Used Duplo 645

[jasonlesher]

I'm taking over the small family business in January and looking at Cutter-Slitter-Creasers. I'm seeing a used Duplo 645 with an attractive price tag, but no idea how long they hold up. Its 10 years old with 4 million cuts/slits and 200,000 creases. Any thoughts or questions I should ask? Or just forget it?

Search the forum as this topic comes up regularly. Cutting to the chase, the 645 is a very old model, approaching 20 years old I believe. We don't have an SCC but did look at them a couple of years ago and concluded the 618 is the winner, since it is fast and the tools are removable. So if we ever get one, it would be the 618.

Buying a 15 year old SCC is akin to buying a 10 year old digital press. Generally it's been ditched for something more modern because it's become tired/expensive to maintain/inconsistent in output quality/reliability/no longer commercially viable. Personally I wouldn't touch it, as it's likely to become a bottomless money pit and even then, there's no guarantees it will ever be a reliable asset that will make you money, instead likely to introduce wastage and reprint costs. Buy once, cry once, and get a 618 (if you really need an SCC, that is), not a boat anchor.

Duplo 615, 645 are discontinued. The major replaceable items you cant get. The cutter unit and motor. Rollers?? Id stand clear unless it is really cheap.

Please, I have a problem with knife No. 4. Trims 2mm less than others. The work is set up for the correct one. It is supposed to cut 9x5, but for knife No. 4 it trims 9x4.8.

Not sure I am following you. I have a 645 and it only has one knife. It does have 6 slitters. Is that what you are talking about. I have not had to manually go in and adjust any of the slitters sensor breaks but I have done that in the perforator module. The metal piece that breaks the sensor path can be adjusted so that it homes correctly. Of course you could always just you measure to account for that 2mm if you can figure out which one will be using #4.

Please how and where do I enter the service menu for calibration?
There it should be possible to adjust the width of the cut paper.

Can you cheat and fudge the numbers? You technically have to take something from one of the sides of the cards and add it to the card whether it's the gutter side or the end. I'm not sure what's in the service mode

I just took a look at the slitters. It appears that it is possible to adjust the metal plate that interrupts the homing sensor signal.

Please, motor for elevator is out - K.O.. I need buy new motor or Watt and rotary motor. Thanks

Are you sure it's the motor? Never replaced one before. Most of those motors have gear reduction boxes attached to them. Maybe its in the gear box.

Yes, unfortunately yes. A new one is already ordered (quite expensive ). What bothers me a lot is that it's impossible to find out what its RPM and Watts are anywhere, it would be much cheaper then.

I've run into this on another piece of equipment with the same result. Sometimes motors are custom made for OEM's. That's why you don't see anything on the web related to the part # on the label.
