Epson printer prints with horizontal white bands or streaks

If the printer hasn´t been used for a while this can happen.
The first thing to try is to run a head clean from the printers properties box and go to the maintenance tab, run various cleans and print a few pages until the printing improves(note this uses quite a bit of ink so you might have to get a refill).
If after many prints the print output is the same then you should try replacing the culprit cartridge.

PS: Sometimes if you get this printing problem after changing a cartridge it could also be a faulty cartridge.
