IMAGE FORMING APPARATUS, FRONT-BACK MAGNIFICATION CORRECTION METHOD, AND COMPUTER PROGRAM PRODUCT |
摘要 |
An image forming apparatus includes: an edge detection unit that detects one edge, in a conveyance direction, of a conveyed sheet; a passing detection unit that detects passing of the one edge; a judging unit that judges whether the edge detection unit or the passing detection unit has detected the one edge, within a predetermined monitoring time after the edge detection unit or the passing detection unit detected the one edge; a notifying unit that gives a notification indicating that front-back magnification correction is difficult to perform on the sheet when the judging unit has judged that the one edge is not detected within the monitoring time; an acquiring unit that acquires a desirable front-back magnification correction value input via an input unit according to the notification; and a correction unit that performs a front-back magnification correction process on the sheet, using the acquired front-back magnification correction value. |

1. An image forming apparatus comprising:
an edge detection unit that detects one edge, in a conveyance direction, of a sheet conveyed by a conveyance mechanism; a passing detection unit that detects passing of the one edge of the conveyed sheet; a judging unit that judges whether the edge detection unit or the passing detection unit has detected the one edge, within a predetermined monitoring time after the edge detection unit or the passing detection unit detected the one edge; a notifying unit that gives a notification indicating that front-back magnification correction is difficult to perform on the sheet when the judging unit has judged that the one edge is not detected within the monitoring time; an acquiring unit that acquires a desirable front-back magnification correction value input via an input unit according to the notification by the notifying unit; and a correction unit that performs a front-back magnification correction process on the sheet, using the acquired front-back magnification correction value. |
