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, in printing the oscillating roller squeals badly. Just started doing this today. Any thoughts? Thanks.

Roller issues, squeaky sound on No.4
Revised. I’ve recently refurbished a No. 4. When the roller carriage is in contact with the ink drum (hence the form roller clutch is engaged), there’s an awful squeaking sound. The front rider roller does roll, and the oscillating roller seems sort of sluggish. It’s difficult to gauge where the sound is coming from, but […]
MoreSP25 ink drum “bouncing”

MoreInstalling New Rollers — Clutch Pin Issue
While installing new rollers on the #4, I ran into an issue where the threaded pin (MR-109) won’t pass through the new clutch pin (MR-110) once in the roller. Separately, all the parts fit together just fine. Once on the roller core, the threaded pin will pass through the holes in the clutch block (MR-108), […]

Removed carriage to safeguard for moving. Now putting it back onto the bed. Forgot to mark the gear for proper line up, but I’ve done this before a couple of times, resolved that issue by trial and error. The main problem, and I don’t recall how I resolved it in the past: the nylon wheel […]

MoreSP-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. I cannot see any obstruction. Any help to a diagnosis appreciated.
MoreUniversal 1 automatic return tape replacement
Does anyone have experience replacing the tapes on an automatic return tower? One of ours is a bit frayed. What is a reasonable replacement tape? It looks like pretty standard flat twill tape but I’m no expert on materials like that. Thanks for any advice.
