Abstract

The invention discloses a multichannel power correction control unit. An LSU enabling and line synchronous processing module can enable an LSU and various functional modules; a CTC1 signal module can generate CTC1 signals in an initialization stage and a normal work period according to configuration information, and can also transmit control information to an (n-1) path signal splitting and controlling module and receive initialized completed marks of an (n-1) path signal aliasing generator module; the (n-1) path signal splitting and controlling module receives and analyzes a preceding stage control signal, generates (n-1) path signal splitting and controlling information according to the analyzed information and transmits the (n-1) path signal splitting and controlling information to the next stage; the (n-1) path signal aliasing generator module receives a pulse signal sent from the (n-1) path signal splitting and controlling module, generates an aliasing signal and transmits the signal to the next stage; an (n-1) path automatic cycle dial-up control module receives a cycle counter transmitted by the (n-1) path signal splitting and controlling module.

Description

technical field [0001] The invention belongs to the field of laser printers, in particular to a multi-channel power correction time control device and method. Background technique [0002] At present, the LSU control unit with single laser is mainly used in the market. With the improvement of the production and manufacturing process of lasers, the laser scanning unit (LSU) of multiple lasers is ready for production. The main components of the laser emitting part of the LSU are the laser and the power correction unit. When printing the output data of the data module, the data '1' makes the laser emit light, and the data '0' makes the laser not emit light; when the laser emits light for a period of time, the power needs to be recalibrated. The time point of calibration is very important. The interference print data module controls the laser. [0003] The most important part of the control device of the existing laser emitting part of the LSU is the print head power calibrat...
