PRODUCT INFORMATION

CANON LBP-2410 REV.0 FEB. 2003

CHAPTER 1 PRODUCT INFORMATION

1 FEATURES

1.1.1 Compact color printer

The depth dimension of this printer is narrowed down by miniaturizing the image formation system units such as ITB unit, rotary, etc. The weight of it is reduced by adopting a molded-plastic body frame, simplifying mechanical units, and making the multi-purpose tray the only pick-up source in the printer.

1.1.2 Reduced wait time and low power consumption

This printer has realized wait time reduction and energy saving as compared to the models using the roller fixing method by adopting the on-demand fixing method.

1.1.3 EP-87 DRUM CARTRIDGE

The drum cartridge, ITB unit, and ITB toner case are integrated into the EP-87 drum cartridge. This allows the burdensome replacement procedure of consumable parts to be minimized for users. It resulted in the enhancement of user maintenance.

1.1.4 Employment of Canon Advanced Printing Technology

With Canon Advanced Printing Technology, data can be processed within a host computer.

This frees the printer from the PDL conversion and image processing, increasing the speed perforance and reducing the cost.

		220 - 240 V (±	10 %), 50/60 Hz (± 2 Hz)
16)	Option	Universal 250-sheet paper feeder

Note 1. Print speed when room temperature is 20 °C and the rated power voltage is input. The printing speed may progressively decrease according to the settings of paper size, paper type, number of prints to make, and the selected fixing mode.

Note 2. Time after the printer receives a print command from the interface controller when it is in ready status until it finishes printing A4 or LTR size paper and delivers it out on the facedown tray.

Note 3. When cartridge is exchanged and a power is turn on, a wait time serves as the maximum.

Note 4. When the average print coverage is a 4 % dot ratio (equivalent to about 5 % image print ratio) with the print density setting at mid point.

Note 5. OHP sheets cannot be printed in colors.

Note 6. Paper smaller than 140 mm in length cannot be delivered out faced down due to the shortage of a distance between the delivery rollers.

Note 7. It includes a peak that lasts for longer than one second.

3 SAFETY INFORMATION

3.1 Laser Safety

The laser/scanner unit emits invisible laser beam. DO NOT disassemble the unit as the laser beam can possibly damage your eyes. The unit cannot be adjusted in the field. The following label is attached to the cover of the unit:

F01-301-01

3.2 Toner Safety

Toner is a harmless substance composed of plastics and a small amount of pigment.

If you get toner on your skin or clothes, remove as much as possible with dry tissue and then wash it with cold water. If you wash in hot water, the toner gels and becomes hard to remove. As toner easily decomposes vinyl material, do not let it come into contact with the material.

3.3 Ozone Safety

An infinitesimal amount of ozone gas (O3) is generated during corona discharge from the cleaning charging roller used in this printer. The ozone gas is emitted only when the printer is operating.

The printer meets the ozone emission standard decided by the Underwriters Laboratories Inc. (UL) when it is shipped from the factory.

3.4 Power Supply Safety

Note that even if the power switch is turned off, the current still flows to the primary side of the power supply unit.

Unplug the power cord before disassembling and reassembling the printer.

CHAPTER 1 PRODUCT INFORMATION

5.3.3 EP-87 Toner cartridge

Toner replacement mode

This printer utilizes toner replacement mode to make EP-87 toner cartridge replacement smooth.

This function detects toner cartridge presence when the power is turned on or the top cover is closed. If not all of the cartridges are installed, the developing rotary automatically rotates that the compartment of a missing toner cartridge comes to the installation slot. If two or more cartridges are not installed, close the top cover after each installation so that the rotary will rotate for the next missing cartridge. Detection and installation of the toner cartridges are conducted in order of Y, M, C, and Bk.

A message will be indicated to prompt replacement when the toner cartridge reaches the end of its life. Hold down the Replace Toner key found in the machine's upper left for 1 sec or more to move the cartridge to its position of replacement.

1)Insert the power cord and grounding cord to the printer and outlet. Be sure to use the supplied power cord.

2)Turn on the printer.

3)Remove the toner cartridge out of its protective bag.

4)Hold the cartridge as shown below and slowly rock it up and down five or six times to distribute toner evenly.

5.4 Notes for Storing and Handling the EP-87 Drum Cartridge and EP-87 Toner Cartridge

The drum cartridge and toner cartridge scan be affected by the environment and change over time whether they are still sealed in the box or installed in the printer, regardless of the number of prints. Since the pace at which it changes depends on installation and storage environments, be very careful in storing and handling them.

5.4.1 Storing the sealed cartridges

When storing in a warehouse or workshop (service depot), store in a specified installation environment. Note the following also:

1)Avoid areas exposed to sunlight.

2)Avoid areas that are subject to vibration.

3)Do not bump or drop it.

CANON LBP-2410 REV.0 FEB. 2003

CHAPTER 1 PRODUCT INFORMATION

5.4.2 Storing the unsealed cartridges

A drum cartridge contains a photosensitive drum coated with an organic photoconductor (OPC) that deteriorates when exposed to strong light. A toner cartridge contains toner. Advise the customer correct storing and handling of the cartridges.

a. Storage precautions

1)Store the cartridge always in its protection bag.

2)Avoid areas exposed to sunlight or near windows. Do not leave a cartridge in a car for a long time, as the inside of the car can get extremely hot.

3)Avoid areas that get extremely hot and humid or extremely cold and dry. Also, avoid areas where the temperature can change suddenly.

4)Avoid a salty air environment or areas exposed to corrosive gases, such as aerosols.

5)Store the cartridge in the temperature range 0 to 35 °C.

6)Keep cartridges away from computer CRT displays, disk drives, and floppy disks.

7)Keep the cartridge out of reach of children.

b. Handling precautions

1)Before installing a new toner cartridge in the printer, distribute the toner evenly as shown in F01-503-04. Rocking it any other way may result in toner leaking from the

developing cylinder.

After installing a new cartridge, print three to five test patterns to check for toner leakage to avoid image defects.

2)Before transporting the printer, remove all the cartridges.

Place the removed cartridges in their protection bag to avoid exposing them to light.

3)Do not expose all the cartridges to sunlight or strong light, since they are sensitive to light. Otherwise, it may result in image defects.

4)Do not touch or scratch the surface of the photosensitive drum.

5)Do not stand all the cartridges on end or turn them upside down. Labeled side of the cartridges should be facing up always.

6)Do not attempt to disassemble any cartridges.

7)Do not touch the waste toner detection window on the drum cartridge.

The photosensitive drum is protected by the protective shutter as blank spots or black lines may appear on the prints if the drum is exposed to strong light. Therefore, avoid opening the shutter. (The protective shutter opens automatically when the EP-87 drum cartridge is installed in the printer.)

11) Do not touch the light guide and electrical contact of the toner cartridge.
