Symbols Used

This documentation uses the following symbols to indicate special information:

Symbol Description

Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.

Indicates an item requiring care to avoid electric shocks.

Indicates an item requiring care to avoid combustion (fire).

Indicates an item prohibiting disassembly to avoid electric shocks or problems.

Introduction

Memo

REF.

Indicates an item requiring disconnection of the power plug from the electric outlet.

Indicates an item intended to provide notes assisting the understanding of the topic in question.

Indicates an item of reference assisting the understanding of the topic in question.

Provides a description of a service mode.

Provides a description of the nature of an error indication.

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 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 not ice 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."

1.1.1 Overview

Picture Quality Color Printer

High quality printing can be accomplished with the Canon Bubble Jet (BJ) method using the maximum 4800 dpi X

1200 dpi resolution.

Various media can be printed at high speed that is maximum 12 pages/minute in black and white or pages/minute in

color.

Convenient ASF

Up to 100 letter, leagl and A4 size sheets, 30 OHP films, and 10 envelops can be set in the ASF.

Copy Function

This machine can be used as a copier which achieves the recording resolu tion of 600 dpi X 600 dpi for black and

white copying or 1200 dpi X 1200 dpi for color copying.

Full Color & 256 Gradation Grayscale Scanner

Using MP Toolbox or MP Drivers (ScanGear and WIA driver), full color and 256-gradation grayscale images with

a quality of 25-9600 dpi can be read into a computer.

Photo Printing (MP370, MP390 only)

By connecting this machine to a digital camera with USB cable, photos can be printed out directly from the digital

camera (without using a computer). Moreover, photos can be printed out from Memory Card by inserting Memory Card into a card slot of the machine.

1. [ON/OFF] key Turns the machine ON and OFF. Before turning ON the machine, make sure the scan unit is closed. When tu rning

ON and OFF, keep the key pressed for at least one second.

2. [SCAN] key Switches the machine to scan mode. In scan mode, the machine scans a document to your computer according to the settings selected. This keyis used when the machine is connected to a computer.

3. [PHOTO PRINT] key Switches the machine to photo print mode.

4. [Photo Index Sheet] key Switches the machine to Photo Index Sheet mode.

5. [Menu] key Accesses the settings to customize operation of your machine.

6. [ (-)], [ (+)] keys Scroll through menu selections, and increase or decrease the number of copies or the image file number.

7. [Set] or [OK} key Selects or confirms settings. Also, press this key to recover to standby mode after correcting paper jams and other

errors that stop printing.

8. Numeric keys Enter numerical values such as the number of copies, as well as fax/telephone numbers and characters.

11. [Stop/Reset] key Cancels operations and returns the machine to standby mode.

12. [Tone] key Switches temporarily to tone dialing. Also changes the mode when entering characters.

13. [Redial/Pause] key Redials the last dialed number. Also enters pauses between or after numbers when dialing or registering numbers.

14. [Directory] key Use when dialing fax/telephone numbers registered in the directory.

15. [Additional Functions] key Switches the machine to user mode, in which you can customize the ink level warning, various fax settings,

maintenance, etc.

16. [FAX] key Switches the machine to fax mode.

17. [COPY] key Switches the machine to copy mode.

18. Alarm lamp Flashes when the machine is turned ON or OFF, when an error occurs, or when paper or ink has run out.

19. LCD (Liquid Crystal Display) Displays messages, menu selections, and the operation status.

* When unplugging the power cord, be sure to press [ON/OFF] first. When you press [ON/OFF], the print head is

protected by the cap to prevent the ink from drying. Turn the machine OFF with [ON/OFF]. When unplugging the power cord, be sure to unplug it after turning the machine OFF with [ON/OFF].

* When not using the machine for a long time, to prevent degradatio n of the print head , print or copy in both black

& white and in color, or perform print head cleaning, about once a month.

* Numerous nozzles are installed in the print head for high-precision printing. Just as the uncapped tip of a ballpoint

pen or marker becomes dry and unusable if not used for a long period of time, the print head nozzles become

blocked by dried ink. Periodically printing or cleaning the print head can prevent this blockage. * The power cannot be turned OFF with [ON/OFF] when the machine is operating. * Your machine performs a print head cleaning every time you plug in the machine. This ensures optimum print

quality but also consumes a small amount of ink during the cleaning process. * The machine cannot receive faxes when the power is turned OFF.
