Abstract

The invention provides a printing control apparatus, a method, and an image forming apparatus. A first detection unit in printing control equipment determines the operation state of a laser scanning unit LSU and the operation state of a program in a main control processor; and an exception processing unit connected with the first detection unit is used for processing the exceptions according to the running states of the LSUs indicating the exceptions or the running states of the programs in the master control processor indicating the exceptions. And the LSU is controlled to stop running, so that the reliability of the printing process is improved, the possibility of safety problems caused by heating of the LSU during working in an abnormal running state is reduced, and the printing safetyis further improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing control device, method and image forming device. Background technique [0002] During the printing process of various image forming devices such as printers, if a laser scanning unit (Laser Scanning Unit, LSU for short) is abnormal, it is necessary to control the LSU to stop working in time to improve the safety of the printer. [0003] In some existing technologies, the main control processor of the printing software monitors the feedback signal of the LSU, and sends a stop command to the LSU when the software program of the main control processor determines that the feedback signal is abnormal. The LSU will stop working only when it receives a stop command. [0004] However, if the main control processor runs abnormally or is delayed, the stop command cannot be issued in time. The LSU continues to work before receiving the stop command, which causes the LSU to hea...
