Duplo 616 questions before purchase

[printox]

We have a Duplo 645 and want to get another unit since this one is one its last leg. Have a few questions if anyone can answer one of them.

1. Are paper jams common and how do you remove them?

2. Do these run better text weight (80lb text) then the bigger units (645)? It appears the rollers are closer together.

3. Why is this so slow in specs compared to the larger production machines like the 645?

645 has 4 motors for driving. 616 only has 1 so its 1 sheet from start to finish.
jams are tough as slitters are not removable like the 645.
Not sure about closer together but none of the units like lighter weight paper.
Look at the 618. Its small like the 616 but has great features like the bigger units. Not many used 618 machines out there though.

Can you even run 80lb text through these? I've never been able to get the 618 to run text weight paper without it causing major issues.

IE if I try to run 100lb Text it will technically do it but the static build up causes paper to build up on the cutter which sends little tiny slivers of paper everywhere and those slivers get inside unreachable areas and block sensors or jam the machine up so that the only way to fix it is to disassemble the machine and/or try to find and vacuum out those slivers.

Basically unusable for text weight paper IMO.

That helps and makes sense about the speed. 616 are under 10,000 and the 618 are around 40,000. Our 645 runs 100lb uncoated text very well but not coated 100lb text. Does it take a lot of effort to dismantle an area for paper jams on the smaller units like the 618?

The problem with the 615/616 is when you get a jam the slitters are not on a lift out module like the larger 645/646. THe new 618 gives you the ease of lifting out the modules.
If you get a jam we find it easier to gently work with small tweezers with a 45/90 bend. If its jammed good it does require some patience and skill. Sometimes the heads need to come out which requires all the shafts etc to come out. Few hours work.
Thats why i dont recomend light weight stock
