The NP-1530 is designed to accommodate the following for fully automated copy work:
1. Stapler Sorter-B1
2. MS-Al
3. ADF-Al
4. Control Card V
A separate service manual is made available for the Stapler
MS-AI, ADF-AI, and

CHAPTER 3 OPERATIONS AND TIMING explains how the NP-1530's electrical and
mechanical systems are related to each other with respect to functions and timing of
operations.
In CHAPTER 4 MECHANICAL SYSTEM, the NP-1530's mechanical system is discussed as
to its operation, disassembly, reassembly, and adjustment.
CHAPTER 5 INSTALLATION gives step-by-step instructions for installing the NP-1530
together with checks to make for each step.
CHAPTER 6 MAINTENANCE AND SERVICING contains tables of replacement parts and
consumables.
In addition to the above chapters, this SERVICE MANUAL contains a set of appendixes
consisting of a general timing chart and general circuit diagrams.
A separate document entitled SERVICE HANDBOOK is also available for troubleshooting
problems in the NP-1530.
