Belt controller, image forming apparatus, image forming method, and recording medium storing image forming control program

摘要

A belt controller, an image forming apparatus, a belt controlling method, and a recording medium storing an image forming control program adjust a position of a belt. Each of the belt controller, the image forming apparatus, the belt controlling method, and the recording medium storing an image forming control program detects a position of the belt and transmits a position detection signal, determines whether a degree of misalignment of the belt is equal to or greater than a specified threshold before the belt starts moving based on the position detection signal, presses the belt to reduce the degree of misalignment of the belt when the degree of misalignment of the belt is equal to or greater than the specified threshold, and performs feedback control to adjust the position of the belt according to the degree of misalignment of the belt after pressing the belt.

主权项

1. A belt controller that adjusts a position of a belt, the belt controller comprising:
a position detector to detect a position of the belt and transmit a position detection signal; and a determining device configured to determine a degree of misalignment of the belt based on the position detection signal; the determining device configured to cause a motor driver to initiate a tilt of the belt independent of feedback control when the degree of misalignment exceeds a threshold to reduce the degree of misalignment before rotation of the belt is initiated, and to initiate feedback control that positions the belt based on the degree of misalignment when or after rotation of the belt is initiated.
