Epson B813102 Using Manual page 4

Note:
If you can't replace
the shipping
screws, the TPU's
lamp assembly may
not be in its home
position. If this is the
case, reattach the
TPU to the scanner,
close the TPU, and
turn on the scanner.
The lamp assembly
returns to its home
position. Turn off the
scanner, remove the
TPU, and insert the
screws.
3 Install the screws in the storage holes labeled STOCK
between the shipping holes, as shown below.
Before transporting the scanner, turn it off, remove the TPU,
and replace the shipping screws in the outer shipping holes
labeled CLAMP. The transportation lock screw on the scanner
must also be locked before transporting the scanner (see the
scanner's Setup Guide).
