skew adjustment 7r

wondering how to adjust the image skew. it is off about 1mm. i saw the adjustment in a wizard, but i dont know where the locking screws are. right now i cant remember where i saw the wizard either.

Thanks.

 

Are you sure that you have image skew, not paper skew in simplex? Because image skew is done by Writing Head adjustment with transparent jig.

 

paper is square, and the image on the paper isnt square on the sheet. the images dont back up front to back. it is consistent on all substrates. The wizard tells me to loosen the locknuts in the back but i dont know where they are.
