When printer faults occur, the MultiFlow offers the possibility of executing
a so-called "loop-back test". This test enables the printer connection to be
tested for lead breakage (see chapter 5.7.2.1 "Loop-Back Test" / page
61).

be executed with any printer linked.
Remove the data cable from the printer and bridge the communications
lines.
