M602dn image skew

HP Recommended
Laserjet M602dn
Microsoft Windows 10 (64-bit)

We have a Laserjet M602dn that has recently started skewing all printed pages.  At first, we thought it may have been the new brand of 3rd party toner we were using, but moving the toner to our other printer does not cause the same issue.  I have checked all paper tray settings, and swapped out the tray from our other functional M602 with the same results.  I've replaced all pickup rollers with new.  I've also pulled out the duplex unit.  The skewing occurs from both tray 1 and tray 2, so I settled on swapping the registration assembly.

 

We have another (3rd) unit in the back that I use to pull parts occasionally, so I swapped out the registration assembly from that unit, again, with no effect.  I also swapped the fusing assembly from my parts unit.  Nothing.

 

So, to summarize:

Skewing from trays 1 & 2

Checked adjustments on paper tray

Replaced toner from known good printer

Replaced paper tray from known good printer

Removed duplex unit

Replaced all pick rollers with NEW

Replaced Registration assembly from parts unit

Replaced Fuser from parts unit

 

One final note...this printer has 1,627,863 prints on it.

 

Any ideas?

Honestly at that page count, walk away and replace it. Life rating on that engine is only 750K. You will exhaust more labour trying to get it working than it is worth. Just my opinion.

Thanks, repairatrooper.  I was afraid that was the answer.  I was hoping I was just missing something in my steps.
