 Once the Scanner Housing is removed, there is a possibility that
dust and dirt may enter the inside of the scanner body. Perform
disassembly and assembly of the Scanner Unit in a clean room
or on a clean bench to keep away from dust and dirt.
 Perform disassembly and assembly with care not to damage the
document table (glass). It may require considerable time to
clean if dirt sticks to the inside of the document table.
 Take care in handling the Lower Housing. Because grease is
applied to the CR guide area of the Lower Housing, do not
touch any parts with a greasy hand or part.
 Take care not to contaminate or scratch the Encoder Scale or
the lens of the CIS Unit.

other reason, the scanner origin can be shifted from the correct
position; therefore, adjust the origin location after re-installation.
