I just bought a used Gallery Stretcher 60". I have stretched 3 of my personal ink jet printed canvasses and I think the machine does a good job. I, on the other hand can't seem to operate a stapler without damaging the canvas. I have tried various staplers and have decided I like the Fasco that came with the machine. However, I still get varying percentages of staples that blow through the canvas, don't staple at all, or I get it right. I have a regulator between the compressor and the stapler. If I get enough pressure to staple, it often blows through. If I turn the pressure down, it won't shoot. There doesn't seem to be an "in between". As I write this, wondering if I am applying too much physical pressure with each pull of the trigger, comes to mind. Maybe I should have tried that before creating this post. But does anyone know the answer or a better way?
 
You have not supplied much actual data here regarding the other staplers.
Staple guns can be adjusted regarding the force they exert on the staples. There is also the ram length of the machines that can be the cause of the staples digging into the wood strainers/stretchers.
The simplest solution is to back off of the surface of the target material so that they are not forced into the project. The nose of the staple gun is placed to touch the canvas or just off of it. a controlled method of doing this is also by filing off the ram's end or installing some sort of shim to keep the nose of the gun away from the canvas.

I can’t thank you enough for your response. Your last sentence is exactly what I have been thinking about trying. Thanks for giving me the go ahead.
 
This isn't uncommon as part of the dynamics is the density of the stretcher bar.
The kind of wood is important in that regard.
Basswood is relatively homogenous in density, whereas pine will vary a great deal with annular growth rings. Poplar will also vary in density, just not as radically as pine.
Finger-jointed pine is a particular challenge.
Another factor is the kind (brad point or chisel point) and leg length of the staples being used.
 
Is your canvas heavy cotton, or a synthetic blend?
 
You can grind down the driver (ram) length.
This will prevent the staples from going in too far.

When I got home last night from work, I filed the ram down. I can't tell you how much. That is now a company secret. By the way, I think we have the same first name, "Jerome". How about that? Not many people with that name.
