LASER CLASS 730i/720i/710 Chapter 3: Assembly and Disassembly
3-1
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)
Battery Replacement
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.
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.
