The print co-op I belong to recently had the form rollers for our SP-15 recovered by Pamarco. After reinstallation, I adjusted both roller heights to achieve proper strike on the roller gauge. When the rear form roller is set to a proper height, the roller gear skips along the gear rack, barely making contact. When I lower the rear roller far enough for good meshing between the gear and rack, the roller sits at an unusably low level. What simple thing am I missing?
recovered roller diameter: 2.54″
form roller gear diameter: 2.62″
gear rack height: sits 3–6 points below the bearer. Shims in place.
the press bed is galley high with a bed plate.
impression is normal with a normal amount of packing for 0.040 undercut
Thanks in advance! Happy to supply pictures if needed.
