SP-15 Squeal
Got a bad squeal on the SP-15. Can’t figure out where the noise is coming from. Suspect that the back roller core is defective and the bearer is not holding it correctly. I think we need a new roller/core. Anyway,
SP-15 Trip issue
A student emailed me last night (I got the email this morning) that one of our SP-15s had stopped working in trip. The cylinder hits part of the trip mechanism and will not move. The cylinder moves fine in print.
Uni III Draw Sheets and Packing?
I wrote to NA Graphics earlier today to order some Uni III packing, but have not heard anything. We need something right away, and I’m wondering if anyone can recommend paper that we can use for packing under the tympan,
Uni 3 Roller Bracket
I’m not sure of the actual part name. See photo. It’s a bracket that goes on the bar that raises or lowers the rollers. I’m wondering if it should be loose or fixed? I thought there was a screw holding
Universal III Tympan Issues
We have successfully used mylar/acetate tympan on our SP-15s for years, but when we tried one on the Uni III, it keeps slipping. There could be multiple causes: 1. The mechanism for holding the tympan on the Uni II is
Universal III Roller Height

Universal III-Rag stuck in gear
While cleaning our new Uni III, one of my students managed to get a rag caught in the drive cylinder gear. They wisely cut the motor off and unplugged the machine, but our attempts to The chain is very tight;
Nyliners too big for SP-15?
Dave Seat discovered that both our SP-15 presses were missing the outer bolts that hold the outer nyliners in place. We ordered new from NA Graphics, along with nyliners, but the nyliners are too big; the neck is too long
Sp-15 Slowdown
One of our SP-15 presses at UAFS has an oscillating cylinder that is slowing way down shortly after being inked. It doesn’t seem to matter what kind of ink (ie, stiff or loose); it’s as though the ink is too
SP-15 Roller Bearing Block-clean?
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
SP-15 Disassembly?
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
