Why is cannibalizing the new printers not an option?
If you can replace
2 good reasons...
1) There's not an unlimited supply of 'new' plotter mechanisms
But more importantly
2) These gears fail in storage anyway. I think it's from the stressed
caused by press-fitting them onto the motor spindle -- they crack
longtitudinally between the teeth. For example, my CGP115 was OK when I
packed it away. When I got it out again a year or so later, one of the
gears had failed. Now I think both are broken.
