Abstract
An image forming apparatus is provided that is aimed to control adverse impacts on a printing quality caused by the meandering motion of a printing belt and changes of a feeding speed. The image forming apparatus includes: one or more printing portions that print a printing object on paper; a belt in a form of a loop, the belt serving to transport the paper to a printing position; a roller that feeds the belt; a phase detector that detects a phase of the belt; a behavior detector that detects a behavior of the belt; a controller that decides a paper setting position on the belt based on the behavior of the belt for each phase; and a paper feeder that transports the paper to the paper setting position.
Claims20
An image forming apparatus, comprising:
- one or more printing portions that print a printing object on paper;
- a belt in a form of a loop, the belt serving to transport the paper to a printing position;
- a roller that feeds the belt;
- a phase detector that detects a phase of the belt;
- a behavior detector that detects a behavior of the belt;
- a controller that decides a paper setting position of a location on the belt where the paper is to be positioned based on the behavior of the belt for each phase;
- and
- a paper feeder that transports the paper to the decided location on the belt based on the behavior of the belt for each phase.
A control method for an image forming apparatus, the control method comprising:
- detecting a phase of a belt in a form of a loop, the belt serving to transport paper to a printing position;
- detecting a behavior of the belt,
- deciding a paper setting position on the belt based on the behavior of the belt for each phase;
- and
- transporting the paper to the paper setting position decided.
