1. In outline diagrams,
represents mechanical drive paths,
and
indicates electrical signal paths.
2. Signals in digital circuits are identified as '1' for High and '0' for Low. The
voltage of signals, however, depends on the circuit.
Nearly all operations of the machine are contorolled by microprocessors; the
internal workings of these processors are not relevant to the service person's work
and, therefore, are left out of the discussions. By the same token, no repairs are
prescribed for the PCBs at the user's premises; for this reason, PCBs are
discussed by means of block diagrams rather than circuit diagarams.
For the purpose of explanation, discussions are divided into the following: from
sensors to finisher controller PCB input ports; from finisher controller output ports to
loads; and minor control circuits and functions.
