Clean the substrate sensor
Over time, the substrate sensor may become dirty with accumulated residue from the substrate, which may 
cause the cutter to malfunction.
Clean the sensor by wiping it with a cotton swab.
Clean the Y-guide rail
There are two V-shaped areas on the Y-guide rail on which the tool carriage slides from left to right. The areas 
are on the top and on the bottom of the front of the Y guide.
Although the shape of the Y-guide rail may dier from model to model, the areas are located in the same place 
at the top and bottom of the guide.
The illustration below shows the top of the Y guide.
Over time, there may be some accumulated residue on these sliding surfaces and on the rollers of the tool 
carriage.
Clean the sliding surfaces
1. Turn o the cutter.
2. Take a soft cloth, dampened with isopropyl alcohol or mild detergent.
NOTE: If you are in an area (such as California) that regulates VOC cleaning and maintenance uids, 
instead of isopropyl alcohol use a VOC-certied cleaner such as a properly diluted Simple Green All-Purpose 
Cleaner.
3. Clean the surfaces. When the tool carriage is in the way, push it gently to the left or right.
