It actually looks a bit bent... dang..Originally Posted by Kiran Otter
I wonder if it's bent a bit, which moves the carriage close to the page about a foot to the left of far right.
now oddly, if I move the carriage by hand with the printer off, the area on the right, where the print is good, it's harder to move, you can feel the friction of 'something' but where the issue is, the carriage moves easier by hand and I feel no friction. Maybe the friction is a good thing, it's the channel touching the rear bearing and where it's easy to move, the bearing isn't touching the carriage is dropping lower.
Egads, the more I think about it the more this makes sense......
bummer, I can't even find that part listed
HP parts for Q6721A DesignJet z3200 44-in postscript photo printer
Any idea what this part is even formally called?

I think I know what your talking about......
The "support rail"? The tubes "ride" in it.
Yeah, I don't see that as an orderable part.
yes, that's the part.
Man not order-able eh? OK... then I will have to be creative then if that turns out to be the culprit!
You can try a couple other machines' manuals... I think it would be the same on a Z2100. Maybe a few others.
Or try to bend it straight.
Yes the straighten it thing will be first shot....
I'm trying to imagine here... since the carriage would pivot on the carriage rod, if the channel was lower it would pop the front of the carriage higher right? Like a teeter totter?
That part is just for the tubes to ride in.. it doesn't affect the carriage height. I suppose it could be bent out of shape so much that it's rubbing against the carriage somehow.. or installed incorrectly and causing interference.
The chassis where the carriage rides in the rear would be very difficult to damage, I think.
Also, there should be some play in the carriage; you can tip it up and down, or back and forwards as it pivots on the carriage rail. If it feels tight somewhere along the carriage axis.. I would expect either there's some kind of obstruction or maybe the bushings in the carriage are damaged, or inserted upside down maybe..? I don't remember on that carriage of the bushings can be removed and put in upside down like on the 500/800.

oh ok, so that channel would only affect if it's pressing when it shouldn't...
Dang...
I'll check the play in the carriage, that's something at least to check, thanks!
