Page 95 All manuals and user guides at all-guides.com 2. Synchronization Control for the Main/Sub Scanning Direction The video signals are synchronized for the main scanning direction based on the BD signal by the video controller. The video signal after gamma correction is written to the memory for main scanning direction synchronization in response to the main scanning sync signal (HSYNC) based on the write BD signal Reading from the memory for the main scanning direction is executed based on the BD signal for Y, M, C, and Bk.
Page 96 The video signal is forced to remain ‘0’ until the print area signal (YFRM in Figure 3-411) is generated, thereby creating a leading edge margin.
