Where is all of that valuable ink going?
The ink outlet holes on the print head's surface are many times smaller than the diameter of a human hair and because of this they can become blocked or 'clogged' very easily. The inkjet printer has a sponge running the whole width of the print head track (underneath the print head) so when you hear your printer racing back and forth when you are not printing it is actually cleaning itself.The printer is actually squirting your valuable ink through these microscopic nozzles to try and keep them clean. From there it gets pushed out of these small nozzles onto the sponge as it cleans the print head surface. As the sponge gets filled up the ink gets deposited into the waste container underneath the sponge. Anyhow take a look at the video below and see for yourself where all of your valuable ink is going.
Now that you've seen where a large amount of your expensive ink is going you may like to have a read of this article: Why do ink cartridges cost so much. Very interesting to read that 80% of most printer companies profit comes from consumables !
Can you reduce the amount of ink your printer consumes?
Fortunately with most of the common Inkjet Printers the answer is YES ! Remember that ALL Inkjet Printers are designed to do a Print Head clean every so many times that they are turned ON. During this initial clean a massive amount of your valuable ink is consumed. The easiest way to avoid this happening is to simply leave your printer turned ON !
By leaving your printer turned ON you can reduce the amount of ink it consumes by up to 80% or more (depending on how much printing you do). The average Inkjet Printer will only consume around 6 - 10 watts of power when its in standby mode. This amount of power would add almost nothing onto your annual power bill. Compare this with the cost of ink which is consumed in a year by turning the printer ON and OFF each time it is used.
Factors that change ink usage
There are several other factors that can affect the amount of ink usage.1. Lowering the print quality or print resolution
