An apparatus includes a specifying unit that specifies a color; an input unit that inputs an image; a converting unit that converts a color in the image, which has a hue within a predetermined range with respect to the specified color, into a color of a predetermined hue and converts a color in the image, which has a hue outside the predetermined range with respect to the color, into black; a printing unit that prints the image subjected to the converted color; and a counting unit that separately counts a number of sheets when the printed image includes the color of the predetermined hue and a number of sheets when the printed image does not include the color of the predetermined hue.

According to one embodiment, an image forming apparatus includes, a sheet transporting unit, a scanner, a print unit, an input device, a counter, and a control unit. The sheet transporting unit transports a predetermined number of sheets among a plurality of the sheets. The scanner reads the sheets which are transported by the sheet transporting unit as image data. The print unit prints the image data which is read by the scanner. The input device receives an input from a user. The counter counts the number of the transported sheets. The control unit controls the sheet transporting unit and the print unit depending on the number of the transported sheets and the number of sheets which are input by the user.

A print job received by a printing system has subsets of items. Multiple items are printed on each sheet. Finishing devices of the printing system are limited to processing a single subset of the items at a time, causing printing devices to wait skipped-pitch delays. An unadjusted number of machine-hours to complete the print job is determined based on continuous printing without interruption. A skipped-pitch delay is assigned to each of the subsets of items based on the number of sheets used to print each of the subsets of items. A revised number of machine-hours to complete the print job is calculated by adding the total skipped-pitch delay for the print job to the unadjusted number of machine-hours. The number of the printing devices and the finishing devices to use to complete the print job is determined based on the revised number of machine-hours.

An image forming apparatus, having a recorder, a display, an input interface, a memory, and a controller, is provided. The controller is configured to control the recorder to consume colorant to print images on sheets, count a consumption value and a quantity of the sheets consumed, determine an average usage value based on the consumption value and the quantity of the sheets, obtain a filled amount value and determine a first printable quantity, determine a second printable quantity, control the display to display a first screen including a first object indicating the first printable quantity in the display, control the display to display a second screen including a second object indicating the second printable quantity in the display, and control the display to display a screen including a third object, through which one of the first object and the second object to be displayed in the display is selectable.

The control unit controls the sheet transporting unit and the print unit depending on the number of the transported sheets and the number of sheets which are input by the user.

A server including instructions to perform a method for managing replacement of a consumable in an imaging device, which includes, determining a remaining life of a consumable installed in the imaging device; determining an average number of pages printed in the imaging device during a predetermined period; identifying a number of days of use remaining based upon a rated life of the consumable, the remaining life of the consumable, and the average number of pages printed; and determining whether the number of days of use remaining is within a predefined floor range. Upon at least one of a determination that the number of days of use remaining is within a predetermined threshold and that the remaining life of the consumable is within a predefined floor range, an order for a replacement consumable for the imaging device is created and placed in an order fulfillment system.

According to one embodiment, there is provided a method for auditing shredding data including first count information in a system for auditing shredding data. The audit method includes causing a paper sheet processing apparatus to generate a first MAC based on the first count information using a first MAC generation key, causing the paper sheet processing apparatus to transmit the first count information and the first MAC to a first computing unit, causing the first computing unit to obtain second count information based on the first MAC using a second MAC generation key, causing the first computing unit to compare the first count information and the second count information, and determining an audit result.

A management system includes a printing apparatus replaceably holding a first and a second replaceable item, and a management server. The printing apparatus includes a transmission unit that transmits identification data indicating identification information on the printing apparatus and data including a value related to a usage amount of the second replaceable item. The management server includes an acquisition unit that acquires a value related to a previous usage amount of the second replaceable item from a memory based on the identification data from the printing apparatus. The management server includes a determination unit that makes a determination about a delivery instruction of the first replaceable item based on the value related to the usage amount of the second replaceable item, which is transmitted from the printing apparatus, and the value related to the previous usage amount of the second replaceable item, which is acquired from the memory.
