Phaser 850DP Not Striaght, out of alignmet?

[gorlinj]

I have a phaser 850DP that recently broke down. It seems that one of the paper feed sensors (one of the plastic things) broke so I took the part from an 840 and it is working great. Also, the paper feeder thing right above the paper tray broke off. It was the thing with white rollers and a strip of metal across. I also took the replacement part from my spare 840. Now everything prints just fine except that the image is misaligned. On a printout, holding it in portrait mode, the left section is higher on the page than the right section. For example, on an image, there is progressively more white blank space as you move from left to right on the top. It’s like the image got tilted somehow. Surprisingly, when I print from manual feed, there is no problem. Does anyone have any ideas?
Thanks

1)Check to make sure you got that pick guide asm in right. (the black plastic piece with the metal bar across the front.)

2)Check the deskew fingers on the front door. (There should be 5 lower and 5 upper. The lower are for the paper trays and the upper is for duplexing. If any are broken off it could cause skewing. The mpt bypasses the lower set.)

3)Pull out the paper tray and where the metal paper lift plate pivots on either side towards the back of the tray, see if the plastic pivots have broken. (one of the biggest causes of the pick guide asm breaking.)
