Paper Registration: Trailing Edge

No problem

The machine feeds most reliably long grain feed.

If your paper cutter is sometimes cutting with the grain and sometimes against the grain, it could produce different size stock due to paper buckle during the cut

Thanks for the response.  

Orginially that was what I was thinking in terms of getting single sided jobs corrected.  Unfortunatly it wouldn't fix the issue for double sided jobs.  In terms of registration on the LE and IB we are perfect, the paper just isn't.  Might have to ask our paper cutter to take his time.  

Thanks you for all your help, I have my questions answered!

I'm not trained on that hardware but I am familiar with the registration hardware on c60, v80, d95, and all office hardware

On those the reg sensor bar is physically loaded to only capture the IB/LE

The file generates the file size on the IBT and it waits to transfer to media. You can adjust the registration through your DFE but when bringing the product into spec we run test patterns that draw lines on the paper that bring it to lock in on the 10 mm mark ib to edge and ob to edge

When it runs duplex reg is now based on TL (which is the LE on side 2). Flipping the paper upside down and backwards would accomplish what you are looking for for side 1 prints.

When it comes to printing things like business cards there is almost always some DFE manipulation on side to side registration unless your product is really dialed in on whichever tray you are working from

Thank you for the reply.  

I figured that this was the case, but I wanted to make sure.  With the way the paper is being cut, we won't be able to eliminate all of the varience that happens within a pallet of paper. 

That brings me to my next question: can you register the paper off of the outboard side instead of the inboard?

Sorry no

You could make a custom stock for the variance in size. Save a couple templates to match the cut.

This is assuming you bulk cut for a ream and each ream is exactly the same. With different reams having the variance between them

Hello, 

New to the community and need a little help.  Machine is running great in terms of production.  We're anywhere from 15,000-18,000 sheets a day out of it!  My understanding of these machines is that when an image is layed on to paper, it uses the inboard and leading edge as the registration?  Because we cut our own paper, the sizing can vary around an 1/8 in on a daily basis. This presents a problem because when we are cutting and assembling our paper we use the trailing edge as the registration point, so it needs to be the same every time.  Since the paper has a varience in size, the trailing edge margin changes and messes up our assembly process.  Is there a way that I could get the printer to register off of the trailing edge so it has the same margin every single time?  If any one needs pictures to see what I am talking about, I would be happy to upload some.  

Thank you.
