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 refer-
ence to the timing of operation.In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates thedirection 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 insupplying 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, how-ever, 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 microprocessorsused 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 theDC 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 com-municated 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 beable to identify and isolate faults in the machine."

Chapter 3 Error Code
3.1 Overview
3.1.1 Overview0015-7054
The CPU of the machine's ADF controller PCB is equipped with a function to monitor the state of the machine, flashing the Original Placement indicator when itfinds a fault in the course of a check it runs as programmed. The machine communicates the presence of a fault to its host machine in the form of a code, which isany of the following 3 types; check the Original Placement indicator to find out the nature of a fault:
T-3-1
In addition, you may also use the host machine's service mode for a specific code for an alarm or jam; an error, on the other hand, will be indicated on the hostmachine's control panel in the form of an error code:
F-3-1

*1: Although it used to be considered as an error, as a remedy, consider it as a jam during reading. In case that the error occurs once again during the lock initialization at the time of the jam recovery, consider it as an error. In case that the lock initialization is executed normally at the time of the jam recover, the job can be continued.
Although driving the unlock motor, the level of the unlock HP sensor is not changed within the specified time.
