We have had some trouble lately with roller height issues. On the SP-15, the user turns a knob to raise or lower the rollers. Sometimes it works, sometimes not. The bearing blocks have an allen bolt to hold the roller
Back in November, I posted about a screw broken off one of our SP-15s, (I think it’s called a shoulder screw), the screw that holds up the L bracket that holds the bearing blocks of the form rollers. The machine
One of our SP-15s has been experiencing inking issues; seems that we have to constantly adjust roller height and it gets out of whack very quickly. We discovered today two problems with the bracket that holds the roller bearing blocks
