The A128 copier has the same troubleshooting procedure as that of the
A110/A111 copier. However, some connector numbers are different from
those of the A110/A111 copier. Refer to the connector number cross
reference table on page 27 to 29 of the A128 copier service manual.
NOTE: The A128 copier has the same voltage scanner motor drive signals
as the A111 copier. Check the voltage on page 6-29 to 33 according
to the procedure for the A111 copier.
