OPERATIONAL VERIFICATION
DesignJet 650C plotters contain several types of internal operational checks and tests to en-
sure that the plotter is properly functioning and to help identify problems if any are detected.
POWER-ON SELF-TEST
Whenever the plotter is switched ON, it automatically performs a series of internal self-tests
and initialization sequences which check the basic electrical and mechanical functions of the
plotter. Among the items checked are the processors, motors and sensors. If an error is de-
tected, a message or system error code will be visible in the front panel display. Error codes
and messages are presented in Chapter 8 of this manual. Self tests are listed in Chapter 8.
DEMONSTRATION PLOT
Two demonstration plot samples are resident in the HP DesignJet 650C plotters. Proper plot-
ter operation can be checked through use of the demo plots. The demo plots show different
plotter capabilities including pen line widths and shading. The demo plot can be set to plot in
any of the available front panel languages.
