Wind the ribbon tight again with the little plastic knob, and it’s all set to go.
You may notice a sticker with the words EXCHANGE TIMES pasted on the
ribbon cartridge. This is a remnant of an early plan to refill the cartridges when
the ribbon wears out. That idea was abandoned, at least for the time being.
Matching the Printer to the Computer
At this point, a decision should be made. If the information we need isn’t
available, we’ll decide to defer the decision. Isn’t that how all good bu-
reaucracies work?
Some computers, like the Apple, tell the printer to roll the paper up one line
each time the print head returns to the left after printing a line. Technically, we
say each CR (Carriage Return) is accompanied by an LF (Line Feed).
Other computers, like the TRS-80, rely on the printer to know enough to insert
its own LF when it receives a CR. Either way is just fine with the MX-70 since it
can be wired either way.
