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 medium’s base sheet. If the base sheet has been cut through, either the FORCE
setting is too high or the cutter blade’s 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 blade’s tip is not
sufciently extended.
(8) Press the CONDITIONS key to display the menu for specifying the cutting conditions, then
