The EEROM should only be cleared in the event of a checksum failure. Otherwise the

EEROM should never be cleared.

After clearing the EEROM, switch the plotter OFF and ON again without any media

loaded and perform the following calibrations in the order listed:

1 Drop detect calibration ' page 7Ć4.

2 Line sensor calibration ' page 7Ć5.

3 Accuracy calibration ' page 7Ć6.

It is recommended that a configuration plot is printed from the Utilities" menu for

setup reference. You will also need to reconfigure the frontĆpanel settings.
