Disabling The Plotter; Changing Pens - HP 250 Operating

Graphics Devices
Disabling the Plotter
To disable the plotter:
SINGLE PEN PLOTTERS - Carefully push the CHART LOAD pushbutton
so that the RESET button is not pushed. The CHART LOAD lamp
will go on and the plotter will be disabled from receiving any
data from the computer. First change the pens and then the
paper, turning off the CHART LOAD lamp as the last operation.
If you choose to smooth down the paper after turning off the
CHART LOAD lamp, do it at your own risk after making sure that
no system user is sending data to your plotter. If your
application program is running, it will supply some safe-
guards.
FOUR and EIGHT PEN PLOTTERS - Push the STBY (STANDBY) switch
to cause the standby lamp to go on steadily. You should do
this only when plotting has stopped because any data in the
plotter will be purged by this operation. With the STANDBY
lamp on, you may change pens and paper safely in any order.
When ready to resume plotting, push the ON LINE button twice
to cause the lamp to blink steadily and check that the CHART
LOAD lamp is off.
Changing Pens
HP offers a variety of pens including are narrow tip (0~3 mm) and
wide tip (0.6 mm or 0.7 mm) pens for paper and overhead
transparency film in a variety of colors.
The most commonly used pens are the narrow line (0.3 mm) paper
pens in black, red, green, and blue colors; you should ensure
that a supply of these pens are kept in stock.
T.he procedure for loading and changing pens differs for the
single pen and multiple pen plotters. In both cases the plotter
should be disabled as explained above before performing the
operation.
Single Pen Plotters:
1. Disable the plotter by turning on the CHART LOAD lamp.

carrier ring with the other hand.
