your print head is either clogged or damaged, A print head is the unit your ink cartriges sit in. If its a nedw or newer printer (under warranty) you can contact the manufacturer and they will send you a new print head at little to no cost-good luck

Calibrate your new blank ink cartridge, have some nozzle check, cleaning check, and printer alignment. This are procedure that new ink cartridge will have to calibrate before you use. Epson printer are very sensitive when capable of changing ink cartridge. Unlink HP directly work without any print test because the cartridge head and ink join together, Epson with ink cartridge and the head separate.
Have some test on it at Printer Maintenance.
I'm sure 100% works on it.
Good luck!

did you remember to pull the tape off the print head before you installed the new cartridge?

Here are all the flashing explanations:

Two flashes: Out of paper or paper feed error

Reload the paper correctly and press the RESUME/CANCEL button.

Three flashes: Paper jam

If paper has jammed in the printer, clear the jam, reload the paper in the printer correctly and press the RESUME/CANCEL button.

See Paper Jams

Four flashes: Empty ink tank

If you press the RESUME/CANCEL button, it will continue printing with an empty ink tank. After printing is finished, replace the ink tank immediately. If you continue printing with an empty ink tank, it may cause damage to your printer.

Refer to your Quick Start Guide for instructions on how to replace an ink tank.

Five flashes: No print head installed/Defective print head

Install the print head. Also, ensure that the protective tape has been removed.

If reinstalling the print head does not solve the problem, replace it with a new one. Contact the Customer Care Center.

Eight flashes: Waste ink tank almost full

The printer has a built-in waste ink tank for the ink used during print head cleaning. Eight flashes indicates that the waste ink tank is nearly full. Press the RESUME/CANCEL button to cancel the error so you can continue printing. Before the waste ink tank becomes completely full, contact the Customer Care Center.

You may have not used the printer for a while and even if you change ink cartridges, the printhead nozzle may still need a flush or cleaning. It is not too hard to do. Watch video of instructions and I think you will get the printer to print again:

Two flashes: Out of paper, paper jam or paper feed error
Replace the paper correctly and press the RESUME/CANCEL button.
If paper has jammed in the printer, clear the jam and press the RESUME/CANCEL
button.

Three flashes: Paper jam
If paper has jammed in the printer, clear the jam, replace the paper in the printer
correctly and press the RESUME/CANCEL button.

Four flashes: Empty ink tank
One of the ink tanks is empty. Replace it.

Six flashes: No print head installed
Install a print head.

Seven flashes: Defective print head
Remove and reinstall the print head.
Also, ensure that the protective tape has been removed. If reinstalling the print head
does not resolve the problem, replace it with a new one.

Eight flashes: Waste ink tank almost full
The printer has a built-in waste ink tank for the ink used during print head cleaning. Eight
flashes indicates that the waste ink tank is nearly full. Press the RESUME/CANCEL
button to cancel the error so you can continue printing. Before the waste ink tank
becomes completely full, contact a Canon service representative to have the waste ink
tank replaced. Canon recommends to call for service as soon as this error occurs. Once
the waste ink tank becomes completely full, printing will be no longer
possible.
