9Ć14 Product History and Service Notes C3187Ć90000
Change in Carriage
Early DesignJet 200 plotters were manufactured with the following cartridge carriage:
D Cartridge Carriage, C1633Ć60120 (including Carriage PCA, C2847Ć60103), now obsolete.
Later DesignJet 200 plotters, and DesignJet 220 plotters, have a new cartridge carriage:
D Cartridge Carriage, C2847Ć60071 (including Carriage PCA, C2847Ć60125).
The new carriage is not compatible with the DesignJet 200 firmware revision A.01.00. In
combination, they destroy the cartridges. If you install a new carriage, ensure that the
firmware revision of the EPROMs or masked ROMs on the main PCA is later than A.01.00.
Later firmware revisions can be installed with either carriage.
Change in Bail and Overdrive Parts
DesignJet 200 plotters, and early DesignJet 220 plotters, were manufactured with 9
starwheel mounts on D/A1Ćsize models, and 13 starwheel mounts on E/A0Ćsize models.
To reduce the risk of the mediaĆpath geometry sometimes causing media to cockle and ink to
smear, later DesignJet 220 plotters include an extra starwheel mount towards the rightĆhand
side of the bail. (The problem was greatest when loading A/A4Ćsize media.)
If you are ordering a new bail, overdrive roller or overdrive enclosure, ensure that you order
the appropriate part corresponding with the number of starwheel mounts on the plotter. A
service rework kit is available if you need to replace all 9Ć or 13ĆstarwheelĆmount parts with
10Ć or 14ĆstarwheelĆmount parts respectively. (Part numbers D page 10Ć24b.)
