- Be sure not to touch high-voltage sections such as the chargers, transfer belt, 2nd transfer roller,
developer, high-voltage transformer, exposure lamp control inverter, inverter for the LCD back-
light and power supply unit. Especially, the board of these components should not be touched
since the electric charge may remain in the capacitors, etc. on them even after the power is
turned OFF.
- Make sure that the equipment will not operate before touching potentially dangerous places (e.g.
rotating/operating sections such as gears, belts pulleys, fans and laser beam exit of the laser
optical unit).
- Be careful when removing the covers since there might be the parts with very sharp edges
underneath.
- When servicing the equipment with the power turned ON, be sure not to touch live sections and
rotating/operating sections. Avoid exposing your eyes to laser beam.
- Use designated jigs and tools.
- Use recommended measuring instruments or equivalents.
- Return the equipment to the original state and check the operation when the service is finished.
- Be very careful to treat the touch panel gently and never hit it. Breaking the surface could cause
malfunctions.
3. Important Service Parts for Safety
- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, batteries, IC-RAMs including
lithium batteries, etc. are particularly important for safety. Be sure to handle/install them properly.
If these parts are short-circuited and their functions become ineffective, they may result in fatal
accidents such as burnout. Do not allow a short-circuit or do not use the parts not recommended
by Toshiba TEC Corporation.
