If you`re refilling a standard cartridge, you can put in about 4ml of ink. If you`re refilling a high yield cartridge, you can put in about 10ml of ink.
Well, the answer to this question is – YES, the HP ink cartridges having a built-in printhead, can be well refilled. You can get refill kits for several popular HP ink cartridges, which include HP 60 and 61 series.
The amount of ink in a cartridge varies from 8 ml to 127 ml depending on your inkjet printer. Regular HP or Epson inkjet cartridges hold only a small volume of ink while ink tanks for CISS printers hold a higher capacity of ink.
Toner cartridges cannot be refilled indefinitely, because mechanical parts such as rollers wear out. Some cartridges include the electro-optical drum, which becomes depleted and can be scratched.
Laser printers use toner cartridges which print thousands of pages so you don`t need to worry about replacements anytime soon. Laser cartridges contain toner powder so you also don`t have to worry about the drama of running into dried or clogged ink at all!
How Many Pages per Ink Cartridge On Average You Can Print? How many pages can you print with one ink cartridge? According to PCMag, a standard ink cartridge will print an average of 220 pages, (with 11 ml of ink). A high capacity cartridge prints an average of 350 pages, (its tank holds 16 ml of ink).
Printing on 5% = 480 pages (the official page yield). Printing on 10% = 240 pages. Printing on 20% = 120 pages. Printing on 40% = 60 pages.
Cartridges are supposed to be able to be refilled at least twice before replacement.
Yes, in many cases you can refill ink cartridges. However, if the cartridge has dried ink inside it, don`t try refilling it as it will likely not work properly. For Inkjet printer cartridges, follow the step-by-step instructions explained above.
Ink cartridges can usually last two or three years if properly packaged and stored. But in a standard case, they will eventually dry out and become useless after this period. However, many major ink cartridge makers don`t put expiration dates on their cartridges.
A typical ink cartridge will yield 250 to 300 pages depending on the color density of the prints. The yield of a typical toner cartridge in a laser printer is between 2,500 and 3,000 pages. Some larger laser printers can even have toners that will yield up to 30,000 pages!
A typical toner cartridge will produce anywhere between 2,500 and 4,000 pages, based on a coverage of 5% (roughly third of a page of double-spaced text). Dense pages filled with small font text or graphics will dramatically reduce this output and you may only get up to 1,000 pages per cartridge.
As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.
Monthly print volumes for laser printers are well into the thousands for most models. However, most inkjets have a monthly duty cycle usually under 1000. If you`re looking to print fast and print a lot, laser printers are the way to go.

run with empty ink cartridge
ANSWER : The only way is to buy a chip resetter and reset the chip on the cartridge. You can find them online for about $5. You just hold it against the cartridge until the light turns green. You do run the risk of damaging the printhead due to overheating because of no ink in it.
