Identifying a Printed Circuit Assembly

DesignJet 200 and DesignJet 220 PCAs have the following major identification features:

Part Number

PCAs having the same part number are directly interchangeable. If a PCA is revised in any way that makes it non9interchangeable with previously issued PCAs of a particular part number, a new part number is assigned to the revised PCA.

Rev￿s￿on Letter

This letter identifies the most recent revision to the etched circuit pattern. The original issue is identified with the letter A. If the master artwork for a printed circuit board is revised in order to alter performance or manufacture, the revision letter is changed to the next letter in the alphabetical sequence.

F￿rmware Rev￿s￿on Code

The firmware revision code is printed on the EPROMs or masked ROMs on the main PCA, for example B.02.01. This code is also printed by the plotter on the setup sheet and on the service configuration plot.

The DesignJet 200 old firmware revision A.01.00 is not forward C A U ￿ ￿ O N compatible with the new carriage C2847960071 (carriage PCA

C2847960125). In combination they destroy the cartridges.

The DesignJet 200 old main PCA C3180960101 is not forward compatible with the new shielded trailing cable C3180960033 (colored blue on one side).
