This Service Manual provides basic facts and figures needed to service the Stapler
Sorter-L1/MS-C1 in the field and consists of the following:
Chapter 1
"General Descriptions" shows features, specifications, and names of
external parts and how to operate the sorter.
Chapter 2
"Operations and Timing" discusses the sorter's mechanical and
electrical systems by function and various timing of operation.
Chapter 3
"Mechanical System" shows how to disassemble, assemble, and
adjust the sorter.
Chapter 4
"Maintenance and Inspection" gives lists of periodically replaced parts
and consumables/ durables and a scheduled servicing chart.
Chapter 5
"Troubleshooting" shows how to troubleshoot possible faults and gives
electrical parts arrangement diagrams, LED/check pin diagrams by
PCB, and self diagnosis tables.
In addition to the above chapters, this Service Manual contains an Appendix
consisting of a general timing chart, a signals/abbreviations list, communications signals
list, a General circuit diagram controller circuit diagrams.
For installation, see the Installation Procedure that comes with the mounting kit for the
Stapler Sorter-L1 and MS-C1. (Hereafter, the Stapler Sorter-L1 will be referred to as the
"stapler sorter" and the MS-C1, "non-staple sorter.")

The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and
the relationship between electrical and mechanical systems with reference to the
timing of operation.
In the diagrams,
represents the path of mechanical driveÑwhere a signal
name accompanies the symbol
, the arrow indicates the direction of the
electric signal.
The expression "turn on the power" means flipping on the power switch, closing
the front door, and closing the delivery unit door, which results in supplying the
machine with power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is
"High," while '0' is used to indicate "Low." (The voltage value, however, differs from
circuit to circuit.)
In practically all cases, the internal mechanisms of a microprocessor cannot be
checked in the field. Therefore, the operations of the microprocessors used in the
machines are not discussed: they are explained in terms of from sensors to the
input of the DC controller PCB and from the output of the DC controller PCB to the
loads.
The descriptions in this Service Manual are subject to change without notice for
product improvement or other purposes, and major changes will be communicated in the
form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this
Service Manual and all relevant Service Information bulletins and be able to identify and
isolate faults in the machine.
