After many years of hesitating, finally I’ve decided to install the Continuous Ink System (CIS) onto my HP Officejet 6310 All-in-One printer. One of the reason for refusing to use CIS is the possibly of voiding the warranty due to third party ink, this is not a issue anymore because I’ve been using my HP for more than a year, the warranty expired last month.
One word to describe the CIS – awesome. The quality is not as good as the original, but acceptable because most of my prints are for review purposes, not for the final product to be archived. Benefits of using CIS:
- Cheaper and save cost
- Never run short of ink, you’ll always know the ink level
- Print quality is acceptable
My advice is – don’t waste money on original hp printer 22, 74, 88 and 95 black ink cartridges, they are not worth it.

What is continuous ink system? A continuous ink supply system feeds ink cartridges by way of silicone tubing. Continuous ink tanks designs vary, most incorporate a constant level, barometric pressure design. Constant level CIS delivers a smooth flow of ink to the cartridges as needed. Front tank is vented to atmosphere, negative air pressure in the back tank delivers ink to the cartridges.
Will CIS Cloak My Printer’s Print Head
The situation depends on your usage, if you are a frequent user, this should not be a problem. It is unlikely for the imitation ink to caked on the print head if the printer is used often. For small business offices, this is not much of a problem as oppose to home user with print frequency of once a month or less.
The other point to note is that it is a well known fact that refilled ink cartridge tend to be of lower quality. Based on my own experience, the colour will fade in less than a year, sometimes months and it smears easily if we hold the paper for too long.
Continuous Ink System Vs Self Refilled Cartridge
Back in the old days it was easier to refill a cartridge, things changed when the printer manufacturers decided to stop this refilling habit by using a new ink technology, which is to introduce ‘pressure’ into the ink cartridge. Newer cartridge are manufactured in such a way that it comes with a certain pressure, this enabled a faster and better printer quality minus the ability to refill the cartridge at home.
Have you ever noticed that ink cartridge refilled by ourself with those kits tend to leak, this creates a messy situation, eventually killing off the printer as the ink caked the print nozzle.

A continuous ink system (CIS), also known as continuous flow system (CFS), or bulk feed ink system, is a cost-effective replacement for ink-jet printer cartridges. In contrast to conventional cartridges, a CIS/CFS uses very large (about 100ml/color) ink tanks, which are connected with tubes to the printhead nozzles. The tanks can be refilled from an ink bottle or sometimes a syringe. Many CIS systems have been developed to cover most Epson, HP, Canon, and other printers.
These bulk feed systems also allow users to use inexpensive aftermarket inkjet inks as well as specialty inks for T-Shirt transfers or Black and White inks for B&W printing. These options have allowed users to produce specialty prints at a fraction of the cost of purchasing special cartridges or using more expensive printing solutions.

You may not have heard about this but there are some useful software that helps you to reduce ink usage, based on experiments, some allows a maximum saving rate of 75% and if you happened to be printing alot, this converts into a massive amount of money in the long run.
