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" m eans 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 fi eld. 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."

1.1.2.3 Safety of Toner
0018-4895
The machine's toner is a non-toxic material composed of plastic, iron, and small amounts of dye.
Do not put the toner into fire. It may explode.
Toner on the Skin or Clothes
1. If your skin or clothes came into contact with toner, wash with water at once.
2. Do not use warm or hot water, which will cause the toner to jell, permanently fusing it with the fibers of the clothes.
3. Do not bring toner into contact with vinyl material. They are likely to react with each other.
1.1.2.4 Point to Note about Fire
0018-4896
It is dangerous to throw lithium batteries and parts and components containing flammable substances, such as cartridges, etc., into fire. Such parts and components must be disposed of in accordance with local laws and regulations.
1.1.2.5 Point to Note about Battery Replacement
0018-4897
The batteries must be replaced correctly to avoid explosion. Do not replace any battery with one not indicated for the machine, i.e., use one of the same type or equivalent. Be sure to dispose of used batteries according to local laws and regulations.

Reading from the ADF
To avoid skew feeding, documents loaded on the document tray are retained in the horizontal direction by the slide guide. Then, the documents are separated one sheet each using differences in the coefficient of friction among the separation roller, documents, and separation guide. After that, the feeder roller feeds the document onto the reading glass, and the Contact sensor reads out image data of the document; then, the delivery roller delivers it to the delivery tray. The document feed motor drives the various rollers of the ADF.
