Hi, pel40169, if you installed a new cartridges in your epson printer, it must work. But in your case, maybe you leave your printer for a long period of time(couple of months) with an empty ink. If you did, then the printer head may get clogged which cause the print out doesn't appear.
Here is a better advice: If your printer get an empty cartridge, you must replace it with a new one immediately to avoid ink clog. It's better that you have a spare cartridge as reserve.
You may try to clean your printer using the cleaning feature of your printer by following this instructions:
- Open "Printers and Faxes". (Start>Control Panel>Printers and Faxes)
- Right click the model of your printer
- Select "Printing Preferences"
- Go to "Maintenance" Tab
- Select "Head Cleaning"
Do it only twice then print a nozzle check. If the problem persist, you can bring it to the store where you bought the new cartridge to know your problem. And if it's under warranty, you can bring it where you bought your printer for them to fix it for you. If it's not, you can ask for a printer technician, you can easily find a printer technician in ink refilling centers.
Hope this could help you.
