1. FEATURES

1.1 Overview
This product is a G3 transreceiving facsimile based on the ITU-T recommendations. It can be used in telephone networks.
*: This mark indicates a new function.
Picture Quality Color Printer
High quality printing can be accomplished with the Canon Bubble Jet (BJ) method using the maximum 1440dpi × 720dpi resolution. Various kinds of media can be printed with the high speed of a maximum
8.7 pages per minute. The printing paper tray can hold up to 100 sheets of plain paper, 50 sheets of OHP film, or 10 back print films or envelopes.
*Plain paper fax which can transmit/receive in color
Conforming to ITU-T recommendations, this fax is able to transmit/receive in color. Due to containing extremely high-speed 33.6kbps modems, transmission time can be shortened. Pictures and photographs can both be send and received clearly by UHQ(Ultra High quality), Canon’s vivid image processing technology. Up to 20 letter- or A4- size sheets, or up to 10 legal-size sheets, can be set in the ADF. 12 one-touch dial entries and 100 speed dial entries can be registered, and group dial and broadcasting transmission can also be done. When paper and ink run out, the data is saved to memory, so there is no worry. When a external-phone is attached, fax communication and normal telephone reception are possible due to DRPD service and FAX/TEL switching.
BJ Cartridge
Printing quality superior to photos is produced by use of BC-30 and BC-33/BC-34 photo BJ cartridges.
*Out-of-Ink Function
This machine has a function which detects when ink has run out. It also detects when the cartridges of machines equipped with color communications are out of ink. The presence/absence of ink in the ink chamber is detected by reflecting ink sensor.
Copy Function
This machine can be used as a 360dpi × 360 dpi high resolution full color copier. With a monochrome document (including half-tone), up to 99 pages can be copied at one time at the speed of a maximum of 3 pages/minute.
Full Color & 256 Gradation Grayscale Scanner
Using graphics or OCR software which conforms to the TWAIN standard, full color and 256-gradation grayscale images with a quality of 30dpi ~ 600 dpi can be read into a computer. Reading in can be done at a resolution of 300dpi, and can be enhanced to 600dpi using the included MultiPASS Suite.
PC Fax
By connecting this machine to a computer, a fax can be transmitted from the included MultiPASS Suite or from a Windows application, and a received image can be saved to the computer as-is without printing it out.

MultiPASS C755 Chapter 2: Assembly and Disassembly
1. ATTENTION TO BE PAID DURING ASSEMBLY/ DISASSEMBLY
1.1 Safety Cautions
Electrical shock
In order to prevent any risk of electrical shock, always be sure to check that the power cord and modular jack have been removed. Also, remove all cables connecting to the computer. When conducting service that requires the main unit to be powered on, be sure to wear some kind of earthing, such as a wrist strap, etc. Otherwise, there is a danger of conduction and electrical shock. Parts which are generally likely to cause electrical shock are as follows.
• Power supply unit primary (supplied with AC voltage)
• Telephone line primary
• LBP engine high voltage contacts (for high voltage during developing and transfer)
High temperature
In order to prevent burns during disassembly, allow at least ten minutes, after the power has been switched off, for the high temperature components to cool down. General high temperature components are as follows.
• Motors
• Power supply unit
• Elements on driver ICs, etc., on PCBs (in particular, ICs with heatsinks)
• BJ cartridge aluminium plate (for BJ cartridge engine models)
• Fixing unit and peripheral covers (for LBP engines)
Fire
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.
Ignition
When using solvents such as alcohol, etc., while conducting service, there is a danger of fire igniting from heat from internal circuitry and from sparks. Before using any such solvents, be sure to switch off the power and allow time for high temperature parts to cool down. Make sure that there is sufficient ventilation when working with solvents.
Movable parts
In order to prevent accidents with movable parts, be sure to remove the power cable when conducting service that requires disassembly. Also, take care that personal accessories and hair, etc., are not caught in any moving parts.
2-1
MultiPASS C755 Chapter 2: Assembly and Disassembly
1.2 General Cautions
Damage due to electrostatic discharge
This machine contains contact sensors and printed circuit boards that use ROMs, RAMs, custom chips and other electronic components that are vulnerable to damage by electrostatic discharge. Be careful to avoid any damage from electrostatic discharge when conducting service that requires disassembly.
Static electricity warning
Electrostatic discharge can destroy electronic components and alter electrical characteristics. Plastic tools and even your hands, if they are not earthed, contain sufficient static electricity to damage electronic components.
The following materials may be used as countermeasures against electrostatic discharge:
• an earthed, conductive mat,
• an earthed wrist-strap,
• crocodile clips for the purpose of grounding metallic parts of the main unit.
For service conducted on the user’s premises, etc., where such countermeasure materials are not available, the following countermeasures may be employed.
• Use anti-static bags for the storage and carrying of PCBs and electrical elements.
• Avoid silk and polyester clothing and leather soled shoes, favouring instead cotton clothes and rubber soled shoes.
• Avoid working in a carpeted area.
• Before beginning the work, touch the grounded earth terminals of the main unit in order to discharge any static electricity.
• Use a wrist-strap and earth the metal parts of the main unit.
• PCBs and electrical elements must lifted around the edges and their terminals must not be touched.
Caution against electrical shock while working with power on
In cases where service must be carried out with power on, via a connected power cable, be sure to wear an anti-static wrist-strap or other earth, in order to prevent an electrical path being created through your body.
Application of grease
Grease must not be applied to any parts that are not so designated. If grease comes into contact with the rubber cap of the purge unit or wire, the BJ cartridge nozzle may become blocked and the cartridge rendered unusable. Also, never use any other than the specified type of grease. Otherwise, plastic parts and rubber parts may melt or be otherwise deformed.
Attaching and removing cables
Attaching and removing cables with the power still on may cause breakdowns and should be avoided. In particular, flat cables are likely to cause short circuits. When attaching or removing cables, always be sure to turn the power off.
2-2
MultiPASS C755 Chapter 2: Assembly and Disassembly
1.3 Product-Inherent Cautions
Prevention of ink-soiling
Be careful when handling the BJ ink cartridge nozzle, the ink pad, head cap, head wiper and waste ink pad. Residual ink may soil the main unit, working surfaces, your hands and clothes, etc. The ink is water­soluble, but because it contains pigments, it will not wash out of clothes.
The ink does not contain any substances that are harmful to humans, but does contain organic solvents (isopropyl alcohol 67-63-0, diethylene glycol 111-46-6, glycerin 56-81-5 and ethylene glycol 107-21-1). If the ink should accidentally get into someone’s eyes, rinse the affected eye with plenty of clean water and seek medical attention. If a large quantity of ink is accidentally swallowed, seek medical advice immediately. In such a case, let the doctor know exactly what is written on the BJ cartridge label.
Conductivity of the ink
The ink used in the BJ cartridge is conductive. This means that, if the ink leaks, mechanical parts should be wiped with a dampened paper towel or similar and electrical circuits wiped with tissue paper so that all ink is removed from below the IC chips. If power is switched on while ink is leaking on the electrical circuits, the circuitry may short out and be damaged. If ink is leaking, the power must be switched off.
1.4 Action in the Event of Abnormality (All Clear)
In the event of extreme noise or shock, etc., in very rare cases, the display may go out, and all the keys become inoperable. In that case, perform an All Clear. This operation returns all values and settings to their default settings. However, as all settings, such as received images and user data, service data, etc., will be re-initialised, be sure to note down any settings that you will need to re-enter later.
