Embodiment approach 1

[0057] Figure 8 It is a timing chart for explaining the processing operation of Embodiment 1, and a diagram showing data showing head consumption current.

[0058] First, the print data created by the application of the host device 28 is sent from the host device 28 to the reception control unit 4 via LAN or USB as described above, and then transferred to the memory 9 (standard RAM 9a), and the printing data is executed under the control of the MPU 11. Command analysis to generate drawing data.

[0059] The above drawing data is processed at the beginning of the page at the timing when the vertical synchronization signal (VSYNC) is output (at low level), and is processed as follows Figure 8 The printing process is performed at the indicated timing. That is, first, the download signal is output from the head control signal generator 37 at the timing a shown in the figure. The output timing of this download signal is carried out simultaneously in each station of Y, M, C, K,...

Embodiment approach 2

[0070] Figure 9 It is a timing chart for explaining the processing operation of Embodiment 2, and a diagram showing data showing head consumption current.

[0071] In addition, in the description of this embodiment, the above-mentioned figure 2 The control system of the shown color printing device 1, and figure 1 The basic configuration of the head control unit shown is also the same as that of the first embodiment described above.

[0072] Similar to the above, firstly, the print data created by the application of the host device 28 is sent from the host device 28 to the reception control unit 4 via LAN or USB as described above, and then transferred to the memory 9 (standard RAM 9a), and is controlled by the MPU11. Command analysis of print data is performed to generate drawing data.

[0073] The above-mentioned drawing data is subjected to page start processing at the timing of outputting the vertical synchronizing signal (VSYNC) (turning to low level), as follows F...

Abstract

The present invention relates to a color printer and particularly to a color printer reducing power consumption and complying with international criteria ensuring sustained earth environment. In a color printer having multiple optical writing heads for individual recording colors, the activated periods of individual color recording heads are set to different periods and one writing period of individual recording heads is divided into multiple periods, video data for recording one dot line are divided into multiple blocks in the main scan direction, and the divided video data are used for emission at different times in the sub-scan direction, whereby a smaller number of optical writing elements are simultaneously driven for emission and the peak power consumption of the entire apparatus is reduced.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2010-119178 filed on May 25, 2010, the entire content of which is incorporated herein. technical field [0002] The present invention relates to a printing device, and more particularly to a tandem color printing device using an electrophotographic method. Background technique [0003] For a tandem printing device using an electrophotographic method, image forming units such as yellow (Y), magenta (M), cyan (C), and black (K) are used, and by using The internal recording head exposes the peripheral surface of the photosensitive drum according to the printing data to form a toner image, and transfers the toner image to the recording medium to perform printing processing. Therefore, when performing color printing, a large power is required to simultaneously drive the recording heads of the respective colors. [0004] Figure 10 It is a diagram for explaining conventional control, and is for explain...
