8.2.1 Basic Sequence of Operations

The laser scanner motor starts to rotate when the Start key is pressed (or the print request signal is issued). When its
rotation has stabilized, the printer unit becomes ready for formation of images, causing the printer side to generate
the sync signal (PTOP).
The machine uses the signal to generate the sub scanning direction signals (Y-TOP, M-TOP, C-TOP, K-TOP) for
individual colors, and turns on the lasers of the corresponding colors.
