image registration problem in km 6501

[Albonline]

Question if you run a large size doc is the error consistant through the entire doc or does it vary within the doc?

documend size 12x18 or 13x19.
it vary within the same documend.

Maybe OP was referring to a bit of Magenta mis-registration , I tend to see this on heavy stock on small white text on a solid background. It might not show on 100gsm. If you look at the text with a loup you see the magenta knocked out by about 1/2 pixel and if you have 7 or 8 point font it looks like its filling-in with a red tinge. Especially around the 300-360mm area. Transfer belt/Fuser shock scenario.

Really its a Limitation of the machine.

toner exposure or/and 2nd transfer offset can help to this?

I would be looking at motor speed issues then.

Yeah helps to a point but cant really fix it altogether, Half a pixel knocked out in Magenta from fuser shock on heavy stock you are really only trying to hide it.

Like I say its a Limitation of the machine.
