Actually, many time i found with seagate SATA power cable or PSU, and some 5 to 6 time in a span of 1 year i sent RMA to seagate, particularlly only with sata power cable problem.
boot in safe mode, uninstall the printer driver. restart.
boot normally into xp and while re-installing drivers select -search for drivers from net. OR get updated drivers from epson site which are digitally signed.
