2.5 How to Make Sure the Sign Has the Correct Size
(Length Calibration)
The SummaCut cutters are friction-feed machines. This means that the cutting length
is dependent on the thickness of the material.
The cutters have been calibrated in the factory for standard 2-mil cast or 3-mil
calendared vinyl. Each user (the SummaCut has a total of 4) can hold a different
calibration factor.
This is very helpful for multi-colored signs; it ensures that the parts in different colors
match up, even if different types of vinyl media are used.
NOTE: For standard use, it is not necessary to calibrate the machine. With standard
vinyl the accuracy is within 0.2%. However if high accuracy between different vinyl or
colors is needed, then calibration is necessary.
Calibrating the media (Length calibration):
1. Power on the cutter, load media, and mount knife (see section 1).
NOTE: The wider and longer the loaded media, the more accurate the calibration will
be. Use a piece of vinyl of maximum width and a length that is approximately 1.5
times the width.
2. Press .
‘Velocity’ will appear on the LCD.
3. Press

‘Calibrate X/Y’ will appear on the LCD.
6. Press
.
The cutter will reload the media and perform the length calibration test. Take out
the media and measure the length of the cut line with a ruler (measuring device).
The length that has to be entered is the distance between line 1 and line 2 as
shown in the figure.
