First, check if you have removed the yellow plastic tag completely from the cartridge surface. If you have already removed the yellow tag, the problem might be that the presence of air bubbles around the print head while changing cartridges blocks inkjets. Poor color or white lines on printouts could be for the same reason. You may either proceed with the "Cleaning Print head" function in your printer for a couple of times to remove air bubbles, or, leave your cartridge inside the printer for an hour or so to let the bubbles rise to the top. (Please note: AVOID TAKING OUT THE CARTRIDGE FROM THE PRINTER ONCE INSTALLED.)

Some printer models have printout-counting system, to which the printer manufacturer has pre-set the limit of the printing volume of a cartridge. If a functioning cartridge is taken out of the printer and replaced with a new one, the printer will not reset itself but continue to add numbers to the previous count until the limit is met and "Ink Out" signal is on again. You can restart the printer and run the "Replacing an ink cartridge" process again. Do remember not to replace the cartridge until the printer signals "Ink Out" for the next time.

There are many different ways to save printer ink. Of course the best way is to use the compatible printer cartridges. Apart from this you can set your printer to print in draft mode until you are ready to print the final document. This can be done by setting two different print queues. You can also set up a print queue which prints in black and white only. This can save a lot of color ink. When you print page from the web, try to look if the website offers a printer friendly page with much lesser graphics.

No, this will ruin the cartridges. Please store them in a dry area that’s at room temperature.

Place the clogged cartridge in about 1/4 - 1/2 inch of warm water for a few minutes. When ink starts to slowly leak out take the cartridge out of the water and dry it using a soft cloth to "Q-tip." Then place it back in your printer and run the print head cleaning utility that comes with your printer software. You may have to run this 1-2 times before printing quality is re-established.
