Vevor manual guillotine not cutting through bottom layer, paper rips in the middle. Blade issue or alignment issue?
I bought a manual Vevor guillotine paper cutter, but it is not cutting through properly, especially the bottom layer of the stack.
The problem: when I cut a stack of paper, the upper sheets cut, but the lowest sheets often do not cut fully. Instead, the last layer tears or breaks in the middle, so I end up with the bottom sheet partly uncut and ripped.
I tried adjusting the cutting mat/strip position by loosening/tightening the bolts underneath and moving it closer to the blade. However, that mostly made the blade marks deeper in the rubber/plastic cutting strip, but it did not really fix the cutting problem.
So I am trying to understand what the likely cause is:
- Is the blade dull and should I try sharpening it?
- Is the blade position/alignment wrong?
- Is the cutting strip too low, too high, or incorrectly adjusted?
- Could the blade be touching more on one side than the other?
- Is this normal for cheaper manual guillotines, or should I return it?
I am worried that sharpening the blade might not help if the real issue is blade angle or alignment. Has anyone fixed this issue on a Vevor or similar stack cutter?
Any advice on what to check first would be appreciated.
