Introduction
This chapter describes the differences between earlier versions of the plotters and the latest version documented in this manual.
Serial2Number Format
The plotter serial number is composed of 10 letters and digits, for example ESA4800248.
DIn 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.
DIn 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.
DIn 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.
DIn 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.
DThe remaining five digits distinguish the plotter from others manufactured in the same country in the same month. In the example above, these are 00248.
