d. Exposure unit home position search
If the exposure unit is not at the home position
when the main switch is turned ON or when the
START PRINT button is pressed, the home
position is searched for in the following manner:
(1) When the exposure unit is on the paper exit side
with respect to the home position
When the exposure unit is at PS7 (ADF brake)
(PS7 is ON), it moves forward at a low speed.
And it moves until PS5 (scanner HP) turns ON
and OFF again, then stops. It moves backward
until PS5 turns ON again.
When the exposure unit is between PS7 and PS5,
it moves backward until PS7 turns ON before
moving forward as mentioned above.
(2) When the exposure unit is on the paper feed side
When the exposure unit is at PS5 (PS5 is ON), it
moves forward at a low speed until PS5 turns
OFF before moving as discussed in (1) above.
When the exposure unit is located on the paper
feed side with respect to PS5, it moves backward
then stops for a short while after PS5 turns ON.
Then it moves forward and performs operations
as described in (1) above.
e. Read with shading correction
For 7075
After home position search, when L1 (exposure
lamp) is turned ON, the exposure unit moves
toward the paper exit side, thus reading the light
reflected by the white reference plate installed
underneath the glass stopper plate and
performing white correction. Then, L1 is turned
OFF for black correction, returning to the home
position. Shading correction is performed at 400
dpi and 600dpi.
