NEC LC-810 Support Document page 23

Comprehensive
LC-800 Series
Problem: Half the page is out of focus.
Solution: Move the metal clips on the head assembly.
Find the head assembly with the previous instructions.
About half inch from the white wheels towards the outside of the printer, you will see a metal clip
(one on each side). The largest portion of the metal clip should be pointing towards the rear corners
of the printer. The left one to the left corner and the right one to the right corner.
Reason: The lens is mounted on two posts with springs behind it. Two metal clips secure the lens to the posts.
The lens can move up and down by pushing it up in the middle. Both sides of the lens needs to rest
evenly on the clips or the lens will be tilted causing the image to be placed on the PC Drum unevenly.
