!
A high degree of precision control is required of the
scanner mechanism, and so extremely precise
installation and adjustment are carried out during the
manufacturing process.
Therefore, never disassemble any scanner parts
unless specifically instructed to do so in this section
of the manual.
!
When removing the scanner mechanism from the
housing to carry out disassembly, be sure to place the
scanner mechanism on top of the leveling tool before
disassembling it.
