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.

　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.

　The expression "turn on the power" means flipping on the power switch, closing the front door, and closing thedelivery 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 toindicate "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, theoperations of the microprocessors used in the machines are not discussed: they are explained in terms of fromsensors 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 otherpurposes, 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 relevantService Information bulletins and be able to identify and isolate faults in the machine."

002RTN transmission

condition (1)

Use it to set RTN signal transmission conditions.

Raise these parameters for more lenient conditions if

errors occur frequently at time of reception because

of transmission of the RTN signal.

Memo:

Any of the following error codes may be indicated at

time of reception because of RTN signal

transmission

##104, ##107, ##114, ##201

RTN signal transmission condition (1) affects the

ratio of error lines to the total number of lines per

single page of received images.

RTN signal transmission condition (2) affects the

standard value (*2) of burst errors (*1).

RTN signal condition (3) affects the number of errors

not reaching the standard value of burst errors.

*1: transmission error occurring cover several lines.

*2: for instance, if '15' is set, a single burst error will

represent an error occurring continuously cover 15

lines.

If any of these lines is detected while an image signal

is being received, the RTN signal will be transmitted

after receiving the protocol signal of the transmitting

party. Higher parameters
