Basic Operation - Printronix L5000 Series Maintenance Manual

Basic Operation

After initializing (due to turning on the power or receiving an initialization request
from the printer), the power stacker enters into the following main loop and
repeatedly executes the various subroutines. However, the actuator driving
subroutines are selectively executed only upon the power stacker receiving execution
commands from the printer. The timing for driving the various actuators is
determined by the page last raster signal (LSCA) from the printer, based on the paper
head and tail status setting.
