How can I get dried ink out of my inkjet print head so I can print again? What are nozzles? Where it is in printer? I want to get more technical information on inkjet printers, so I can easily solve minor problems and save my time as well as money.

Please help me with your replies to increase my basic technical knowledge in inkjet printer information.

Please let me know what is the shelf life of compatible brand ink cartridges? And which ink cartridges can be recycled?

Can I use the same ink for different cartridges? Is there such thing as universal ink?

I would not recommend using the same ink in all cartridge because they would have different thickness, chemicals etc.

The shelf life of a cartridge is anywhere from 6 months to 1 year, again it can vary depending on the brand.

If you open a cartridge I would recommend keeping it in a sealed ziploc if you are not gonna use it yet.

The inkjet technology varies depending on the company:

Some have integrated printerheads that you change everytime you change cartridge (a few years ago HP was using this technology, im not sure if its still the case)
Some other companies have printheads as consumables (canon had that a while ago, it might not be the case anymore)
Some other companies have the printheads integrated in the printer and you dont need to change them unless they get damaged.

To get a better idea you should check on each companys website.
Most cartridges can be recycled at your local office store, some cartridges are made of 100% plastic and can be recycled in the bin.

Your questions are very vague so its hard to give you specific anwers :grin:

Thanks for giving your precious time to give detail information. I personally appreciate your help. I have also find out one website from where I got the information on use of "OEM Matched" products. They provide "OEM Matched" products for Epson Printer Ink Cartridges, Hp Inkjet Cartridges and Canon Printer Ink Cartridges. But your reply is what I am exactly looking for.

Again Thank you very muchEpson Printer Ink Cartridges for your reply.

Be careful when using generic ink. I know its much cheaper but sometimes it actually is too good to be true and you can cause serious damage. Ask them about warranties, will they replace your printer if the ink damages the printheads, etc.

One ink cartridges, you can see 2 parts on it, the copper contacts/electrical contacts which helps the printer to detect the cartridge, detect the part number, expiry date and the number of the cartridge on which printer model it is intended to use. The nozzles is the one who spits out the inks, that would be under the cartridge. Nozzles have very sensitive and tiny holes where the inks come out and it cannot be seen on our naked eye, by touching it, it will clog the inks and will likely give you a print quality problem or damage the cartridge. For cartridges, it has a Yield page, or how many pages it can print of course depending on how you use it, if you use a high quality printing or a draft mode printing. Most refilled ink cartridges usuallly have no expiry date, part number or expired expiry date on the cartridge itself, they may case spill of inks going to the copper contacts, causing a ink system failure/cartridges appeared to be missing or damage/ink cartridge error: those are some error messages with that specific problem on refilled inks and it will damage the printer contacts as well as voiding your printer warranty. If you want to use other ink cartridges to another printer, usually if it fits perfectly to another printer, it is not recommend to do that since cartridges has it's own electrical contacts that plays it part to detect the correct printer model although some will work but will damage the printer contacts in the long run. Other ink cartridges can be recycled in other printer brands (maybe), it depends on the quality of the ink that they are going to replace inside the cartridge. Hope I answered some of your querries. Let me know if you have any other questions so I can give you a quick answer. (If i have the answer) :)
