CHAPTER 1. GENERAL DESCRIPTION

[1] Caution

1. Laser caution

This laser facsimile is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH or IEC60825-1 standard. This means that
this machine dose not produce a hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.

This laser radiation isn't a danger to the skin, but when an exact focusing of the laser beam is achieved on the eyes retina, there is danger of spot
damage to the retina.

The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not an individual part.

2) Do not look into the machine with the main switch turned on after removing the toner/developer unit and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical sys­tem.

4) The cover of Laser Printer Unit contains the safety interlock switch.

Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

1. Employing lead-free solder

This model employs lead-free solder.

This is indicated by the "LF" symbol printed on the PWB and in the service manual.

The suffix letter indicates the alloy type of the solder.

Example:

Indicates lead-free solder of tin, silver and copper.

2. Using lead-free solder

When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may

result in cold soldered joints and damage to printed patterns.)

As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommended that a

dedicated bit is used, and that the iron temperature is adjusted accordingly.

3. Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer melting point (flow), to prevent damage to the

land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time.

Remove the bit as soon as a good flow is achieved.

The high content of tin in lead free solder will cause premature corrosion of the bit.

To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.

Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their

characteristics, making good soldering more difficult.

It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be

taken to clean the bit thoroughly after each use.

most telephone specialty stores.

If the machine is moved from a cold to a warm place...

Condensation may form on the reading glass if machine is moved from
a cold to a warm place, this will prevent proper scanning of documents
for transmission. Turn on the power and wait approximately 2 hours
before using machine.

TELEPHONE JACK

A standard telephone jack must be located near the machine. This is
the telephone jack commonly used in most homes and offices.

• The language is unclear in this part. Perhaps it could say:

"Plugging the fax machine into a jack which is not a standard ana­log telephone jack, may result in damage to the machine or your
telephone system."

• Do not plug the power cord into any other kind of outlet. This will
damage the machine and is not covered under the warranty.

5. Connecting the telephone line cord

Insert one end of the line cord into the socket on the back of the
machine marked TEL. LINE. Insert the other end into a wall telephone
socket.

6. Affixing the rapid key labels

Affix each strip of Rapid Key labels above each row of letter keys as
shown in the panel illustration.

7. Connecting the machine to your network

To use the Scan to E-mail and Scan to Folder functions, and to use the
machine as a printer, you must connect the machine to an Ethernet
network. In addition, to use Scan to E-mail, the network must have an
Internet connection. A typical setup is shown below.

The machine is connected using an Ethernet cable (not included).
Please purchase a 10Base-T/100Base-TX straight-through (regular)
cable.

Connect one end of the cable to the LAN port on the machine. Con­nect the other end to a LAN port on your switch or hub.

• If you are uncertain which port to connect the cable to, see the
manual for the router, switch or hub.

• The connections can be made with all devices powered on.

8. Installing the toner cartridge and drum cartridge

The laser printer in the machine uses a toner cartridge and a drum car­tridge.

• The starter toner cartridge included with the machine can print
approximately 1500 letter-size pages at 5% page coverage.

• When replacing the toner cartridge, use a SHARP FO-25ND toner
cartridge. One cartridge can print about 3000 letter-size pages at
5% coverage.

• The drum cartridge can print approximately 20,000 letter-size
pages. When replacing the drum cartridge, use a SHARP FO-
25DR drum cartridge.

Follow the steps below to install the toner cartridge and the drum car­tridge.

Note: The quality of the toner cartridge is guaranteed for 18 months
after the date of manufacture indicated on the package. The quality of
the drum cartridge is guaranteed for 24 months after the date of manu­facture indicated on the package.
