Safety Precautions

All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this product.

DANGER

Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.

1.Always disconnect the product from the power source and peripheral devices when servicing the product or performing maintenance.

2.When performing works described in this manual, do not connect to a power source until instructed to do so. Connecting to a power source causes high voltage in the power supply unit and some electronic components even if the product power switch is off. If you need to perform the work with the power cable connected to a power source, use extreme caution to avoid electrical shock.

WARNING

Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.

1.Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.

2.When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.

PRECAUTIONS

Strictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.

1.Repairs on Epson product should be performed only by an Epson certified repair technician.

2.No work should be performed on this product by persons unfamiliar with basic safety knowledge required for electrician.

3.The power rating of this product is indicated on the serial number/rating plate. Never connect this product to the power source whose voltages is different from the rated voltage.

4.Replace malfunctioning components only with those components provided or approved by Epson; introduction of second-source ICs or other non-approved components may damage the product and void any applicable Epson warranty.

Confidential

5.In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components.

6.Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several times. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads to completely absorb ink wasted due to the ink charge.

7.Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off with soap and water immediately. If you have a skin irritation, consult a doctor immediately.

8.When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts with sharp edges.

9.Use only recommended tools for disassembling, assembling or adjusting the printer.

10.Observe the specified torque when tightening screws.

11.Be extremely careful not to scratch or contaminate the following parts.

Nozzle plate of the print head

Gears

Rollers

LCD

Scanner Sensor

Exterior parts

12.Never use oil or grease other than those specified in this manual. Use of different types of oil or grease may damage the component or give bad influence on the printer function.

13.Apply the specified amount of grease described in this manual.

14.Make the specified adjustments when you disassemble the printer.

15.When cleaning this product, follow the procedure described in this manual.

16.When transporting the product with ink filled in the print head, take precautionary measure against ink leak before packing the product.

17.Make sure to install antivirus software in the computers used for the service support activities.

18.Keep the virus pattern file of antivirus software up-to-date.

Revision A

1.1 Product Summary

The features of this product are as follows:

Large capacity, yet compact

Large capacity

•Equipped with a large-capacity ink pack. This reduces the efforts required for managing and replacing consumables.

•Equipped with a large-capacity paper cassette. This reduces the frequency of replenishing paper.

•A maximum of 880 pages can be fed if an Optional Cassette Unit is attached.

Compact

•The installation area during use has been reduced by 14% as compared to the conventional model.

•The projection from the printer has been reduced by 85 mm as compared to the conventional model.

No need to wait due to high-speed processing

First printing is fast

•	Current model	Monochrome: 8 sec./Color: 8 sec
	→ This product	Monochrome: 4.8 sec./Color: 5.3 sec (single side)
 Printing speed is fast
•	Conventional model	Monochrome: 20 ipm/Color: 20 ipm
	→This product	Monochrome: 24 ipm/Color: 24 ipm (single side)
 ADF scan is fast
•	Conventional model	Monochrome: 19 ipm/Color: 19 ipm
	→This product	Monochrome: 22 ipm/Color: 22 ipm (single side)

High reliability reduces downtime

Reduced risk of paper jamming

•The paper feeding reliability is improved, and the risk of paper jamming is reduced by using a Retard Roller.

Defective pixels are not easily noticeable

•Equipped with a nozzle diagnosis system. The missing head nozzle is detected automatically and the image quality is adjusted, which helps secure the print quality, and prevents re-printing.

 Economy and ecology

 Low power consumption makes it an energy-saving product

•	TEC value 0.3 kWh
•	Power consumption during operation
	WF-C5790/WF-C5790a/WF-C5710/ET-8700:	Approx. 23W
	WF-C5210/WF-C5290/WF-C5290a:	Approx. 21W

 Improved transmission timing

The large-capacity ink pack reduces the disposed amount of consumables
