Manual Structure
This manual is the Service Manual Vol.1 of the Color Video Printer UP-21MD.
This manual contains the service information, electrical alignment and mechanical
alignment, sensor arrangement and functional description, circuit operation
description and troubleshooting.
In addition to this Service Manual Vol.1, the following manual is provided.
* Service Manual Vol.2
Part No.: 9-955-307-21 (for J, UC, CE)
Contains the semiconductor pin assignment, spare parts, block diagrams,
schematic diagrams and board layouts.
* Instruction Manual
Part No.: 3-206-154-11
This manual describes the information required for the actual management and
operation of this unit.
* “Semiconductor Pin Assignments” CD-ROM (Available on request)
This “Semiconductor Pin Assignments” CD-ROM allows you to search for
semiconductors used in B&P Company equipment.
Semiconductors that cannot be searched for on this CD-ROM are listed in the
service manual for the corresponding unit. The service manual contains a com-
plete list of all semiconductors and their ID Nos., and thus should be used together
with the CD-ROM.
