Explanation of SymbolsThe following symbols are used throughout this Service Manual.

Symbols Explanation Symbols Explanation

Check. Remove the claw.

Check visually. Insert the claw.

Check the noise. Use the bundled part.

Disconnect the connector. Push the part.

Connect the connector. Plug the power cable.

Remove the cable/wire from the cable guide or wire saddle.

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 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

Laser SafetyLaser beam radiation may pose a danger to the human body. A laser scanner mounted on the machine is sealed with the protection housing and external cover to prevent the laser beam from leaking to the outside. The laser beam never leaks out of the scanner as far as users operate the machine normally.The following warnings are given to comply with Safety Standard (EN60950-1).

Sicherheit des LasersLaserstrahlen knnen fr den menschlichen Krper gefhrlich sein. Aus diesem Grund ist das optische Lasersystem mit einem Schutzgehuse und einer Auenabdeckungdicht verschlossen und hat eine Struktur, die keine Laserstrahlen nach auen dringen lsst. Unter der Voraussetzung, dass der Benutzer dieses Gert normalbedient, ist ein Austritt von Laserstrahlen daher ausgeschlossen.

1. As a general rule, do not use extension cords. Using an extension cord may result in a fire or electrical shock. If an extension cord must be used, however, use one for local rated voltage and over, untie the cord binding, and insert the power plug completely into the extension cord outlet to ensure a firm connection between the power cord and the extension cord.

2. The socket-outlet shall be installed near the equipment and shall be easily accessible.

Safety of Toner

About TonerThe machine's toner is a non-toxic material made of plastic, iron, and small amounts of dye.

Do not throw toner into fire. It may cause explosion.

Toner on Clothing or Skin If your clothing or skin has come into contact with toner, wipe it off with tissue; then, wash it

off with water. Do not use warm water, which will cause the toner to jell and fuse permanently with the

fibers of the cloth. Tonner is easy to react with plastic material, avoid contact with plastic.

Notes When Handling the Lithium and Ni-MH Batteries

RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE.

DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

The following warnings are given to comply with Safety Principles (EN60950).

Wenn mit dem falschen Typ ausgewechselt, besteht Explosionsgefahr.

Gebrauchte Batterien gem der Anleitung beseitigen.

Notes Before it Works Serving

At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.

Analog Control Performed by the CISThe flow of analog image processing performed by the contact image sensor (CIS) is as follows:

a. The light reflected by the original is collected by the rod lens array.b. The light is received by the CMOS sensor array.c. The CMOS sensor array converts the received light to an electric signal and outputs it.

The CMOS sensor array consists of four channels (units).Each channel is provided with an output correction table to output an image signal after performing gain correction for the input brightness signal.

Enlargement/Reduction

Magnification Change in Vertical Scan DirectionIn the Book mode or when the ADF is usedIn the vertical scan direction, the image is read at 100%. Magnification is changed by processing data on the main controller PCB.

Magnification Change in Horizontal Scan DirectionIn the horizontal scan direction, magnification is changed as follows depending on the selected magnification rate:1) When magnification is reduced to 50-99%

a. In the Book modeData is processed on the main controller PCB with the original scan speed held at 61.5 mm/sec or 123 mm/sec.b. When the ADF is usedThe original feed speed is changed within the range of 61.5 mm/sec or 123 mm/sec to 246 mm/sec depending on the selected magnification rate. Data is not processed on the main controller PCB.

2) When magnification is increased to 100-200%The original scan speed (in the Book mode)/original feed speed (when the ADF is used) is changed within the range of 123 mm/sec to 61.5 mm/sec depending on theselected magnification rate. Data is not processed on the main controller PCB.

Technology > Original Exposure System > Controls > Detecting the Size of Originals


Detecting the Size of Originals

OverviewThe original size is identified by the combination of presence and absence of output levels of the reflection type sensors as summarized in the tables below.- Absence of paper: The light reflected from the reflection type sensor changes when the copyboard cover is open/close.

- Presence of paper: The light reflected from the reflection type sensor does not change when the copyboard cover is open/close.

This machine is provided with the following sensors. Locations of the sensors are shown below.- Vertical scan direction: Reflection type photo sensors (2 locations for AB; 1 location for Inch)- Horizontal scan direction: Reflection type photo sensors (2 locations for AB; 2 locations for Inch)
