Preparing a location for the printer

Place the machine on a level and sturdy surface that can withstand the machine weight, 22.6kg (50lb). If tilted, the machine may fall over and cause injuries.

Space requirements

The printer has ventilation holes on the side and rear panels. Ensure that the printer is installed with a minimum clearance of 255mm (10in) from the rear vent to any wall, 200mm (8in) from the left vent to any wall, and 300mm (12in) from the right vent to any wall. A poorly ventilated machine can cause excessive internal heat and fire. The following diagram shows the minimum clearances required for normal operation, consumables replacement, and maintenance to ensure your machine operates at peak performance.

Environment

Ensure that the installation location meets the following conditions:

• Do not place the printer in a hot, humid, dusty or poorly ventilated environment. Prolonged exposure to such adverse conditions can result in fire or electric shock.
• Temperature range 10 - 32^ C (50 - 89°F), humidity range 15 - 85% (no condensation). Humidity should be 70% or below at 32^ C (89°F), and temperature should be 28^ C (82°F) or below at 85% humidity.

NOTE

Sudden temperature fluctuations can affect print quality. Rapid heating of a cold room or moving the printer from a location with low humidity/temperature to high humidity/temperature can cause condensation inside the printer, directly interfering with image transfer. When condensation occurs, leave the printer for at least 1 hour to acclimate to the environment before using it.

• Do not expose the printer to direct sunlight.
• Do not expose the printer to the direct draft of air-conditioning or heating.

Installing the Face Up (Rear) Tray

1. Insert the right and left tabs of the face up (rear) tray into the holes at the back of the printer (1), and lower the tray into position (2).

1. Push up the rear output tray lever as shown in the diagram (1) and pull out the extension tray (2).

Installing the Drum-Toner Cartridge

NOTE

Your printer is supplied with a drum-toner cartridge with an approximate capacity of 6,000 Letter pages at 5% coverage. Replacement drum-toner cartridges are available with approximate capacities of 6,000 pages or 10,000 pages.

When handling the drum-toner cartridge, take note of the following points:

WARNING!

Never throw a drum-toner cartridge into an open flame as it can cause an explosion.

• Do not subject the drum-toner cartridge to direct sunlight or strong light.
• When installing the drum-toner cartridge, select a location not subject to strong light and try to finish the installation within 5 minutes.
• Do not touch the surface of the photosensitive drum. Do not let the drum-toner cartridge stand upside down or place it upside down as this may damage the drum.
• A drum shutter protects the photosensitive drum from light. Do not open the drum shutter.
  Although the toner is not harmful to the body, wash it off immediately with cold water if your hands or clothes are in contact with it.
  It is recommended to use up the drum-toner cartridge within one year of removing it from its packaging.
• Keep the drum-toner cartridge out of the reach of children.

1. Open the cover.

NOTE

When the optional offset catch tray is installed, fold the tray first before opening the cover.

WARNING!

Do not touch any parts inside the printer.

1. Take the drum-toner cartridge out of the packaging box and shake it seven or eight times as shown in the diagram.

1. Place the drum-toner cartridge on a flat surface and pull out the seal horizontally.

CAUTION!

When pulling out the seal, pull it out horizontally. The tape might break if it is pulled out diagonally.

After the seal has been pulled out, do not shake or bump the drum-toner cartridge.

1. Hold the drum-toner cartridge by the grip and insert it into the slot inside the printer.

CAUTION!

Do not touch any parts inside the printer. Ensure that the drum-toner cartridge is firmly located.

1. Close the cover securely.

NOTE

If the offset catch tray is folded as in Step 1, close the cover and then return the tray to its original position.

Cables

Connecting an interface cable

Connect the interface cable to be used to the printer.

NOTE

Connect a USB cable only after the printer driver has been installed on the computer.

1. Connect the interface cable to the interface connector at the back of the printer: serial (1), USB (2), network (3), parallel (4).

For a parallel cable, lift up the wire clip on both sides to secure it after it has been inserted into the connector.

1. For Parallel, USB, or Serial cables, connect the other end of the cable to the interface connector of the computer.

Connecting the power cord

When connecting the power cord, take heed of the information given in "Safety precautions" on page 3.

1. Close the lid of the paper tray and push the tray completely into the printer.

CAUTION!

The lid of the tray must be firmly closed. If not, the paper may become misaligned.

1. Depending on the types and sizes of the loaded paper, you need to configure settings on the control panel. Change the paper type when non-plain paper such as recycled paper, heavyweight paper or transparencies is loaded. Configure the paper size when custom size paper is loaded.
