8.2.1 Basic sequence of operation

The laser scanner motor starts to rotate when the Start key is turned on (or, in response to the print requset
signal). Thereafter, when the rotation has stabilized, the printer unit becomes ready to form images, indicating
the fact by its 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.
