[1] Caution

1. Laser caution

This laser printer 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 does 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 is not 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.

3. Caution for Battery replacement

FO-DC635U

(Danish) ADVARSEL !

Lithiumbatteri-Eksplosionsfare ved fejlagtig håndtering.

Udskiftning må kun ske med batteri af samme fabrikat og type.

Levér det brugte batteri tilbage til leverandoren.

(English) Caution !

Danger of explosion if battery is incorrectly replaced.

Replace only with the same or equivalent type

recommended by the equipment manufacturer.

Discard used batteries according to manufacturer's instructions.

(Finnish) VAROITUS

Paristo voi räjähtää, jos se on virheellisesti asennettu.

Vaihda paristo ainoastaan laitevalmistajan suosittelemaan

tyyppiin. Hävitä käytetty paristo valmistajan ohjeiden mukaisesti.

4. Precautions for using Lead-Free Solder

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:

(French) ATTENTION

Il y a danger d'explosion s' il y a remplacement incorrect

de la batterie. Remplacer uniquement avec une batterie du

même type ou d'un type recommandé par le constructeur.

Mettre au rébut les batteries usagées conformément aux

instructions du fabricant.

(Swedish) VARNING

Explosionsfare vid felaktigt batteribyte.

Använd samma batterityp eller en ekvivalent

typ som rekommenderas av apparattillverkaren.

Kassera använt batteri enligt fabrikantens

instruktion.

(German) Achtung

Explosionsgefahr bei Verwendung inkorrekter Batterien.

Als Ersatzbatterien dürfen nur Batterien vom gleichen Typ oder

vom Hersteller empfohlene Batterien verwendet werden.

Entsorgung der gebrauchten Batterien nur nach den vom

Hersteller angegebenen Anweisungen.

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. Toreduce bit wear, care should be taken to clean the bit thoroughly after each use.

4. Cautions on Transmitting Documents

• Documents written in yellow, greenish yellow, or light blue ink cannot be transmitted.

• Ink, glue, and correcting fluid on documents must be dry before the documents can be transmitted.

• All clips, staples and pins must be removed from documents before transmission.

• Patched (taped) documents should be copied first on a copier and then the copies used for transmission.

• All documents should be fanned before insertion into the feeder to prevent possible double feeds.

5. Automatic Document Feeder Capacity

Number of pages that can be placed into the feeder at anytime is as follows:

Normal size: max. 50 sheets (14 lbs - 20 lbs)

Special size: single sheet only (manual feed)

NOTE: • If you need to send or copy more 50 pages, place the addi-

tional pages and carefully in the feeder just before the last page is scanned. Do not try to force them in, as this may cause double-feeding or jamming.

• If your document consists of several large or thick pages which must be loaded one at a time, insert each page into the feeder as the previous page is being scanned. Insert gently to prevent double feeding.

6. Readable Width & Length

The readable width and length of a document are slightly smaller than the actual document size.

[5] Installation

1. Site selection

Take the following points into consideration when selecting a site for this model.

ENVIRONMENT

• The machine must be installed on a level surface.

• Keep the machine away from air conditioners, heaters, direct sunlight, and dust.

• Provide easy access to the front, back, and sides of the machine. In particular, keep the area in front of the machine clear, or the original document may jam as it comes out after scanning.

• The temperature should be between 50 - 86°F (10 - 30°C).

• The humidity should be between 20% and 85% (without condensation).

ELECTRICITY

AC 120V, 60Hz, grounded AC (3-prong) outlet.

Caution!

• Connection to a power source other than that specified will cause damage to the equipment and is not covered under the warranty.

• If your area experiences a high incidence of lightning or power surges, we recommend that you install a surge protector for the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores.

TELEPHONE JACK

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

• Plugging the fax machine into a jack which is not an RJ11C jack may result in damage to the machine or your telephone system. If you do not know what kind of jack you have, or need to have one installed, contact the telephone company.

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

If the machine is moved from a cold to a warm place, it is possible that the reading glass may fog up, preventing proper scanning of documents for transmission. To remove the fog, turn on the power and wait approximately 2 hours before using the machine.

2) Connecting the telephone line cord

Insert one end of the line cord into the jack on the back of the machine marked TEL. LINE. Insert the other end into a standard (RJ11C) single-line wall telephone jack.

Note: The fax machine is set for touch-tone dialing. If you are on a pulse dial (rotary) line, you must set the fax machine for pulse dialing by changing Option Setting 22.

3) Attaching the ADF exit tray

Insert the protrusion on the right side of the machine into the hole in

the right side of the ADF exit tray , then bend the tray

slightly and insert so that the protrusion on the left side of the machine goes into the hole on the left side of the ADF exit tray

. Pull out the tray extension .

2. Assembly and connections

1) Connecting the power cord

Connect the female end of the power cord to the fax machine as shown. Insert the male end into a 120 V, 60 Hz, grounded (3-prong) AC outlet.

Important!: The fax machine requires its own dedicated power outlet. The power outlet must not be shared with any other devices. In particular, do not use an extension cord to connect multiple devices to the outlet.

Note: If your area experiences a high incidence of lightning or power surges, we recommend that you install surge protectors for the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores.

Press the power switch to turn on the power.

4) Attaching the received document tray

Slide the received document tray into the machine as shown. When it stops, lift the end slightly and push in so that the tray locks into place.

Important!: The received document tray must be attached for the fax machine to operate properly.

1 – 7

3. Installing the print cartridges (Toner cartridge:

FO-50ND)(Drum cartridge: FO-47DR)

Follow the steps below to install or replace the toner and drum cartridges.

• The initial starter toner cartridge included with the fax machine can print approximately 3000 letter-size pages (4% coverage of each page; continuous printing).

• The replacement toner cartridge (FO-50ND) can print approximately 6000 letter-size pages.

• The drum cartridge (FO-47DR) can print approximately 20,000 letter-size pages.

1) Press the cover release to open the print compartment cover.

• Caution! The fusing unit inside the print compartment becomes very hot during operation. Be careful not to touch the inside of the compartment.

FO-DC635U

3) If you are replacing the drum cartridge, remove the old cartridge and dispose of it according to local regulations.

4) Remove the new drum cartridge from its packaging. Insert the drum cartridge into the print compartment.

• Caution! Excessive exposure to light will damage the drum car-

tridge. Install the cartridge promptly after removing it from its packaging.

• Make sure the drum cartridge is inserted in as far as it will go.

BLUE

2) If you are replacing the toner cartridge, remove the old cartridge and dispose of it according to local regulations.

Go directly to STEP 5 if you are only replacing the toner cartridge and not the drum cartridge.

To make the cartridge more compact for disposal, press the buttons on the ends of the handle and fold the handle down.

• If you are replacing the drum cartridge but not the toner car-

tridge, remove the toner cartridge and place it on a sheet of paper.

GREEN

5) If you are installing a new toner cartridge, remove the new toner cartridge from its packaging. Remove the tape from the cartridge and then open the cartridge handle so that it stands straight up.

6) Shake as indicated by the arrows to distribute the toner evenly within the cartridge.

• If the toner is still lumpy after shaking, the gears in the cartridge

may make a noticeable sound when the print compartment cover is closed after installing the cartridge. This is normal and does not indicate a problem.

2.1.13 (M) All FAX/TEL. entry mode

This is a function to copy the FAX and TEL numbers registered in the one-touch dialing (RAPID) key [01] to the all one-touch dialing (RAPID) key and the all abbreviated number (SPEED DIAL) to simplify the FAX and TEL number registration at the time of aging. (Only the EMAIL can be used for the network models.)

1. Copy the FAX/TEL number or the E-MAIL stored in the RAPID key [01] to all RAPID keys.

2. Copy the FAX/TEL number or the E-MAIL stored in the RAPID key [01] to all SPEED DIAL numbers.

3. If the chain dial is not set for the RAPID key, or RAPID key [01] stores the E-MAIL, the RAPID keys [02] – [59] and all SPEED DIAL numbers are stored in the group number [01].

4. Enter all registered one-touch send (RAPID) keys and speed dial numbers (SPEED DIAL) on the personal books [01] - [10]. Following this, set the password registration and the password setting to ON, and set the TTI setting to OFF.

The call-receiver names and book names are specified as follows:

Rapid R XX XX : Rapid key send SPEED DIAL S XXX XXX : Speed dial number Personal book BOOK XX XX : Book number

FO-DC635U

NOTE: Before entering this mode, a FAX/TEL number or an E-MAIL

must be stored in the RAPID key [01]. (This program will not be executed if there is no data stored, or otherwise a program or a group is registered.)

2.1.14 (N) Dept. passcode

The department passcode list is printed.

2.1.15 (O) Conf. passcode

The confidential passcode list is printed. Differing from printing of one box alone soon after registration, the confidential passcodes of all boxes are printed.

2.1.16 (P) Signal send mode 2

The signals concerned with V.34 & V.8 are checked. It can be used to check the modem. When the START key is pressed, silence signal (make loop) will be executed. The following signals are sent by pressing the START key thereafter.

[1] No signals (mark loop) [10] 14400BPS (V. 34) [2] 33600BPS (V. 34) [11] 12000BPS (V. 34) [3] 31200BPS (V. 34) [12] 9600BPS (V. 34) [4] 28800BPS (V. 34) [13] 7200BPS (V. 34) [5] 26400BPS (V. 34) [14] 4800BPS (V. 34) [6] 24000BPS (V. 34) [15] 2400BPS (V. 34) [7] 21600BPS (V. 34) [16] 0 - 300BPS (V. 34) [8] 19200BPS (V. 34) [17] ANSam [9] 16800BPS (V. 34)

2.1.17 (Q) Memory set mode

The set and dump list of the memory content is output.

MEMORY SET MODE AD = 00000000

Cursor

• The address (8 digits (P) generally including the bank information is input, and the data of 2 digits is continuously input. Inputting is done in the hexadecimal mode. The ten-key is used for 0 through 9, and the alphabetic keys A (RAPID 01 through 06) are used for A through F.

MEMORY SET MODE AD = A02800F6 DATA = 0B

• During data inputting, the address can be moved forward and back-

ward one byte by one byte with " " and "#". (The address prior to the address 0 is looped as the maximum address.)

• The Validity of the address is not checked. Accordingly, writing/ reading operations are possible in the address of the memory not assigned, the address of ROM and so on. (However, as practical, writing is not done, and the data content runs short each reading.) Though writing is possible in the flash memory, a little time is required. It is also necessary to take care that the life of the flash memory is excessively shortened if much data is written in the flash memory. Since it may run away depending the written content, take minute care for the writing address.

(The letters after 16th letter of the call-receiver’s name registered in the one-touch dialing [01] are cut off.)

• When the REPORT key is input, the memory dump list is produced from the displayed address (here, it is limited at the 16-byte boundary address (address with end 0) which does not exceed the specified address and is just in front.). The dump list is output to a maximum of 99 pages. If any data of one page can be repeatedly developed and printed, the list is sufficient. But it is not desired that the content of plural pages are developed in the memory once and are then printed. If the STOP key is pressed, it will pass to the diagnosis after the page which is now being printed is completed printed. If the address exceeds the maximum address, it will return to the address 0 and printing will be continued.
