OEM is "Original Equipment Manufacturer". OEM cartridges are referred to cartridges bearing the same brand names of the printers, such as Epson OEM, Canon OEM, HP OEM, Lexmark OEM, Brother OEM and others. These manufacturers are certified by Epson, Canon, HP, Lexmark, Brother and others. Except for OEM ink cartridge, there are also compatible and remanufactured ink cartridges in our store.

Hello Eco’s compatible cartridges are designed to be the economical replacements for your OEM (Original Equipment Manufacturer) inkjet cartridges. Our compatible cartridges are manufactured by a highly qualified (ISO 9001 certified) and respected manufacturer with strict quality control and innovative technology.

Remanufactured cartridges are manufactured from recycled empties after disassembling, inspecting, cleaning, reassembling, refilling, and testing. All our products are manufactured to meet or exceed the specifications and high-quality standards of OEM products.

There are a lot of reasons for using compatible, remanufactured cartridges or refills. You can enjoy huge savings on printer consumables while getting similar or the same results. Also by using remanufactured cartridges or refills, you help protect the environment. The key issue is to find a reliable supplier like us with high-quality products and supreme customer service to stand behind our products. Our products are safe to your printer. By choosing our products, you get best values - low prices but high quality products and most important of all, excellent customer services.

No, the use of compatible, remanufactured cartridges or refills will not void the warrant of you printer. It is stipulated in "MAGNUSON-MOSS WARRANTY IMPROVEMENT ACT" passed by the US Congress. MAGNUSON-MOSS WARRANTY IMPROVEMENT ACT United States Code Annotated Title 15 Commerce and Trade Chapter 50 Consumer Product Warranties 15 Section 2302 (c)

No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name; except that the prohibition of this subsection be waived by the commission if:

1) The warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and 2) The Commission finds that such a waiver is in the public interest.

The print head is the most critical component in an inkjet printer - it is used to deliver the ink cartridge to the page that you are printing. Most desktop inkjet printers use cartridges that come with the print head attached; a few printers have separate print heads next to which the ink cartridge is inserted. Please don't touch the print head with your fingers. The print head is a consumable that can wear out over time, much like the brakes on your car. It requires proper installation and ongoing maintenance to ensure the long life of service for your printer. Most print quality problems come from a direct result of improper care of the print head. Proper installation, ongoing attention and maintenance are the keys to prolonging the life of your print head.

No, there is no evidence that suggests our cartridges will damage your print head. Print heads are not durable components; they will wear and tear over time. The life of your print head will depend heavily on how frequently you print.

Overtime, a print head will require maintenance in order to sustain the printout's quality. A cleaning cartridge contains cleaning solutions which help clear the print head in the cases where normal head cleaning is not sufficient. A single cleaning cartridge can usually be reused multiple times. This helps significantly on extending the life of your printer's print head. Our cleaning cartridge is well designed for cleaning print heads and priming print cartridges for refill, allows print heads to soak the printhead cleaner to refresh the print nozzles and help restore print quality.

Dye ink uses water-soluble dye and pigment ink uses water-insoluble particles to deliver color to the paper. There a few major differences between inks that are dye-based and pigment-based. Epson's patented Durabrite is a pigment-based ink formula. Pigment based ink are much more resistant toward water stains and sunlight. Dye based printouts will become fazed by water stains, where pigment based printout would not be effected. Pigment-based ink printouts may withstand direct sunlight exposure for years, while dye-based printouts may last half to one year before noticeable fading happens. Dye based ink do have a wider color gamut compared to pigment based ink. Some people find printouts using dye based ink have more vibrancy.

The circuitry that is seen on some cartridges (such as some HP or Lexmark Cartridges) is the ink delivery system or print head. This mechanism is a system of nozzles that are used to push ink onto the paper.

Nozzles, or "jets" are located on the print head. There may be anywhere from 48 to 320 nozzles on any print head, and each of them is smaller than human hair. Each nozzle is connected electronically to a heater (resistor) that actually heats and cools the ink inside the cartridge. When the ink is head, a bubble is formed. When the heat is removed, the bubble bursts and sends dots of ink through the nozzles and onto the paper in the printer. This happens very quickly, creating dots that form print characters on the page at a rate of up to 6,000 drops per second. That is why you should never touch the nozzle or print head assembly with your fingers.

Yes, we sell a lot of compatible ink cartridges with smart chips. The chips are already installed in the cartridges and you don't have to pay extra money to get them. Neither do you have to buy separate tool set to install the cartridges. (CAUTION: DON'T TOUCH THE CHIP BY HANDS. READ INSTRUCTIONS ENCLOSED BEFORE INSTALLING THE CARTRIDGE.)
