Hi all, I’m the new caretaker of an SP 20 (serial 23442). I’ve been investigating a carriage jam issue and have found that the trip assembly on the non-operator side of the carriage (X-21755) is sitting much lower than on the operator side. Because of this, the rogue trip arm has been scraping against the […]

SP15 issue – uneven inking along length of bed
Not sure why I always run into issues when on deadlines… Having an issue where I get an impression but there just isn’t any ink on the form and would love to hear any thoughts on what the problem/solution might be. The uneven inking is happening for the length of the press bed. Was printing […]
MoreSpare SP20 parts?
I found these two pieces in a small box of miscellaneous odds and ends. Does anyone happen to know if they are for the SP20, paper guides perhaps? Thanks.
MoreSp-15, foot pedal on paper gripper
My Vandercook sp-15 has developed a weird quirk with the connection between the paper grippers and the foot pedal used to activate the grippers. When I step on the pedal, I have to press down harder that I used to in order to get the grippers to raise, and there is a loud metal kind […]
MoreSP-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, in printing the oscillating roller squeals badly. Just started doing this today. Any thoughts? Thanks.
MoreSP25 ink drum “bouncing”
The ink drum on my SP25 has started bouncing up and down at one end as soon as any slight pressure is applied, like when I lower the form rollers or when I wipe off the ink while the drum is turning. I can’t see any visible irregularities in the chain links or any of […]

MoreSP-15 carriage reassembly problem
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.
MoreSP20 Pitted Press Bed
Hi! I teach at a university that has a Vandercock SP20. I am looking for advice on how (if anyway possible) to alleviate uneven inking due to small pits in a press bed. We have a thin sheet of metal over the press bed to create the proper printing height, but we are still having […]

MoreSP15 Ink Drum uneven
Paul – That SP15 I sold to your friends at Old Dominion last year is having a problem with uneven inking = uneven pressure from the main ink drum. My guess is that, since it is spring-loaded, that either the spring has failed/is failing or that there is a build-up of ink and solvent coming […]
