HP Officejet Pro 8630; copies and scans printing off center

First let us assume it is a human error (I have one of these).

Take a sheet of 8.5x11 inch paper and make a heavy line 1 inch in on all sides.
Now put it in the scanner feeder and squeeze together the guides so they almost touch the paper but do not bind.
Now scan and check.

Alternate test:  Put the paper above square on the platen bed (no feeder) scan and test.

See if either work.

neither one changes the off center scan/copy,  internal head reader is off center and I am trying to find out how to re-center it.  the scanner/copier worked fine until I had a paper jam and now it prints copies and scans off center.    I tried to find a service manual for this machine but could not find one.

So if Scanner or on-Platen scan is off center, the mechanism on top is not centering or worn.

Open the lid behind the feeder (top left of the printer), look inside for bits of paper, and (remember that there are delicate rollers in there) clean gently with a soft cloth or paper towel.

If you are good at it, and most careful, use a vacuum cleaner to suck up bits and dust. Pay attention to the path areas.

The printer may need service.

try to reset it, as shown here :

@Pat Taylor - Did you get the printer serviced?

I called and they want more money to service it than I paid for the printer😕

did you reset the printer yet?   result?
