Plate not reaching register pins

[Kaoticor]

Having a problem with our Magnus VLF with continuous feed not reaching the pins on the leading edge when it is getting loaded on to the drum. The plate picks just fine, but when it is being moved on to the drum, I can see that it is not going in to the clamps all the way. We keep getting the error that the plate has not reached the register pins. Looks like the suction is fine and the cups are not dirty and have enough suction. Anyone experienced this problem before? Thanks in advance,

K

There are quite a few things that can cause this - plate stack not loaded properly in the cassette or not positioned correctly against the plate stops, wrong machine settings, mechanical interference in the loadtable, loadtable motor losing steps, worn out load table rails and peeling UHMW tape, dirty contacts on the registration block with 6 contacts on the drum side, wrong LEC gap etc....
There are quite a few different styles, options and changes for this machine and it won't be easy to fix.
Is the problem intermittent? Plate size dependent?

Thanks for the feedback nemo. We went around in circles for a bit, but yes, it was plate size dependent. It ended up being a warp in the plates. Was wierd because the bad plates were not the entire box, looks like just a stack right in the middle of the order. It wasn't the whole box of plates, which made it difficult to troubleshoot. Since only some of the box was affected, they ended up getting spread out all through the cassettes, so it made it look like an intermitent problem rather than something that was tied to the plates. Lost time in troubleshooting because we stayed ahead on our plate loading! Thanks again,
