Abstract
An image forming device comprising: a tray in which multiple number of sheets are stored; a feeder that feeds the sheet stored in the tray; and a hardware processor that: measures a carrying speed of the sheet fed by the feeder; determines whether or not the measured carrying speed is affected by the following sheet; corrects the carrying speed upon determining the carrying speed is affected by the following sheet; and detects a wear status on the feeder based on the measured carrying speed or the corrected carrying speed.
Claims23
An image forming device comprising:
- a tray in which multiple number of sheets are stored;
- a feeder that feeds one of the sheets stored in the tray;
- and
- a hardware processor that:
- measures a carrying speed of the sheet fed by the feeder;
- determines whether or not the measured carrying speed is affected by a following sheet;
- corrects the carrying speed upon determining the carrying speed is affected by the following sheet;
- and
- detects a wear status on the feeder based on the measured carrying speed or the corrected carrying speed.
A paper feeding mechanism deterioration determining method to determine a deterioration of a paper feeding mechanism, the method applied at an image forming device provided with the paper feeding mechanism that feeds a sheet, the method comprising:
- measuring a carrying speed of the sheet fed by the paper feeding mechanism;
- determining whether or not the measured carrying speed is affected by a following sheet;
- correcting the carrying speed upon determining that the carrying speed is affected by the following sheet;
- and
- detecting a wear status on the paper feeding mechanism based on the measured carrying speed or the corrected carrying speed.
A non-transitory recording medium storing a computer readable program to be executed by a hardware processor in an image forming device provided with a paper feeding mechanism that feeds a sheet, the hardware processor executing the computer readable program to perform:
- measuring a carrying speed of the sheet fed by the paper feeding mechanism;
- determining whether or not the measured carrying speed has been affected by a following sheet;
- correcting the carrying speed upon determining the carrying speed is affected by the following sheet;
- and
- detecting a wear status on the paper feeding mechanism based on the measured carrying speed or the corrected carrying speed.
