IMPORTANT: In most cases, substrate calibration is not recommended for OPOS. If you perform the calibration 
and results do not improve, reset the substrate calibration value to its default setting of 30 (see below).
1. Turn on the cutter and load the substrate with the calibration plot.
2.
Press  .
3.
Press  . System setup appears on the screen. Press  .
4.
Press   or   until Calibrations appears on the screen, then press   to conrm.
5.
Press   or   to scroll through the menu until you reach Cal media. Press  . Measure appears on 
the screen.
The cutter allows you to choose whether to measure the substrate or ll in a previously recorded value. 
Press   when nished.
NOTE: If a combination of substrate color and marker color has already been calibrated and recorded, 
press   and then  . Now use  , and   to enter this value directly, without having to 
measure it again. Press   to conrm.
6.
Press   again. The cutter lowers the sensor. Put the sensor on the white area appears on the screen.
7.
Use  ,  ,  , and   to maneuver the knife on top of a white area, which should be at least 3 
× 3 cm (1.2 × 1.2 in).
8.
Press   to conrm.
9.
Use  ,  ,  , and   to maneuver the knife on top of a black area, approximately in the 
middle and slightly to the bottom right.
10.
Press   to conrm. The cutter makes a circular movement while it measures the reection of the marker 
color. It briey displays the measured values and then shows a value that is characteristic for this substrate 
color and marker color combination. Store this value for future reference.
NOTE: An error message may appear if the sensor cannot dierentiate between black, grey, and white. 
Make sure the test has been performed correctly. If OPOS cannot sense the markers, one of the manual 
alignment methods must be used.
TIP: Remember to reset the calibration before printing on a standard substrate.
Adjust cutting parameters
Some parameters should be reset whenever a new substrate is loaded.
Set knife depth and pressure
1. Ensure that substrate is loaded in the cutter.
