3.1 General
This chapter explains the mechanical features, operations and procedures for dismantling and assembling the finisher driver. Ensure that the following precautions
are observed when proceeding with these tasks.
Caution Always disconnect the power supply from the socket when dismantling or reas-
sembling the device.
Unless otherwise stated, assembly procedures should be performed in the reverse
sequence to dismantling.
Care must be taken not to use the wrong screws (length, diameter) during assembly.
Never attempt to operate the device with parts removed.
Discharge static electricity from the body by touching a metal part of the printer
prior to removing or replacing circuit boards to prevent them from being d amaged through static electricity.

Caution Replace the lithium battery with SONY Lithium Cell CR2450 only. Use of another
battery may pres ent a risk of fire or explosion.
The lithium battery includes lithium, an organic catalyst and other flammable sub-
stances. The battery may present a fire or chemical burn hazard if misteated. Do
not recharge, disassemble, or dispose of in fire.
Caution Keep the battery out of reach of children and discard used battery promptly.
When disposing the lithium battery, observe the applicable local lows and ordinances.
The package of lithium battery includes a se al (➌) in order to prevent short-circuit.
When you replace the batte ry (➋), be sure to seal the new battery after you set it on
