There is provided an image forming apparatus configured to process print data of a plurality of pages includes a plurality of interpreters configured to generate intermediate data of the plurality of pages by interpreting the print data, a control unit configured to specify different pages for different interpreters, and, for each specified page, cause a corresponding interpreter to generate the intermediate data of the specified page or specified pages, and a generation unit configured to generate a raster image of the page based on the generated intermediate data, wherein, based on interpretation of the print data of an invalid page, any one interpreter of the plurality of interpreters generates the intermediate data of a page subsequent to the invalid page without requiring the page to be specified by the control unit.

An information processing device includes: an acquisition unit configured to acquire a determination result of a state of a user, who has given a transmission job execution instruction, determined based on biological information of the user; and a job control unit configured to control an execution of the transmission job according to the user state determination result, wherein when it is determined that the user is in an off-normal state, the job control unit executes a confirmation request process to request the user to make a confirmation related to the transmission job.

In accordance with an embodiment, an image forming apparatus comprises a main scanning counter, a controller, and an interval determination section. The main scanning counter counts a first count value indicating the number of times a synchronization signal for synchronization between the apparatuses is input to itself, and registers the first count value to an initial value if a main scanning reference signal indicating a progress state of exposure in a main scanning direction is input to itself. The controller generates PreHSYNC generated at the same interval as the main scanning reference signal. The interval determination section determines that an abnormality occurs in the main scanning reference signal if the first count value satisfies a predetermined condition at a timing at which the PreHSYNC is input to itself.

An information processing apparatus includes a first acquiring unit that acquires a processing attribute of a printing process corresponding to a printing instruction for executing the printing process using print data, a second acquiring unit that acquires an apparatus attribute of an image forming apparatus that executes the printing process, a third acquiring unit that acquires a data attribute of the print data, a print data interpretation unit that performs an interpreting process for the print data based on the processing attribute, a request unit that requests the print data interpretation unit to perform the interpreting process according to the printing instruction when it is not possible to determine from at least one of the processing attribute, the apparatus attribute and the data attribute whether or not an error occurs in the printing process, and a controller that displays information indicating that the error occurs in the printing process.

An image forming apparatus for forming an image on a recoding medium based on document data includes a memory that stores a program and a processor that executes the program stored in the memory to perform a process. The process includes determining an occurrence of an error made by the image forming apparatus or a user of the image forming apparatus, determining whether the document data is confidential, deciding on one or more actions to be performed based on the error and whether the document data is confidential, and implementing the decided one or more actions.

An information processing apparatus includes a first acquiring unit that acquires a processing attribute of a printing process corresponding to a printing instruction for executing the printing process using print data, a second acquiring unit that acquires an apparatus attribute of an image forming apparatus that executes the printing process, a third acquiring unit that acquires a data attribute of the print data, a print data interpretation unit that performs an interpreting process for the print data based on the processing attribute, a request unit that requests the print data interpretation unit to perform the interpreting process according to the printing instruction when it is not possible to determine from at least one of the processing attribute, the apparatus attribute and the data attribute whether or not an error occurs in the printing process, and a controller that displays information indicating that the error occurs in the printing process.

Upon occurrence of a paper jam at a circulation conveyer with a switching direction being set at a paper discharge guiding direction, a controller performs control of maintaining the switching direction at the paper discharge guiding direction and discharging sheets at a section of the circulation conveyer downstream of a position of the paper jam, the printing conveyer, and the paper discharger. Upon occurrence of the paper jam with the switching direction being set at a circulation guiding direction, the controller performs control of switching the switching direction to the paper discharge guiding direction after a sheet passing a switch exits the switch, and discharging the sheets at the section of the circulation conveyer downstream of the position of the paper jam, the printing conveyer, and the paper discharger.

In an electronic apparatus in which a plurality of controller chips are cascade-connected, if an error occurs in a given chip, the present invention allows at least chips on the upstream side of the error chip to share the existence of the error chip. The electronic apparatus of this invention includes a plurality of control chips which are cascade-connected. Each control chip includes a watchdog timer, and a transfer unit configured to supply, to a second another control chip positioned on the upstream side, as an interrupt signal from the watchdog timer, an OR signal of an interrupt signal generated by the watchdog timer and an interrupt signal generated by another watchdog timer in a first another control chip positioned on the downstream side.

An image processing apparatus performs recovery processing for recovering a reading error when a predetermined condition is satisfied. The image processing apparatus includes a reading unit configured to read a document, a printing unit configured to print an image of the document read by the reading unit, and a processing unit configured to perform recovery processing for recovering a reading error by the reading unit if a mode for concurrently implementing the reading by the reading unit and the printing by the printing unit is not set.

A printing apparatus, having a plurality of heads, a plurality of head controlling circuits, a master transmitter, and a determining unit, is provided. The head controlling circuits are connected to the heads in one-to-one correspondence and are connected with one another serially. Each head controlling circuit controls a corresponding one of the heads to record a part of the image based on master data. The master transmitter transmits the master data to a most upstream one of the head controlling circuits. The head controlling circuits are configured to pass the master data received by the most upstream one of the head controlling circuits serially downstream onto a most downstream one of the head controlling circuits, and generate differential data indicating a difference between the master data and read data generated by reading an image. The determining unit determines whether the image contains a defect based on the differential data.
