I had exactly the same problem with my OfficeJet 6110 as reported above (i.e. the scan head not knowing where the end-stop is). This is how to fix it (this method worked for me) 1) Lift up the scanner/copier hinged lid. Around the edge of the scan glass are 4 Torx screws. Undo all four screws. 2) Carefully prise the control panel faceplate off. The buttons underneath are on a single panel. Slide this to the left and lift off. 3) Jiggle the lid of the scanner to get it off the main body of the printer. 4) Locate the scan engine motor (top right corner) and remove the two motor retaining screws (one on the left of the motor, the other on the right). 5) Lift out the entire mechanism (rod, drive belt, scan head) and turn over. 6) Thoroughly clean all glass and mirrored areas of the scan head. Also clean the scan lamp on the top of the scan head. Clean the tray inside the scanner (where the scan head travels back and forth). Also clean the inside and outside of the scanner glass pane itself. 7) Refit all parts, using the technique described above, in reverse order. 8) Switch on printer. It should now work OK. Hope this helps, guys.
