Everyone in this industry can register a job.
For that matter, technically next time you put a job on and say head 4 had to previously be adjusted... well then guess what head needs to be adjusted "back to zero" for the job to line up?
So you just go over to head 4 and line it up like you would if it was out of whack and Poof, you are back at ZERO and can go on printing all the rest of the days jobs.
Now, if you feel like that won't happen then this press operator you are talking about has more problems than you do and should probably do as you should and look for a new career.
Stop making mountains out of mole hills with the MHM zero'ing thing. It's simply not that complicated and just the time saved by not having to go around the entire press using a jig to snap frames in will be enough time to "zero" in that one job that some how the user screwed up on the FPU.
Which it could be argued that the same job would still take even longer on your press because the MHM's micros don't have to be locked down... so the time it takes to lock down your micros you could probably reregister back to "ZERO" on the next job and never miss a beat. Which means the time you waste going around with your pallet jig to set up all the jobs every day... well, it's just that... a waste!
MHM, lock and load!! You could have a monkey load and "register" a job on an MHM with about 2 mins of training. The same can't be said with your press Jig.

Actually Barnes is kinda right on this. If your MHM doesn't have the auto-zeroing electric driven micros, then you're stuck with pointers to re-zero your micros. Unless you have dial indicators or electronic read-out of position you'd be trying to re-zero the pointers by eye and would be lucky to get within .015" - .030" of actual centre, and what the point of having a FPU for jigging screens if you're messing with micro's before you start anyways, same goes for re-zeroing to marks or film on the platens, doing that is the exact thing we're trying to get rid of in the first place by jigging the film to the screen and screen to the machine.
A jig that goes in the place of, or better yet on the platen is a much better idea as then all screens are jigged to the same positional piece. Pins on the head only work if they never move or can be re-set in a fashion easier than what we already do to register screens with the micros.
It'll be at least 2 weeks before I can start making my own.
