The Laserpoint 3 went through a sizeable change in their internal design in early 2019, so our Parts on USCutter.com are separated by model age, determined by the first three characters on the serial number sticker on your machine, located on the Left-side Endcap, next to the power switch.
In this case, the Serial number for this Laserpoint 3 is 19OTC33AD0023. For the purposes of figuring out which model you have: 195 or greater vs. 194 or less, you look at the first three characters of the serial number.
In this case, the first three characters are 19O. These refer to the date that the machine was manufactured, so if you see 19O, 19N, or 19D, those all count as being greater than 195.
