and a five digit suffk (for emple:
0000JOOOOO). The prefk is used to indicate year and week
of manufacture. The letter designates the country in which the printer was manufactured ("J"
indicates Japan, for e~mple).
The suffii is a sequential number incremented for each printer
produced.
For both printers, the power rating is lomted on a plate nefi to the Power Switch (see Figure l-l).
