Abstract

Official abstract text for this publication.

A control device for an image forming apparatus that transitions to a restricted mode which is a print mode to alternately transition between a printable state to perform a print operation, in which a predetermined print amount is printable, and a sleep state to stop a subsequent print operation for a predetermined sleep time after the print operation is performed, includes a print-operation determiner and a print controller. The print-operation determiner determines, when a print-operation execution request to the image forming apparatus is received in the sleep state, whether the image forming apparatus is to perform the subsequent print operation based on a print amount of the print-operation execution request. The print controller controls the subsequent print operation of the image forming apparatus according to a determination result of the print-operation determiner as to whether the image forming apparatus is to perform the subsequent print operation.

First claim

Opening claim text (preview).

What is claimed is: 1 . A control device for an image forming apparatus that transitions to a restricted mode which is a print mode to alternately transition between a printable state to perform a print operation, in which a predetermined print amount is printable, and a sleep state to stop a subsequent print operation for a predetermined sleep time after the print operation is performed, the control device comprising: a print-operation determiner to determine, when a print-operation execution request to the image forming apparatus is received in the sleep state, whether the image forming apparatus is to perform the subsequent print operation based on a print amount of the print-operation execution request; and a print controller to control the subsequent print operation of the image forming apparatus according to a determination result of the print-operation determiner as to whether the image forming apparatus is to perform the subsequent print operation. 2 . The control device according to claim 1 , wherein, when the print amount of the print-operation execution request is equal to or less than the predetermined print amount, the print-operation determiner determines that the image forming apparatus is to perform the subsequent print operation. 3 . The control device according to claim 1 , wherein, after the image forming apparatus performs the subsequent print operation in the sleep state, the print controller controls a further subsequent print operation of the image forming apparatus to change the sleep time to be longer than a time length having been set before the subsequent print operation. 4 . The control device according to claim 1 , wherein, after the image forming apparatus performs the subsequent print operation in the sleep state, the print controller controls a further subsequent print operation of the image forming apparatus to change the sleep time to be longer than a time length having been set before the subsequent print operation by a difference between the time length and an elapsed time from a transition to the sleep state until the subsequent print operation is performed, and the sleep time. 5 . The control device according to claim 1 , further comprising: an elapsed-time counter to measure an elapsed time after the image forming apparatus transitions to the restricted mode; a print amount counter to measure a cumulative print amount of the image forming apparatus after the image forming apparatus transitions to the restricted mode; and a unit-print-amount calculator to calculate, based on the measured elapsed time and the measured cumulative print amount, a unit print amount which is a print amount per unit time after the image forming apparatus transitions to the sleep state, wherein when the print-operation execution request is received while the image forming apparatus is in the sleep state, the print-operation determiner determines, based on the unit print amount calculated by assuming that the print-operation execution request is performed, whether the image forming apparatus is to perform the print operation. 6 . The control device according to claim 5 , wherein, when the print-operation execution request is received while the image forming apparatus is in the sleep state, the print-operation determiner determines that the image forming apparatus is to perform the print operation if the unit print amount calculated by assuming that the print-operation execution request is performed is equal to or less than a predetermined unit print amount. 7 . The control device according to claim 5 , wherein, when the image forming apparatus is cancelled from the restricted mode, the print controller clears the measured elapsed time and the measured cumulative print amount to zero. 8 . The control device according to claim 5 , wherein when the print-operation execution request is received while the image forming apparatus is in the restricted mode, the print-operation determiner determines, based on the unit print amount calculated by assuming that the print-operation execution request is performed, whether the image forming apparatus is to perform the print operation. 9 . A non-transitory recording medium storing a control program for causing an image forming apparatus that transitions to a restricted mode which is a print mode to alternately transition between a printable state to perform a print operation, in which a predetermined print amount is printable, and a sleep state to stop a subsequent print operation for a predetermined sleep time after the print operation is performed, to execute: determining, when a print-operation execution request to the image forming apparatus is received in the sleep state, whether the image forming apparatus is to perform the subsequent print operation based on a print amount of the print-operation execution request; and controlling the subsequent print operation of the image forming apparatus according to a determination result as to whether the image forming apparatus is to perform the subsequent print operation. 10 . A method for controlling an image forming apparatus that transitions to a restricted mode which is a print mode to alternately transition between a printable state to perform a print operation, in which a predetermined print amount is printable, and a sleep state to stop a subsequent print operation for a predetermined sleep time after the print operation is performed, the method comprising: determining, when a print-operation execution request to the image forming apparatus is received in the sleep state, whether the image forming apparatus is to perform the subsequent print operation based on a print amount of the print-operation execution request; and controlling the subsequent print operation of the image forming apparatus according to a determination result as to whether the image forming apparatus is to perform the subsequent print operation.
