    Challenge cutter paper deflector?

    Ah thanks! It helped me figure it out. It literally just keeps the trim from getting pushed into the space between the blade and the frame of the cutter. Its supposed to travel down with the blade and back up with a spring. Mine is just stuck in the down position. I can bang it with a hammer...

    Challenge cutter paper deflector?

    I’ve been operating a challenge 305mc cutter for ten years, and I’ve never been able to figure out what the paper deflector does. It doesn’t move, it just sits there on the left side of the blade. I see there’s a little red knob under the table extension that you can loosen and tighten but that...

    Good replacement for Zipset

    I was out of the loop about Zipset/Tokyo Ink Manufacturing ceasing North America operations. I've been using Zipset No Skin series inks for the last 15 years in my shop and now I'm stuck looking for a good replacement. I run small duplicator presses with continuous dampening and these inks ran...

    Hydraulic vs. pneumatic hot stamping press

    I’m about to purchase a vertical foil stamping press for decorating book covers, and the overseas firm I am talking to offers two nearly identical models of press, the only difference being one is pneumatic and the other is hydraulic. They cost the same, offer the same printing pressure, etc. My...

    Ryobi 3302 intermittently skewed feeding

    Interesting! How do you run without them? Do you set the stationary side so that it is exactly touching the edge of the sheet when the oscillating side is fully "in"?

    Ryobi 3302 intermittently skewed feeding

    Yes thanks! I took a slow-mo video with my iPhone and realized that the problem was my spring placement. The paper was occasionally curling up on the edge that was coming in contact with the spring, rather than being pushed against the lay, causing it to skew away from the lay. I had that spring...

    Ryobi 3302 intermittently skewed feeding

    I've been working with this press for years. I recently replaced the lower feed roller with a new one, and it seems like ever since I have been having trouble getting it to feed straight. Seemingly at random (and approximately 10% of sheets on a given run) a sheet will feed skewed, with the...

    Pressure issue???

    Sorry to bump an ancient discussion, but I seem to having an identical problem to Jeremy, also on unit 2. The first sheet prints great, but every subsequent sheet is speckled, due to a slight loss of impression force. I have been staring at the cylinder linkages all day, and I can seem to find...

    Prochem California Wash?

    I usually use the Varn CA wash. This time my vendor (great western) sent me this Prochem stuff. It is very different. Its thicker and oily, and definitely not a quick drying solvent. It does have some advantages, it seems to clean better with much less volume of solvent used. It also has almost...

    Sheeted bible paper

    I've managed to get about 50 sample sheets from Twin River and it fed and ran surprisingly well.

    Sheeted bible paper

    Small family printing business owner here. I've been looking for a good source for cartons of sheets of "bible paper" (uncoated white offset papers in the 20-30 lb range) for years now. I get asked about this by clients all the time, and always have had to tell them that I don't know how to get...

    Perfect binder "twisted" spines

    This has me completely stumped. Books are coming out of my perfect binder with a spine that seems twisted. The covers are slightly puckered and won't lie flat against the book. If I slice one of the books into section on the guillotine, I can see that the spine is tighter against the book block...

    Bookletmaker Stitcher problems

    Running a Watkiss collator and Automatic Stitch Fold Trim booklet maker that uses M2000 type stitching heads. I am running a booklet that is 5 by 4 inches and has one off-center stitch. I can only get three booklets to run through the machine and get a staple. After that, the wire buckles and...

    Ghosting has me stumped

    If that were the case then cleaning the blanket wouldn't help, but it fixed the problem for another couple hundred sheets. Also it would seem that if the image were being picked up by the feed rollers, the repeats would run all the way down the sheet rather than twice above and twice below the...
