No much stronger than the DF 1200 Larger too,

they need to be flat to flat. You might gently pry apart heads and push blade over. How ever if they are worn the blades just barely overlap and it will do it again.

What we found was if you replace the cutting unit the motor was worn too. Few months later motor needed replacement so Duplo sells it as a unit now. Yes pricy. Is it worth it to remove everything just to send the blade to the grinder? We tried it on the 645 cutter and it didnt last long. Maybe...

Yes old guy here. I found the same issue years ago. Older guy told me the weight of the clamp and your tightening is magnified so getting it loose to raise takes more of a effort.

If you guide leans in and binds paper try turning it around so it angles out. Or just bent the guide. I agree they cant bind or you get feeding issues.

So a feeder into the SCC then booklet maker with trimmer? Why not let the trimmer do a face trim? Or if the covers are oversized the SCC can trim all 4 sides but leave the head/tail a slight bigger and trim on the trimmer as a complete booklet.

Refurbished is usually completely torn down cleaned and rebuilt. Worn parts are usually replaced if needed. Hohner heads last much longer than the old Interlake heads.

On the same disk there is the operating software and the drivers. So install software exit out then install drivers. Power off everything plug in cable then turn everything back on.

Still have feeding issues with your 646??

Using black buttons cycle cutter watching gauge. On the way up look for 500/600psi. If not down below on the manifold there is a adjusting valve upper right area. Turn clockwise for more pressure. Checking cycle watch gauge just before knife hits table gauge should be 1500# then might jump to...

it is either on a name plate on the right side back or stamped into the top of the table by the right cut button

C+P will only work on the display board as they built it for Procut. I think its a valve issue. Dirty or out of Wack. What's the SN of the machine??

If its hunting I would lube up the guides under the table and also the leadscrew. When its all lubed good then slightly adjust the back guage gibbs to sort of drag. But you dont want to strain the motor if you go too tight.

Im not 100% but I think the clamp and knife kind of follow each other up on the return cycle knife hitting home first. Going Down the clamp should be hitting the table build up pressure and switch over to bring the blade down. Whats the SN for the procut. Too bad they had such a good cutter back...

Duplo still sells them as a single part. You need top and bottom blade in each head.

Not to put people out of their job but from what I see in shops that do say business cards is someone stands at the cutter for hours cutting. With this type of machines, you set the initial program load the sheets and walk away. Go over to the cutter and continue with another job. Come back when...

Swapping rollers? Keep them clean with mild stuff like Simple green. Slitters can be changed as a whole head assy or rebuilt with just new blades. New heads are more $$ but rebuilding takes more labor$$. Not a huge savings. Yes the cutter and its motor get replaced as a whole unit. They wear out...

Few things on these machines. First series to the next series. 615-616 645-646-648 745-746 618 is a mix of old and new ideas. Sticking with the new stuff. 616 machine you cant take out the modules if you get a jam. Pain to clear. Where as the 645/745 series and above you can. Makes it...

Yes your image might have too many slits. You only have 6 slitter blades and 20/25 cuts per sheet. So some folks need more slitters because they are cutting out gutters rather than just a slit between the sheets.
