CAUTION:
When the plotter is turned back on, the pen position becomes the plot area’s origin ( 0, 0 ) and
the plotter is not initialized.
Unless the plot area is set, the cutting mat may be damaged and a position error may be caused
by the pen block striking the side plate.
(3) If a panel key’s corresponding bit does not properly change status, check the following.
• Fault in D1 or D2 on the Key Relay Board; or they may be attached in reverse
• Improperly connected cable. Reconnect the cable and then run this test again
• Initialize the non-volatile RAM
