Introduction
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.
Å@In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the
arrow indicates the direction of the electric signal.
Å@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 addition, the asterisk (*) as in "DRMD*" indicates
that the DRMD signal goes on when '0'.
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."

1.1 Features
1.1.1 Features
0009-2599
1. High-Speed, Compact Mono-Color Printer
The machine’s body is compact in design perfectly suited for installation on a desk, and yet it is a mono-color printer capable of turning out as many as
12.0 prints (A4) every minute.
2. Shorter Wait Time and Lower Power Consumption
The machine uses an on-demand fixing method, enabling a shorter wait time and lower power consumption when compared with machines that use a roller
fixing method.
