8Ć16 Troubleshooting C3187Ć90000
Ink Smearing
Add Starwheel Mount
Ink may smear in DesignJet 200 plotters and early DesignJet 220 plotters due to cockle in
the media caused by the geometry of the media path. The problem is more evident when
loading A/A4Ćsize media. (Solution D chapter 9, w Change in Bail and Overdrive Parts.)
Change Carriage Rear Bushing
Another reason for ink smearing in DesignJet 200 plotters is an insufficient distance between
the cartridges and the media. This problem is solved in the DesignJet 220 plotters, using a
new rear bushing on the cartridge carriage. You can order this bushing for a DesignJet 200.
(Part number D chapter 10.)
Plots Joined or Not Plotted
HPĆGL Timeout
If the user is using an
HP 7586B
(HPĆGL) driver, it may not end files properly with the result
that several plots may be joined, or not plotted at all. In this case you need to choose an
HP
Ć
GL Timeout
period. (Instructions D User's Guide.) The timeout tells the plotter how long
to wait before assuming a plot is complete.
Short timeout period: A timeout setting that is too short results in incomplete plots.
Long timeout period: If the plotter has finished receiving the plot data (
Busy
LED stops
flashing and remains on) and is waiting for the timeout period to finish before plotting, you
can command it to plot immediately by pressing
Form Feed
.
Incompatibility between Trailing Cable and Main PCA
The shielded trailing cable C3180Ć60033 (blue and white) is NOT compatible with old main
PCAs (C3180Ć60101, C3180Ć68101, C3180Ć69101). Nothing is printed if you use them in
combination. Update the main PCA.
Incorrect Line Widths
DesignJet 200 plotters with firmware version A.01.00 may plot line widths that are
inconsistent with the selected values if an IN command is absent in the plot files. Update the
firmware. (Details D chapter 9, w Problems Corrected by Firmware Release A.01.01.)
