"origin point" or precise alignment for 2 sided printing

[netsol]

it's funny, i have been repairing this kind of equipment as long as it existed.
BUT in many ways i am still an amateur, i don't produce very much, (i get involved in too many other projects)

what is the procedure to set an accurate origin point, so, if i print double sided on the mutoh hybrid front and back are lined up perfectly?

when i am a little off i tend to blame it on the media detection of the machine (VJ-1617h)

So what if you're a little off, just like a vehicle, no one can see both sides at once.

this is the relative of a very important client.
she has been described as being much like : "attila the hun, sacking a village"

If you can align one side you should be able to do the other as well.

Even Attila, whether sacking or relaxing, can't see both sides at once. But, if you must know, here's how it's done.

1. Roll out sufficient media so the when the leading edge becomes the trailing edge, all media sensors will be satisfied.
2. Make a mark on the edge of the media at some geographical point on your printer. Like to the bottom of the black bar embedded in your printer's platen. Or whatever point that gets you off.
3. Print the banner
4. Roll out at least the same length of media as in step 1 and cut it off.
5. Measure the distance from your mark from step 2 to the leading edge of the banner and make an identical mark the same distance from the trailing edge of the banner. Or fold the banner in half lining up the leading and trailing edges and transfer the step 2 mark to the trailing edge.
6. Flip the banner end for end and load it upside down in your printer carefully lining up the step 5 mark with the same point as in step 2.
7. Print the banner.

If you did it right the leading and trailing edges should line up perfectly. The top to bottom registration is dependent on you reloading the media edge at exactly the same point on the platen.

When I'm doing 2-sided prints on the Epson, I mark on the media where the little holes in the media clips are then use push pin to poke holes in them to line up with the holes for the starting point for the back side. I usually have a bleed for the back side, and as long as we center the print it works out perfectly.

i really should have said, i was talking about my vj1617h
i am printing generally 48 x 50 sheets of coro (or sintra, or fome core ) 2 inches compensates for the 2 inches that stays in the machine

i have 6' conveyors with a guide so we go in straight
i have a spacer i lay in place if i am doing 36", 30" or 24" wide (easier than making the guides adjustable)

oops!
I did a sloppy job posting.
the Mutoh is a vj2617h HYBRID
trying to print on oro or fomecore
I go through a very involved alignment Procedure (adrian monk would be proud)
and still the Mutoh does a little f**king dance before it starts printing & my alignments go all to hell
