3. Safety Information

To prevent an accident while working on the printer, strictly observe described in this manual. Never conduct dangerous operations or operations not in this manual. There may be several dangerous things other than those described below, always work with extreme caution for safety reasons.

warnings

and

cautions

3.1 Safety Components

This printer has safety components to protect from accidents to occur (fuse, thermostat, interlock switches and so on) and safety component for user operation (cover , panel and so on). They must be kept in their operational state. Never modify the printer (especially of the safety components).

3.2 Laser Beam

To avoid exposure to the laser beam, this printer is equipped with the two safety switches; Interlock Switch and CRU Switch in the CR U Sensor Assembly. The Interlock Switch turns OFF when opening covers and stops supply of the power. The CRU Switch cuts the circuit when the EP Cartridge is removed and stops power supply to the circuit of the output of the laser beam.

Caution : 1. Direct eye exposure to the laser beam may cause eye injury or blindness.

2. Never open the covers in which a warning label on the laser beam is sealed.

3. Switch OFF the printer power when you perform removal and reinstallation of the printer.

4. Be sure to follow the procedure described in this manual when you work on the printer during its operation.

5. Remove the EP Cartridge before you press the Interlock Switch by hand or tools during maintenance operation. (Do not turn on the Interlock Switch and CRU Switch at the same time.)

6. Recognize the character of the laser beam and the dangers that are involved that can inﬂict harm to the human body, and take precaution when handling the laser beam in order to avoid injury to you and those around you.

Note : The laser beam is characterized by a very small range of wave lengths and the similar

phase of waves, in contrast with other light (the light of the sun and that of an electric lamp, for example). Therefore, the laser beam is monochromatic and has a high focusability, and can reach long distance in a thin beam. The thin laser beam has a very high energy density and high temperature and can inﬂict injury to the human body.

Memo : The laser beam used for this printer is invisible and you cannot see it.

3.3 Power

When working on the printer, be sure to switch off the printer power and unplug the power cord to avoid electric shock, burn or injury.

When it is necessary to work with the power on such as when measuring the voltage, conduct the work with great care to avoid an electric shock and follow the procedures described in this manual.

Warning : Do not touch live parts other than those necessary to do so when working on the

printer when power on. The power switch/inlet section (LVPS Assembly) is supplied with power even if the power is switched OFF, therefore never touch the live parts.

3.4 Driving Sections

When working on the driving sections such as gears, to avoid injury, make sure to switch the power OFF, disconnect the power cord, and rotate gears by hand (hand crank).

Warning : Never touch the gears while the printer is in operation.

Introduction — LaserWriter 10/600 A3+ 1 – 6

3.5 High Temperature Sections

When working on the high temperature sections such as fuser component, to avoid burn or injury, make sure to switch the power OFF, disconnect the power cord, and begin to work after the temperature of the component has gone down signiﬁcantly.

Caution : The temperature is high just after the printer operates, therefore begin to work after let-

ting the component cool down.

3.6 Warning / Caution Labels

Warning and caution labels are sealed on dangerous parts in the printer to warn and prevent accident. Check whether these labels are ﬁrmly sealed in place and are not soiled when performing maintenance or repair.

3.6.1 Laser Warning Label

To avoid direct exposure of the laser beam to the engineer, a laser warning label is sealed on top of the laser output unit (ROS Assembly).

Page 10

Introduction — LaserWriter 10/600 A3+ 1 – 7

3.6.2 High Temperature Caution Label

To avoid burn of customers, caution labels are sealed on top of the fuser unit (Fuser Assembly).

3.6.3 High Voltage Caution Label

To reduce the risk of electric shocks to the engineer, caution labels are sealed on top of the frame (Main Frame Assembly) which is on top of the high voltage power supply (HVPS)
