A printing apparatus has first and second sheet storage units, where a second sheet conveyance path is longer than a first sheet conveyance path, and includes a determining unit and a permitting unit. When a sheet stored in the first sheet storage unit is for printing of a Nth page included in a first job and a sheet stored in the second sheet storage unit is for printing of a N+1th page included in the same first job, the determining unit determines a feeding schedule in which the N+1th page sheet feeding is initiated before the Nth page sheet feeding is initiated. When an issued instruction is issued to perform a second job by interrupting the first job after determining the feeding schedule, the permitting unit permits printing of a page included in the second job before the printing of the N+1th page included in the first job.

An image processing apparatus includes a receiving unit, an executing unit, a log information generating unit, a holding unit, and a transmitting unit. The receiving unit receives and installs one or more program information items for executing a preset process. The executing unit executes the preset process on the basis of at least one of the installed one or more program information items. The log information generating unit generates log information regarding the preset process based on the one or more program information items executed by the executing unit. The holding unit holds a transmission destination of the log information in association with each of the one or more program information items. The transmitting unit transmits the log information to the transmission destination associated with the executed one or more program information items.

Printing by determining target color values based on first color outputs, determining current color values based on current color outputs, and calculating color compensation values to compensate for a difference between the target color values and the current color values.

A printing apparatus includes a voltage supply section that supplies a charging voltage for charging a transport belt, a detection section that detects whether or not charging abnormality has occurred in the transport belt, and a determination section that determines a cause of the charging abnormality. The determination section determines that the cause of the charging abnormality is abnormality of the voltage supply section, when the movement period includes the period for which the detection section detects the charging abnormality and does not include the period for which the detection section does not detect the charging abnormality.

An image forming apparatus includes an image forming portion, an image bearing member, a transfer member, a voltage applying portion, a detecting portion, and a controller capable of executing an operation in an adjustment mode in which a chart on which a plurality of test images are transferred by stepwise changing a test voltage applied to the transfer member by the applying portion is formed on a recording material and then a transfer voltage applied to the transfer member applied by the voltage applying portion during transfer of the toner image is adjusted. The controller is capable of changing a change width per level of the test voltage applied during formation of the chart, on the basis of a detection result of the detecting portion when the voltage is applied to the transfer member when the recording material on which the chart is formed is in the transfer portion.

An image forming apparatus includes: an image forming unit configured to form an image on a sheet; a conveyance unit configured to convey the sheet having the image formed thereon to a conveyance path; a reading unit configured to read a test image of a sheet conveyed to the conveyance path; and a controller configured to: determine an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit; control the image forming unit to form the test image; control the reading unit to read the sheet having the test image formed thereon; determine an adjustment value for adjusting a geometric characteristic of an image to be formed by the image forming unit based on a reading result of the reading unit.

A motor control apparatus includes: a current supply unit configured to supply coil current to a plurality of coils of a motor by controlling, based on a first command value of excitation current and a second command value of torque current, voltage to be applied to the plurality of coils; a first setting unit configured to set the first command value; a second setting unit configured to set the second command value; and a control unit configured to use first control in starting of rotation of a rotor of the motor, and switch control to second control after rotation speed of the rotor becomes greater than predetermined speed. The first setting unit is further configured to set a value greater than 0 as the first command value before the control unit switches control from the first control to the second control.

An information processing apparatus includes a processor configured to display an operation screen for receiving an operation regarding setting information of an image forming apparatus that operates in association with the setting information with optimum values changing depending on external factors on a display device and receive an operation on the operation screen, in which the processor is configured to display a creation screen that is one of the operation screen and is used to newly create the setting information, on the display device, receive an input of a reason for creation of the new setting information on the creation screen and specify an item to be set corresponding to the received reason for creation among setting items in the setting information, and display the specified item on the operation screen to be identifiable with respect to other setting items.

A printing apparatus includes a printing section that performs printing on a medium containing calcium carbonate, a transport section that rotationally drives a transport belt that forms at least a portion of a transport path in which the medium is transported, a voltage supply section that supplies a charging voltage to a charging roller for charging the transport belt, a detection section that detects whether or not charging abnormality has occurred in the transport belt, and a determination section that determines whether abnormality has occurred in the voltage supply section or the transport belt, or abnormality has occurred in the voltage supply section and the transport belt, based on a rotation amount of the transport belt and the detection result of the detection section. The transport belt is coated with melamine resin.

A sheet processing system for automated sheet adjustment includes a sensor system which captures at least a first image of a sheet of print media as the sheet is conveyed on a main transport path between a print media supply module and a marking device of an image rendering module. A control module computes a lateral error for the sheet, based on the captured at least first image, and computes an adjustment based on the computed lateral error. A sheet transport path adjustment mechanism translates a first portion of the main transport path relative to a second portion of the main transport path, based on the computed adjustment.
