Duplo DBM 350

It must be my week for breakdowns!

The booklet maker can run fine for hours on end with no problem but then randomly start failing to eject the booklet from the stitching area, the staple are well formed and not deformed - its almost like something is sticking and keeping hold of the booklet but we cant see what - I have checked the clinchers and they all seem free.

Any suggestions before it drives us insane

Thanks
Chris

Welcome to insanity. Look at the stitch head stopper fingers. Is it broken? Or is it sluggish when dropping out of the way? If it gets warm and sluggish it will delay the book movement and cause a false jam.

We actually thought it was the stopper that was the problem, but we have replaced the selinoid that controls it and ensured its well oiled and to the best of our experiance its certainly free. It definatly is weather/usage dependant as the longer/harder its used the more likely it is to play up. we bookleted around 700 books this morning with no problems and now we cant get 2 in a row out of it.
