Vandercook No 4 gripper foot pedal problem
We have a No. 4 (S/N 8655) and have a problem with the foot pedal mechanism that interacts with the gripper trip assembly. The foot pedal is connected to the pivot mechanism on the non-operator side of the press by way of the bicycle chain on the outside of the press cabinet. I had the […]
MoreMore TagGripper Cam Question
Hello All, I own a Uni I. I’m trying to move my gripper cams to accommodate thicker papers and make the gripper pins open higher. I can’t get them to budge. I’ve removed all of the set screws, used penetrating oil, and lots of elbow grease. Any suggestions? This seems so simple, and I’m worried […]
MoreMore TagSP25 gripper problem
The SP25 at our school press (Virginia Commonwealth University – Bowe House Press) is experiencing difficulty when trying to raise the grippers. We tried oiling the exterior items that are attached – the X-22516 Gripper Shaft, but this did not help. This problem began in the past two weeks, before there was no indication of […]
MoreMore Tag15-21 Grippers rise unevenly
I got a call from our local art center that the grippers on the V15-21 rise unevenly with the ones closest to the handle lower than the others. They assembly has been taken apart and cleaned. Anyone have any idea what might be the problem or where I should start looking? Cross listing on the […]
MoreMore Tagautomatic gripper Uni I
I’m struggling with the automatic gripper on my Vandercook Universal I. I took it off, cleaned it, oiled it etc. but it still doesn’t jump back in position to open the grippers automatically. I wonder if the spring that sits between the side of the bed and the lever is not the cause. Can you […]

We have a No 4 (S/N 8655) that seems to take more effort lately to return the carriage to its resting position at the feed table. There is no problem leaving the feed table in trip or in print. Returning to the feed table seems fine in both trip and after printing an image until […]

MoreMore TagHelp! SP15 Grippers go up, but do not go down!
I changed the tympan paper three days ago, and since then my grippers are not functioning properly. When I press the gripper pedal the grippers go up, but when I release the pedal 3 out of 4 grippers remain up, and therefore are not gripping my paper at the feed board. Because I am printing […]
MoreMore TagTrouble with a 325 Trip Mechanism
I have a 325, serial #6086, and I’m having trouble with the trip mechanism. The pedal is completely unresponsive. It would seem that there was a problem with a spring or the spring link, but it seems to be at least connected fine. It’s not “snapping back” to create the tension one needs to raise […]
