4.4 Disassembly of Scanner Unit

4.4.1 Scanner Housing

C A U T I O N
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 an
environment that minimizes intrusion of dust and dirt.
Disassembly and assembly on a clean bench is ideal.
Perform disassembly and assembly with care not to damage the
document table (glass). In addition, never forget that a very
troublesome cleaning is required if dirt sticks to the inside of
the document table.
Take care in handling the Housing Lower, remembering that
grease is applied to the CR guide area of the Housing Lower.
Do not touch any parts with a greasy hand or part.
(Fig. 4-48)
Take care not to soil or scratch the Encoder Scale or the lens of
the ICS Unit.
