6. Check the cut pattern(s). Peel off the four outside corners of the test pattern(s) that you cut by selecting
TEST 1 or 2, and then look at the corners of the inner triangle. If the corners are rounded, the OFFSET
setting is too low. Conversely, if the corners are too pointed, the OFFSET setting is too high.
7. Next, peel off the corners of the triangle(s). Ideally, only slight traces of the cutter blade should remain on
the mediumʼs base sheet. If the base sheet has been cut through, either the FORCE setting is too high
or the cutter bladeʼs tip is extended too far. If the base sheet shows only a few traces of the cutter blade,
either the FORCE setting is too low or the cutter bladeʼs tip is not sufficiently extended.
8. Press the CONDITIONS key to display the menu for specifying the cutting conditions, then adjust
the FORCE and OFFSET settings.
9. Repeat Steps (3) through (8) until you achieve satisfactory test results.
10. When satisfactory test results are achieved, press the
plotter to READY status.
