MP2000 - Skewed output

[sandmanmac]

I have this machine that I am out of ideas on.
It is skewing the output (prints or copies) by 3-5 mm every page, from all trays, including the bypass and it jams frequently in the fuser because of it.
I have checked /done all the usual things like registration bushings, paper feed components cleaning reg roller. I even swapped the PCU and PCR in case it was a due to uneven pressure or warped units
I finally discovered that if I set the printer to duplex and print the font pages, the duplexed side is perfectly straight, so to me, that eliminates a lot of areas that could cause the problem.
I thought I had solved it when I determined that the plastic vertical exit guide was warped: P/N B039 2585 (Item 7). but replacing it solved nothing. paper feed.pdf
If I stop the paper at the reg roller and manually turn it the paper feeds perfectly straight.
Any ideas about what else could possibly cause this? I know it's going to end up being something silly

Thanks

It seems you ruled out a lot of options. Maybe you can adjust the paper buckle with SP1-003. Just a thought...

Re: MP2000 - Skewed output

When you make a duplex copy with image on both sides, is one side straight and one side skew?

Re: MP2000 - Skewed output

*Did you replace or just checked physically the reg bushing? (try replacing the front and rear if you just checked)
*Have you tried checking the tray paper guide if they are straight and in position?
*Try the pressure and hot roller and see if they are in contact(check if there's same sort of space on one side btwn the 2 rollers) and if the two springs are having the right tension.

Thanks. That is worth a try. (Damn. I wish they weren't over an hour away )

The second side is perfectly straight every single time

Never replaced the bushings, but the pressure is good front and back, and since the copies are straight on second side when duplexing, to me that removes a lot of areas from the equation. It skews at the very top of the image - before it ever hits the fuser. Of course, tray guides are fine.

Re: MP2000 - Skewed output

This is probably stupid, but could it be extra humid paper? Going through the fuser once will take a lot of excess humidity out of the paper, which might account for the second side of duplexed prints looking OK.
Then again, it tends to make the paper wavy, which causes jams, and I'll just be going away now.

Your 'wandering' perspective is always welcome. Thanks for the laugh, Gene

Is it possible to post a sample of the prints?

Here you go. This is how it prints every page (sometimes worse)

in duplex mode this equipment model prints first verse and then print the front, so check the duplex tickets roll son the side cover,because probably there that is generating the skew.

As I said, the "duplexed" side is always straight. The sample shows what happens on NON-duplexed

Ok..

makes a stop test, when the leaf out of the tray, open the side door and checks if it is bent.

does this with the registration roller and with the fuser.

Re: MP2000 - Skewed output

interchange duplex unit Is one of the gears sticking,is the unit walking,tire gummed up

just a idea seen these babys cause issues try reseating it back in there..
