Pen Offset (2-Pen Models Only); Setting Procedure - GRAPHTEC FC7000 Series User Manual

7.4 Pen Offset (2-pen models only)

The PEN OFFSET function is used to determine the corrective values you should
input in order to adjust the precision between PEN 1 and PEN 2. The pen mounted
in the pen holder attached to the pen carriage is PEN 1, and the pen mounted in
the pen station is PEN 2.

ETTING ROCEDURE
Mount a cutter-pen or a plotting pen in the pen holder and a plotting pen in the
pen station, and then turn on the power.
Press the MENU key.
The following menu appears. Press the NEXT key.
Press the F4 key (OPTION 2). The following menu appears.
Press the F1 key (PEN OFFSET ADJ. ). The following menu appears.
Use the POSITION keys to move the pen carriage into position to plot the first
cross mark. Press the F3 key to select TEST PATTERN. The plotter plots the
first cross mark using PEN 1 and then plots another cross mark using PEN 2.
(In this case, Condition number 1 was used for PEN 1 and Condition number 2
for PEN 2 to perform cutting/plotting. Measure the distance between the two
plotted cross marks.

Press the F4 key (PARAMETER SET) in the menu displayed in Step 6. The
following menu appears.
Add the values measured in Step 6 to the displayed values. The corrective
values that need to be input depend on the actual shift in position between the
PEN 1 and PEN 2 cross marks. In the above figure, for example, there is a shift
in both the -X and -Y direction, and so X = -*.* mm and Y = *.* mm need to be
input. Press the F3 or F4 key to select the X or Y axis. Use the (
POSITION keys to increase or decrease the value. Press the ENTER key to
register your setting. Press the NEXT key to cancel the setting.
Return to Step 6 to check the offset. If there is still an offset, repeat Steps 7
and 6.
This setting is retained in the plotter's internal memory even when the power is
turned off.
