Can I just ask what is the manufacture date of all of your lasers and how long have you had your machines? Is a 2.5 year old laser in a (supposedly) brand new machine normal? Thanks.
I received my K40 in early October 2015 & I’ve just checked the laser tube & found that it has absolutely no details at all on it. Just one sticker that has a barcode & says something about “Do not tear up” (can’t read it all as it is curving beneath the tube).
Mines undated too on both machines I’ve got. Maybe the guys that sold yours got lax on removing the sticker lol!
