Does Refill Toner Powder Work?

Refill toner powder is the practice of refill an empty laser printer toner cartridge with new toner. This allows the cartridge to be reused, saving the cost of a full new cartridge as well as the waste and disposal impact of an old cartridge.

While toner cartridges usually refill with good results, at least in some cases, refilling without being fully remanufactured can leave waste toner and paper dust from each print in the cartridge, which can cause background problems and contamination in the refilled cartridge.

Refill Method

There are several different ways to replenish ink cartridges:

End User Refill and Reuse: This is usually done by using a DIY Laser Toner Powder Refill Kit, which includes a supply of compatible toner, the reset chip needed, and instructions for the refill process. There are many types of toner, and many DIY toner refill products are available online from e-commerce suppliers or through specialty retailers.

Refilled and Resold by Original Manufacturer: Toner cartridges are often sold with a paid return label so they can be returned to the manufacturer for recycling and reuse.

Refill and resale by third parties: Many independent companies that sell toner cartridges refill and reuse original manufacturer cartridges, often obtained from recycling companies. This is generally considered legal if the original manufacturer’s brand is removed from the recycled product.

Refill Services: Many independent companies offer refill services, where customers bring in empty ink cartridges for refilling. Toner refill franchises have mushroomed over the past few years. Such replenishment chains offer customers the service of bringing in empty toner cartridges and refilling or replacing filled ones on site.

Toner Powder Remanufacturing: Similar to refill, except that not only new toner powder is added to the cartridge, but normally worn parts are inspected and replaced as needed.

Toner cartridges cannot be refilled indefinitely because mechanical parts such as rollers wear out. Some cassettes contain electro-optical drums, which wear out and can get scratched. Organizations that refill cartridges for resale typically clean and test each cartridge to ensure it is suitable for reuse and resale. While there are several sources for empty refillable inkjet cartridges, brand new empty OEM laser cartridges are not easy to find. Also, some models of laser print engines (like most inkjet printers) communicate with a “chip” or fuse inside the toner cartridge that it is empty, whether or not it is actually empty. It usually takes some research to determine the feasibility of refilling a particular cartridge.

Generally, DIY refills require opening a cartridge that was not designed to be opened, refilling it with toner, and then covering the opening. Some cartridges are removable; others require drilling or melting.

The composition of toner varies; manufacturers make toners designed for their own printers, and generic toners may not work as well. In some cases, toner powder and “developer” may be added separately. Supplemental kits include printer-specific instructions.

One supplier has identified the following basic types of replenishment toner (which vary mainly in particle size and fusing temperature), while other replenishment toner suppliers insist that each printer or copier model requires a unique type.

  1. HP, Canon printers
  2. Canon computer copier
  3. IBM/Lexmark Optra and similar
  4. Epson EPL, NEC Silentwriter
  5. xerox and sharp
  6. Samsung and Lexmark Optra E
  7. Brother
  8. Ricoh
  9. Konica Minolta

Kit replenishes 4 toner cartridges (cyan, magenta, yellow, and black) used with color printers, or refills a single toner cartridge. The kit includes a reset chip if necessary. In all cases, at least compatible toner must be used.

While refilling laser printer toner cartridges is good for the environment, refilled toner cartridges can produce poor print quality and reliability.

  1. Most printer manufacturers and toner remanufacturers claim that refilling ink cartridges by the end user or as a service compromises the quality and reliability of prints, ink cartridges, and the life of the printer.
  2. A life cycle assessment may show that recycling is a better option.
  3. The quality of third-party toner varies widely, and it is also important that the toner is suitable for a specific printer.

Frequently asked questions may include:

  1. Insufficient lubricant in the toner, causing damage to the drum, developing unit, or cleaning blade.
  2. The melting point is wrong, causing fouling of the fixing unit, printing content being wiped off, etc.
  3. Wrong electrostatic properties or particle size can result in dirty machines and poor print quality.
  4. A lot of loose toner in the machine can also cause dirt and mechanical damage, and the air filter can become clogged, causing overheating.

However, companies and individuals who refill toner powder say that, in most cases, the cost-effectiveness of refilling outweighs the possible disadvantages.

Security Considerations

As a fine powder, toner can be suspended in the air for a period of time and is thought to have health effects comparable to inert dust. It may be irritating to people with respiratory conditions such as asthma or bronchitis.

Toner is not toxic but needs to be handled with care because carbon black (one of its components) has been classified as a nuisance dust and has been designated as a probable carcinogen by the International Agency for Research on Cancer. Carbon black may contain known carcinogen impurities that may cause fine growths, eye irritation, headaches, itchy skin, and direct contact with toner can cause skin and eye irritation. Health and safety regulations must be considered when handling, transporting, and storing toner.

Safety precautions include the use of gloves and a dust mask to prevent inhalation. Toner spills can become charged and ignite if a standard vacuum is used to clean up, and the toner is so fine that it can pass through the filter and possibly escape into the room or into the vacuum motor.
