Section 8 Printed Circuit Board Layouts and Parts Lists
The following P.C.B. pattern layout drawings and parts lists are provided for
service reference. Parts list includes only main parts or the parts difficult to
obtain in the field. Also the lists include the parts which should be replaced
with the exact same parts supplied by OTARI to maintain performance. Many
diodes, transistors, and ICs are well described in the schematics attached to
the machine, so to find out the correct parts number of the needed parts,
refer to the schematics.
