I have an Epson SX600FW All In One Printer/Scanner/Copier/Fax new in October 2009. When I now print some of the words on lines are split horizontaly in the middle. This shows as a white line acros the full width of the paper. I have done a nozzle clean and a realighnment as per the instructions but it has not corrected the fault. I am using Epson ink cartridges and Internationa Basic A4 paper 80g/m3. Have checked the settings for the printer and these have not been altered since the original installation. I have Windows XP. No problem with scanning or fax.
