adjustment part. The first image forming unit includes a first storage part storing first information indicative of whether or not an initial adjustment of the first image forming unit has been completed. The determination part determines whether or not the first information stored in the first storage part and the second information stored in the main body storage part satisfy respective prescribed conditions. The initial adjustment part causes the first and second image forming units to perform the initial adjustment when the first information indicates that the initial adjustment of the first image forming unit has not been completed and the second information indicates that the second image forming unit corresponds to an unused state.

The count data recording device includes: a storage unit including N memory areas; and a data restoring unit that detects a corruption in the count data pieces and restores the corruption, wherein the data writing unit records the count data piece using the memory area included in the range of the minor loop according to the predetermined order and shifts the range of the minor loop backward after recording the count data piece using a last memory area within the minor loop.

Count data recording device, and method and program for recording count data

Time required for setting a print mode in a print standby state is shortened, in performing recovering operation. In an attachment state of consumable units on an image forming apparatus, information of the consumable unit memorized in nonvolatile memories of consumable units is memorized in a second nonvolatile memory, and after the print mode is set in an unprintable state, recovering operation having possibility of replacing the consumable units is performed. Thereafter, whether the same consumable units as those before the unprintable state are attached to the image forming apparatus is determined. At this time, a signal based on the information of the consumable units memorized in the nonvolatile memory is transmitted to a bus connected to a plurality of nonvolatile memories, and when there is a reply of a part of the information in the nonvolatile memories to this transmission, it is determined that the same consumable units as those before the unprintable state are attached to the image forming apparatus.

When electronic mail with firmware attached is received at a data communication apparatus, determination is made whether it corresponds to firmware data of a write process allowable state. In the case of write process allowable data, the message is downloaded from a mail server to a printer controller. Then, derived firmware is transmitted to an image formation apparatus. A firmware rewrite permission is obtained. When the firmware attached to the message does not attain a write process allowable state, waiting is conducted for reception of write process allowable firmware with the data left in the mail server. As a result, a data communication apparatus is provided that can rewrite firmware appropriately independent of a transmitted and received order of divided firmware.

Data communication apparatus capable of rewriting firmware

When an image forming apparatus is disabled due to a cause rather than the detection of the toner empty condition, it is determined whether a recovery operation is a first recovery operation or a second recovery operation. The first recovery operation is associated with a mounting/dismounting of the toner cartridge performed from when the image forming apparatus is disabled until when the recovery operation begins. The second recovery operation is not associated with the mounting/dismounting. A toner supply control controls the toner supply operation when the recovery operation is performed on condition that the empty memory memorizes that the toner empty detector detects the empty condition. When the recovery operation is the first recovery operation, the toner supply control allows the toner to be supplied into the developer housing. While, when the recovery operation is the second recovery operation, the toner supply control prohibits the toner from being supplied into developer housing.

An image forming apparatus in which the consumption article can be attached to and detached from a main body has a controller, which reads first new/old information that is stored in a repetitively rewritable area of a memory provided on the consumption article and represents whether or not the consumption article is unused after manufacturing or after recycling and second new/old information that is stored in a once rewritable area of the memory and represents the number of times of recycling of the consumption article and controls the operation of the image forming apparatus on the basis of the first new/old information and the second new/old information.

An image processing apparatus checks a next job to be executed, and if the job is a firmware rewriting job, accesses a mail server, downloads e-mail, and obtains a job type of a job attached to the e-mail. If the job is a print job, the image processing apparatus extracts image information pertaining to the job from the e-mail, stores the image information, registers the job in a job management table, and ends processing. If there are no print jobs, the image processing apparatus executes the firmware rewriting job, deletes the job from the job management table, and ends the processing.

An image forming apparatus, in which a consumption article can be attached to and detached from a main body, has a device that makes an access to a memory provided on the consumption article, a device that determines whether or not an access failure has occurred during the access to the memory, and a device that switches over between warning levels according to the address of the memory where the access failure has occurred or an attribute concerning write and read where the access failure has occurred.

An image forming system having an image forming apparatus and a post-processing apparatus having a sorting function, a stapling function, etc. The post-processing apparatus is movable between a first position to receive long papers and a second position to receive non-long papers. When the post-processing apparatus is set in the second position, a paper inlet port of the post-processing apparatus faces a paper ejection port of the image forming apparatus.

A data broadcasting receiving terminal receives a data broadcasting signal from a broadcasting station to detect print-out data and a control signal associated with print-out from the data broadcasting signal. The data broadcasting receiving terminal, at a time point of the start of broadcasting, notifies an image forming apparatus of the detected print-out data and printing prohibition data included in the control signal associated with print-out. The data broadcasting receiving terminal acquires a preparation time required for print-out from the image forming apparatus and a time of restoration from a power saving mode and issues a command of printing start, in consideration of the time requirements, to the image forming apparatus so that print-out data is printed out at predetermined timing.

When electronic mail indicating termination of firmware rewriting has arrived from an image formation apparatus that has received divided firmware, the transmitter side of the firmware determines whether rewriting has ended properly or not from the mail. When rewriting has ended properly, electronic mail with the next divided firmware attached is transmitted based on the division number, divisor value, machine type and module indicated in a Subject field. When rewriting has not ended properly, the same firmware indicated in the Subject field is transmitted again. Accordingly, divided firmware can be transmitted appropriately. Thus, firmware of a large size can be transmitted appropriately even in the case where the size set at the mail server is restricted.
