9Ć8 Product History and Service Notes C3187Ć90000
All the part numbers associated with both A.01.00 implementations are obsoleted and
replaced by A.01.01 part numbers.
Usage of a DIPĆ40 ICĆextracting tool or similar is highly recommended to prevent damage to
the Main PCA traces.
Note that firmware version A.01.01 is available only on EPROMs. Make sure that proper
ESD safety procedures are followed and that the devices are correctly plugged into their
sockets, leaving the rightmost pair of holes free.

Bug Fixing
RTL: Fix bitmap on negative YĆcoordinates. (Jail effect)
STARSHIP: PJL enter language = HPGL/2 was going back to HPGL; now goes to HPGL/2.
REPLOT: Replot clips last swath. When doing replot (same size as the original plot),
sometimes the last swath of the plot is clipped. This is because the mediaĆload sheet length
measurement is not exact, so the plotter recognizes the sheet as shorter than it actually is.
Fixed by increasing the tolerance on sheet length before clipping by 0.15 in. when replotting.
The previous tolerance was only 1/1200 in.
CANCEL: In firmware versions A.01.01 (DesignJet 200) and B.02.00 (DesignJet 220) the
user could not cancel while plotting nonĆflowĆmode plots (plots that don't exceed maximum
memory available in plotter). Fixed.
This firmware is not yet available at the time of printing of this manual.
