Safety and

Precautions

FAX-L1000 Chapter 1: Safety and Precautions

1.DANGER TO PERSONNEL

1.1Electric Shock

Precautions

Before disassembling the fax, carry out the following to prevent electric shock:

(1)Disconnect the power cord from the outlet.

(2)Disconnect the modular jack cord (telephone line) from the fax.

Precautions when servicing the fax with the power on

When you must service the fax with the power cord plugged in, you must not ground your body with grounding wrist straps.

This is to prevent electricity passing to your body.

1-1

FAX-L1000 Chapter 1: Safety and Precautions

1.1.1 AC line (AC 230V household current)

Power supply unit (primary side)

The AC 230V is supplied to the primary side of the power supply unit when the power cord is plugged in.

1.1.2 Telephone line

NCU board (primary side)

When connected to the telephone line, a line voltage of approx. DC 48V is supplied to the fax from the telephone line.

And when the ringing signal is received, approx. AC 90Vrms is supplied.

1.1.3 Printer high voltage terminal

When the printer cover sensor is pressed with the printer cover closed, voltage of approx. AC 1600V p-p maximum is supplied to the printer high voltage terminal. When you press the printer cover sensor, be careful not to touch the high voltage terminal.

FAX-L1000 Chapter 1: Safety and Precautions

1.2 High Temperature Parts

Precautions

To prevent burns while disassembling the fax, disconnect the power cord at least 10 minutes before starting disassembly, to allow high temperature parts to cool down.

How to treat burns

Heat of about 122°F (50°C) or more causes burns. Also, the longer the contact, the more severe the burn.

When treating a burn, the first minute after receiving the burn is the most important. Cool the burn immediately with cold running water. In the case of a serious burn, seek medical attention immediately.

The temperatures of the parts shown below become more than 50°C during operation. Be Careful not to burn yourself on any of these parts during servicing.

1.3 Fire

Danger

Do not throw the lithium battery or the toner cartridge into fire.

Lithium battery

The lithium battery contain lithium, organic solvents and other combustible substances. If the lithium battery is thrown into fires, it may rupture and burn fiercely.

Toner

The toner in the toner cartridge contains flammable substances.

The danger of fire exists with toner scattered around in a tightly-closed room.

Follow local applicable laws and regulations when disposing of the lithium battery or the toner cartridge.

FAX-L1000 Chapter 1: Safety and Precautions

1.4 Moving and Rotating Parts

Precautions

To prevent accidents involving moving or rotating parts during servicing, that disconnect the power cord before starting disassembly.

When you must service the fax with the power cord plugged in, you must not wear bracelets, necklaces, neckties, or other objects. Also, take care to prevent hair and other articles of clothing from becoming entangled.

The fax is provided with a protection function which stops moving and rotating parts in the printer, when the printer cover is opened during operation. However, if these sensors have to be moved when carrying out servicing with the power cord plugged in, moving and rotating parts will operate even with these covers open.

Since this fax does not have a sensor to detect when the right cover or left cover is removed, even if you open the front cover or rear cover while this fax

is operating, the gears and rollers continue to move.

1.5 Laser Beams

This fax is a Class 1 Laser Product as defined in the EN60825 (IEC825) Radiation Safety of laser products, equipment classification, requirements and user’s guide. This means that this product uses lasers that do not radiate dangerous laser beam and conforms to the regulations because the laser beam does not affect the user during operations.

Warning

If the LASER light gets in your eyes, it will damage the retina. Figure 1-4 is a LASER beam warning label which is placed on the LASER/scanner unit. Always remain within the contents of this manual when servicing, and do not carry out any other maintenance. Within the range of service work in this manual, you will not be exposed to dangerous LASER light.

Figure 1-4 LASER beam warning label

Disassembly Prohibited

Never disassemble or alter the printer section laser/scanner unit. There is no servicing that requires you to disassemble the laser/scanner unit.

Safety Mechanism

This fax is designed with a structure such that the laser shutter only opens

when the toner cartridge has been inserted into this fax. This keeps the laser

NOTE

from operating other than during normal operations.

2.DANGER TO EQUIPMENT

2.1Handling the FAX

General Precautions

TO AVOID SERIOUS INJURY, NEVER DISASSEMBLE

THE FAX. EXPOSED POWER POINTS INSIDE THE FAX CAN CAUSE ELECTRICAL SHOCK IF YOU TOUCH THEM.

After you unplug the fax unit, always wait at least 5 seconds before you plug it in again. Always unplug before you move the fax.

During electrical storms, disconnect the plug from the power outlet. The fax can hold documents in the memory for up to 12 hours.

Before you attach or remove the plug from the power outlet, make sure your hands are dry.

Do not stack boxes or furniture around the power outlet.

Keep the area open so you can reach the outlet quickly. If you notice anything unusual (smoke, strange odors, noises) around the fax, turn the fax off immediately and unplug it. Call for service.
