The rated life expectancy of each consumable is based on printing under specific operating conditions such as page coverage for a particular page size (5% coverage per color at 600 x 600 dpi resolution on A4 size paper). The actual consumable life will vary depending on its use and other printing variables including page coverage, page size, media type, print resolution, continues or intermittent printing, number of color planes, ambient temperature and humidity.

2 About Lead Free Solder

DP-CL18

2.1. Suggested PbF Solder

We recommend you to use the following solder when re-soldering component for repair. Before using other Pb free solder than the following solder, be sure to confirm a solder maker you appoint has made license agreements to be required when using Pb free solder legally.

Supplier: Senju Metal Industry Co., Ltd. (http://www.senju-m.co.jp) Part Description in Senju: ECO SOLDER RMA02 P3 M705 Series

Note:

When the recommended PbF solder is not available at Senju Metal Industry Co., Ltd., see section 14.10 PbF Solder Service Part Number.

3.3. Repacking

Prepare the unit before shipping.

Note:

It is highly recommended that users keep the original carton and All packing materials. Please follow these instructions when moving the printer.

· Please use the original carton and all of the original packing material.

· Improper repacking of the printer may result in a charge to repair the unit or a cleaning charge to remove spilled toner.

· Since the printer uses dry toner, extreme care must be taken when handling. The printer should be handled in the upright

(vertical) position.

· Original carton and packing materials

· Newspaper or drop cloth

· Shipping tape and scissors

Turn off the printer, remove the power code and all interface cables.

Open the right cover (right side door).

Slide the green lever for the waste toner cartridge to the right (RELEASE).

Unlock the two levers (1) and open the print cartridge holder (2).

Pull out the color print cartridge halfway and remove it (2) while pressing the green stopper (1) on the left side.

Remove the waste toner cartridge.

Be sure the green lever is in the RELEASE position so that upper openings to waste toner cartridge are completely closed.

Insert the waste toner cartridge into a plastic bag and seal the end of the bag tightly.

Note:

To prevent damage to the print cartridge;

- Do not touch the green drum surface.

- Do not expose to light for more than 45 minutes.

Close the PC shutter and wipe off any loose toner on the color print cartridge using a toner vacuum. Do not use a standard office vacuum; the toner will not be retained by typical vacuum dust collectors.

Caution 1:

If replacing the upper seal cover though the toner is on the color print cartridge, the toner will be scattered when removing the upper seal cover. The scattered toner may be attached to the OPC drum and the poor print quality will be caused.

Caution 2:

If the print cartridge is wiped using a toner vacuum when the PC shutter is opening, the toner in the print cartridge is sucked and charged. This charge is discharged to the OPC drum and the OPC drum may be damaged. Wipe off the toner on the print cartridge using care that the PC shutter is not opened.

Move the PC shutter in this arrow direction to close the PC shutter.

Replace the protective tray (1), upper seal covers (2-4)

and protective caps (5).

Be sure the three sealing levers of the print cartridge are exposed through the lower seal cover.
