Abstract: A computer readable storage medium stores a feeding and conveyance control program. The feeding and conveyance control program causes a computer to perform executing sequence control of a feeding sequence module with respect to a feeding mechanism that feeds the recording medium. The sequence control includes two kinds of sequence control executed in accordance with an identifier indicating whether the vertical conveyance mechanism exists. Sequence control of a vertical conveyance sequence module is executed with respect to a vertical conveyance mechanism that relays conveyance of the recording medium. Sequence control of a resist conveyance sequence module is executed with respect to a resist conveyance mechanism that conveys the recording medium to the transfer position at a predetermined timing. Overall management of the above-described modules is executed.

Abstract: 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.

Abstract: In an MFP, when a count of printed sheets of paper exceeds a predetermined count, a controller reads, from internal counters, a frequency of a stabilization process executed in return, a frequency of a stabilization process executed automatically in printing, a frequency of a stabilization process executed manually based on a user's instruction, and a frequency of return, respectively. When the frequency of the stabilization process executed automatically is small while the frequency of the stabilization process executed manually is large, the controller raises a frequency level of execution of the stabilization process. When the frequency of the stabilization process executed manually is small, the controller lowers the frequency level of execution of the stabilization process.

Abstract: An image forming apparatus that warns that a JOB fails to be pulled out is provided. Warning processes executed by a CPU of a printer that is one example of the image forming apparatus includes the steps of determining whether a JOB list is updated, setting a job counter JB_S_CTA for checking JOB at an initial value “1” and setting an upper limit counter JB_S_CTB at an upper limit value when the JOB list is updated, executing a failure-to-pull-out warning process if JOBs counted by JB_S_CTA belong to the same client, and incrementing the JB_S_CTA by “1”.

Abstract: 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.

Abstract: The count data recording device includes: a storage unit that includes N memory areas storing the count data pieces; a data writing unit that writes a count data piece to the storage unit; a data reading unit that reads the count data piece from the storage unit; and a data restoring unit that detects a corruption in the count data pieces stored in the storage unit 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, and wherein the data restoring unit: derives a sorted count data sequence so that values of the count data pieces vary monotonously; derives a count data difference value sequence; and detects and restores the corruption in the count data pieces based on the sorted count data sequence and the count data difference value sequence.

Abstract: A process cartridge having a nonvolatile memory for storing prescribed information corresponding to addresses is detachably attached to a main body of an image forming device. The nonvolatile memory includes a first address at which data including a shipment destination used by a control system of the main body of the image forming device is stored, a second address where data including process control information to further control the control system of the main body is stored, a first unused address at which data including a destination code is stored and which is used by the control system of the main body of the image forming device is not defined, and a second unused address at which no data is stored and of which use by the control system of the main body of the image forming device is not defined.

Abstract: 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.

Abstract: 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.

Abstract: A process cartridge having a nonvolatile memory for storing prescribed information corresponding to addresses is detachably attached to a main body of an image forming device. The nonvolatile memory stores first destination information of “shipment destination” data to be used to control the printing operation by a control system of the main body of the image forming device and second destination information of “lot No.” data not to be used to control the printing operation by the control system. The nonvolatile memory allows the image forming device to perform an appropriate printing operation without changing a program of the main body of the image forming device even when a new destination is arisen for a reason of production management, marketing etc. after beginning to put the image forming device on the market.

Abstract: A license management apparatus is taught which includes a storing portion to store licenses for each of a plurality of operation functions of one of a plurality of operating function executing units, a discriminator to discriminate whether the number of licenses currently permitted for the use of one of the operation functions has reached a predetermined number based on contents of the storing portion upon request for a use of one of the operation functions, and a determination unit to determine whether the request for the use of one of the operation functions is to be permitted based on a discrimination result of the discriminator.

Abstract: An image processing apparatus avoids abnormal control on loads including an optional device and enables only program transfer when transfer of a control program from an external device is not normally proceeding. Through a communication interface, the control program is transferred from the external device to a flash memory via an external controller, while a transfer state thereof is stored in EEPROM. In response to the state of the EEPROM, CPU controls power supply to the external controller and the optional device to avoid abnormal operation of the optional device during transfer of control programs.
