Safety information

Laser safety

This printer is certified as a Class 1 laser product under the U.S. Department of Health and Human Services ( Safety Act of 1968. This means that the printer does not produce hazardous laser radiation. Since radiation emitted inside the printer is completely confined within protective housings and external covers, the laser beam cannot escape from the printer during any phase of user operation.

) Radiation Performance Standard according to Radiation Control for Health and

DHHS

Laser notice

The printer is certified in the U.S. to conform to the requirements of

DHHS

Subchapter for

CFR

Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements of

IEC

825.

Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) laser that is nominally a 5 milliwatt laser operating in the wavelength region of 780 nanometers. The laser system and printer are designed so there is never any human access to laser radiation above a Class I level during normal operation, user maintenance, or prescribed service condition.

Laser product labels are located on top of the laser scanner:

Warning - Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

CDRH regulations

The Center of Devices and Radiological Health (

) of the U.S. Food and Drug Administration

CDRH

implemented regulations for laser products on August 2, 1976. These regulations apply to laser products manufactured after August 1, 1976. Compliance is mandatory for products marketed in the United States. A label indicating compliance with the

regulations must be attached to

CDRH

laser products marketed in the United States.

Ozone concentration

Laser printers generate ozone gas (O

) which may concentrate in the place of installation and

cause an unpleasant smell. To minimize the concentration of ozone gas, we recommend that the laser printer not be installed in a confined area lacking ventilation.

FCC notice

This device complies with Part 15 of the

Rules. Operation is subject to the following two

FCC

conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the

Rules. These limits are designed to provide reasonable protection

FCC

against harmful interference in a residential installation. Th is equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communication. However, there is no guarantee that interference will not occur in a particular installation.

If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an ou tlet o n a circuit different from that to which the receiver is connected.

Consult the dealer or an experienced radio/

technician for help.

Change or modifications not expressly approved by the manufacturer for compliance could void the user’s authority to operate the equipm en t.

Interference cable to the computer shall be used with shielded circular cable. Any modification without prior permission may cause harmful interface. If any

Important note on the interface connectors

Be sure to turn off printer power before connecting or disconnecting an interface cable to the printer. For protection against static discharge which may be applied to the printer's internal electronics through the interface connector(s), keep any interface connector which is not in use capped using the protective cap supplied.

Warning - This equipment has been certified to comply with the limits for a Class B computing device, pursuant to Subpart J of Part 15 of FCC Rules. Only peripherals (computer input/output devices, terminals, etc.) certified to comply with the Class B limits may be attached to this equipment. Operation with non-certified peripherals is likely to result in interference to radio and TV reception.

Places to avoid

Avoid installing the printer in locations exposed to:

• Direct drafts of hot or cold air.

• Direct drafts of outside air. (Avoid locations next to outside doors.)

Product information

• Sudden temperature or humidity changes.

• Any source of high heat, such as a radiator or stove.

• Excessive dust. Dust and smoke may cause contamination on the laser scanner window,

causing print quality problem.

• Vibration.

• Ammonia fumes or other harmful fumes. (In case of humigating the room or saturate it with

insecticide, remove the printer first.)

• Avoid greenhouse-like rooms. (Because of sunlight and humidity.)

• Avoid enclosed spaces that block v e ntilation.

• Avoid sites more than 6500 feet or 2000 meters above sea level.

POWER REQUIRMENTS

• Disconnect the printer from the power source before attempting removal or re-placement of an

electrical component or a printed-circuit board.

• The printer should not be connected to a power source until the instruction is given to do so

when performing tests described in this manual.

• In connecting the printer power, exercise an extreme care in handling the power supply or any

other electric parts which may give an electric shock.

• Before performing maintenance or repair, power from both the power source and the

associated peripheral devices (computer, sorter, etc.) should be disconnected, unless otherwise specified.

• To avoid possible electrical shock, extreme caution must be exercised in handling the power

cord and any other electrical part.

Warning!

Warning!Warning!

on page 1-6). Do not use other power sources.

As the disconnect device is not incorporated in the printer's AC primary circuit, an easily accessible socket outlet must be provided near the equipment.

If the printer is used with the optional Sorter (SO-6) or Stacker (ST-20), in order to avoid shortcircuiting, it should be ensured that these devices are plugged securely into their respective power outlets.

Da kein Trennschalter in den Wechselstrom-Primärkreis des Druckers eingebaut ist, muß eine leicht zugängliche Steckdose in der Nähe des Gerätes vorhanden sein.

Wenn der Drucker mit dem gesonderten Sorter (SO-6) oder Stapler (ST-20) verwendet wird, muß darauf geachtet werden, daß diese Geräte einwandfrei an separate Steckdosen angeschlossen sind, um Kurzschluß zu vermeiden.

About the toner

The printer should use Kyocera TK-25 Toner Kit. To ensure the high print quality and long service life, the following handling precautions should apply.

Caution - As the Ecosys printers are designed to ensure the optimum print quality when used with the Kyocera’s proprietary toner, Kyocera do not recommend to use any refilled toner containers that may be available commercially. This is because Kyocera have no means for control over how such refilled toner could affect the print quality and the reliability of the printer.

Product information

About the toner

Toner container handling

To loosen and mix the toner inside, with the label side down, thoroughly shake the toner container (in the direction of the arrow) ten times or more.

Do not attempt to disassemble or refill the toner container.
