Introduction
This chapter describes the differences between earlier versions of the plotters and the latest
version documented in this manual.
SerialĆNumber Format
The plotter serial number is composed of 10 letters and digits, for example ESA4800248.
D In the first two positions is the code for the country of manufacture of the plotter. In the
example above, this is ES, which is the code for Spain.
D In the third position is the revision letter of the plotter. The letter A identifies the
original version of the plotter. The next revision would have the letter B and so on. All
DesignJet 200 plotters have revision letter A. The original version of the DesignJet 220
also has revision letter A.
D In the fourth position is the last digit of the year of manufacture. This is 4 for plotters
made in 1994, as in the example above.
D In the fifth position is the month of the year. (October is represented by the letter A,
November by B, and December by C.) In the example above, the digit is 8, that is,
August.
D The remaining five digits distinguish the plotter from others manufactured in the same
country in the same month. In the example above, these are 00248.
