You folks are all correct. Its 2 different types of creasing. The normal crease bar is best the rotary tool unit does crease but uses rollers/wheels and may crack the print. If its just paper to crease you'll probably be ok.

Also the big red emergency stop will cause a cover error. Also maybe you had 2 errors and 1 still is causing it to fail.

Im curious about creasing the synthetic stock as a customer of mine tried on the Duplo and it doesnt crease well. Another person told me that type of stock doesnt crease well for any machine.

Maybe Colter Pederson in New Jersey

As others have said lube the backgage rails. Look in the table slot and oil the screw and along the left side smooth area. Go around to the left side and lube the other smooth side rail. then get that backagae to run back n forth over the lubed area. So many people forget to oil up these areas...

First Duplo 150 uses different cartridges. As for the 120 cartridges there is a issue with them but nobody owns up to it. I think the glue strip is too wide. Inside the head is 2 tiny fingers that flick the staple forward for the next cycle. If they slip on the glue it doesn't advance and you...

Most if not all will self bleed after a few cycles

Not sure what switch it is but either the one at the fold stopper fingers or when the folded booklet exits the machine. Its at the very end before going into the trimmer. Both switches have a lever type arm. Let us know.

I tried sending you a attachment with the disk contents on it. It came back permanent error. I dont think so on the dongle

David do you have the disk that came with the machine? Drivers are on it.

Never had a machine with 2 different heads. 500 always had hohner.. That area is the wire grip unit. When the internal guts of the head get pulled upwards during the cycle return that grip should close in most cases. If not above that area there is a Allen bolt head in the face plate. Crack it...

Remove the drive of the stitcher heads and run a few books without staples. Heads could be the reason your not completing a full cycle. If you still have a problem look inside the machine at the stitcher clutch unit. Big round thing. Spray some electronics cleaner on it to flush away any...

Are you in the states? Maybe Duplo or a dealer can get a chip for you

The 645 software wasnt hard to install. Im wondering if something is not quite right. TRy uninstalling the software including what drivers you might have and try again. TJ explains is like what should happen.

Just curious if you were able to find the counts. Duplo gives it an average lifespan of about 1 million sheets of 230 g paper since most people run heavier than that I usually go by 750,000 gives you a ballpark of when your cutter blade and/or slitter blades are getting towards the end of the...

If they sent you the software and you download it onto your computer when you get to the end of The install go back and install the drivers power the computer down and machine plug in the communication cable and then turn everything back on and it should communicate together. The software is...

No not the whole machine just the rollers. The rollers wear out from the far side to the operator side about 12 or 13 in depending on the width of the sheet. They are a soft roller they're made to help get rid of the static.

Still looking for DBM 120 parts? What are you looking for??

As others have mentioned about static tinsel. Make SURE it screwed onto bare metal. Also use that big side guide as it keeps all the front air inside the pile rather than letting it escape out the sides. Then that smaller guide with the slide part. Use that at the tail end to hold back the...

I had one customer that was told to rotate the rollers end for end. Gets a little more life from them. But is it worth it? Ya $200 each roller. Ive been finding 750-1 million sheets is about the max before everything is worn out. Spec at 1 million of 230gsm stock.
