2. Description
Adjustment of SPF read position:
1.  Confirm that the MCU firmware fitted to the machine is version 5.32 (7.05).
2.  Place a black test chart on the OC glass, with the SPF open. Cover the slit glass with a
sky shot or similar black sheet. Do not put anything other than the black sheet on the
glass, and make sure that external light does not enter optical unit during the
procedure.
3.  Execute simulation 53-08. This makes the optical unit recognise the boundary between
the OC glass and the slit glass cover, and the SPF read position is automatically
stored.
Adjustment of SPF white correction pixel value
1.  Open SPF fully.
2.  Execute simulation 63-07. This allows the boundary position for the attachment of the
white correction sheet to be detected, and the CCD pixel position for white correction
is calculated based on that location.
3.  A value of between 35 and 172 indicates that the procedure has completed
successfully. If a different result is achieved, adjust the lens mounting position and
repeat.

4.  Close the SPF and execute simulation 53-09. The white level of the read white
correction sheet is displayed, and this value should be greater than 100. If it is not,
check the SPF white correction sheet for signs of contamination or deterioration.
MCU firmware version 5.32 has been added to production from October ’02.
