I have also had same problem.
Bought Epson600FX 14 months ago and had no problems until replaced black ink T1001 cartridge. Very patchy at first in black and white and the nothing.
Contact Epson Support by E-chat and advised to take to Epson Repair Centre as looks like print head failure for which I will be charged.
Seems that this printer is one of the worst you can buy and I will definately be going back to HP. Not impressed that printer that cost £100 only lasted 14months and that what is obviously a poor quality designed and produced product does not have an adequate warantee from Epson.
Also very annoyed that I have just paid out £50 for a full set of Epson Ink Cartridges which might as well be chucked in the bin.
Thank you Epson for a load of expensive rubbish that wont even print on transparencies
