CISS printers are printers (common on Epson and cannon printers) modified to allow rapid refilling of ink cartridges. This is done by changing the ink cartridge into similar cartridge with rubber tubing attached to the top part; the tubing is connected to an external container that would supply the ink directly into the cartridges. The refilling process is not automatic. Once a cartridge goes empty, you have to manually press hold a small button (found directly above the cartridges) to allow the ink to run and do a refill. Since printers have specific ink requirement, you will be prompted about using genuine ink for that printer. Here’s the tricky part, sellers of CISS printers have found a way to override the ink requirement system so they could use different ink for the printer. This is a very bad thing. Printer manufacturer produces specific ink for a printer to insure good print quality and prevent blockage on the printer’s print nozzle.



                CISS printers are very handy if your printing needs involve a larger volume of printing. One good feature is you can print colored documents without the worry of running out of ink. If one of the cartridges run out while in the middle of printing your documents, you can follow the manual refill process and the printer will continue printing your documents when the refill is done. You could save a lot of money from using CISS printers than buying individual genuine ink cartridges. CISS printers also print at a fast rate than normal. There two ink types available for CISS use:

 water based ink – Water based inks have lower color quality and is easily gets washed up if liquid were ever to touch the surface of your printed documents. It cost much less than pigment type inks.


Pigment ink – Compared to water based, pigment have better color quality and does not fade and washed with liquid. I would suggest this type of ink so you wouldn’t have to worry about keeping your documents dry when you are traveling with them.


ConsWhy you shouldn’t buy CISS printers


  1. Shorter life span – think of it as pushing the machine to its limits. You will be asking the machine to print more, this will cause the printer to depreciate faster than expected especially the electrical components within.
  2. You will no longer be entitled to the warranty – Modifying the printer breaches the warranty agreement. So once your machine breaks down, it’s pretty much dead permanently. And it will be more expensive to repair your printer than to buy a new one.
  3. Increased chance of printer nozzle blockage – After the first few months you might notice that some of the colors are not produced correctly. In a print test you’ll sell that some of the ink colors (CMYK) are not printing at all. This could be due to a blockage in the printer nozzle. Printer nozzles have very fine holes, about a fraction of hair. These holes can easily get blocked especially if you stop using the printer for a week.
