The through-path mechanism is used to move paper to the duplexing feed assembly after fixing (and after the paper has been moved to the reversing assembly by
the work of the reversing flapper).
The machine is designed to reorder pages in its memory for printing, being free of the need to print originals in sequence and being, therefore, able to reduce the
time during which paper is kept on hold, ultimately bringing about faster duplexing operation. As many as 2 sheets of paper may exist at once between the regis-
tration sensor and the duplex paper sensor.
SERVICE MODE:
