Important note regarding LD unit spacer replacement
The following shows the P/N (location) and color for the four spacers attached to the
bottom of the LD unit.
! Whenever replacing the LD unit, please be sure and remove the spacers from the old
unit and attach them to the same positions on the new unit.
! However, if any of the spacers are misplaced or the positions/quantities of spacers
becomes unclear at unit replacement, follow the procedure on the next page to realign
the LD unit and eliminate variations in image density.
