As an alternative, an angular position of the circle segment is adjustable and its value is determined by a time signal corresponding to the actual time. Several circle segments may be displayed corresponding to multiple print jobs in the queue or to the estimated processing time of various printers executing a print job. Two circle segments may also be utilized to separately display the number of hours and the number of minutes in the estimated processing time. The circle segments may also be utilized to manipulate the sequence in the print queue by simply selecting and dragging a circle segment to a desired position in the queue.

Inventor: YAMAMOTO SHUUHEI
IPC: G03G21/00
Filed: 1998-10-27
Abstract: An excellent image forming state is secured constantly regardless of the history of an image forming unit installed.      When a new drum cartridge is installed in a copying machine during a standby pending operation of a copy switch on a control panel, CPU reads the number of rotations of a photoreceptor drum from a memory of the drum cartridge, and updates a count of a counter C with the number of rotations read. When the copy switch is operated, CPU derives a grid voltage corresponding to the count of counter C from a relationship between the number of rotations of photoreceptor drum and the grid voltage of the electrostatic charger pre-stored in ROM, executes an image forming process by setting the grid voltage derived from a high-voltage source, and adds the number of rotations of photoreceptor drum made in the current image forming process to the count of counter C.
