IMAGE FORMING APPARATUS DETECTING OCCURRENCE OF JAM

摘要

An image forming apparatus includes a timing roller for conveying paper in the image forming apparatus, a first motor receiving supply of electric power from a power source for driving the timing roller, a second motor receiving supply of electric power from the power source, a sensor for detecting whether a jam occurs at the conveyance roller, a drive relay for cutting off supply of electric power from the power source to the first and second motors, if occurrence of a jam is detected, and a control circuit for controlling an operating state of the second motor such that regenerative power produced at the first motor due to rotation of the conveyance roller is supplied to the second motor, if occurrence of a jam is detected.

1. An image forming apparatus comprising:
a plurality of loads receiving supply of electric power from a power source; a conveyance roller for conveying paper; a first load that is one of the plurality of loads for driving the conveyance roller; a second load that is one of the plurality of loads and different from the first load; a jam detector for detecting whether a jam occurs at the conveyance roller; a first power cut-off unit for cutting off supply of electric power from the power source to the plurality of loads, if the jam detector detects occurrence of a jam; and a power supply unit for controlling an operating state of the second load such that regenerative power produced at the first load due to rotation of the conveyance roller is supplied to the second load, if the jam detector detects occurrence of a jam.
