WHEN PRINTING BLACK AND WHITE DOCUMENT, HALF THE PAGE PRINTS FINE THEN BLOCKS OF WRITING ARE BARELY VISIBLE. THE BOTTOM HALF OF THE SENTENCE PRINTS BUT THE UPPER HALF DOES NOT LOOKS STREAKY.

You need the paper feed tires replaced.

Sounds like it's congealed ink on the print head. You can buy cleaning kits and do it your self. Relatively in expensive compared to leaving it into the shop.

It sounds like you need to run a printhead cleaning. The print head is what you put the ink cartridges into, it's responsible for placing ink directly to the page. If the some of the nozzles are clogged up, it can give you bad print quality. Without knowing the exact model of your printer, I can't tell you exactly where to find the menus needed to run the cleaning. Sometimes you can do this via the "maintenance" tab in the printers properties. If you need any further assistance, feel free to let me know.

it is problem your printer page setup please set defalt or re install printer driver
thanks

Are you useing vista print drivers for the vista computers or are they XP drivers?

If you are not using Epson ink, your printer will do this. Epson printers hate knock-off ink. Always use Epson ink if you want to keep your printer working properly. To solve the problem you are having, try cleaning the ink tubes. Make sure you re-install them properly. Hope this helps. Charlene

hmm..ok..can you run a test print page first to see how that looks?

try to do a system restore to a date when it was working ok, if still no go, then reinstall the printer driver.

some printers share the ink from color to black but you can select if you wants to use only black just go to printer than properies than select to use only black but you probably have to remove the empty color one

Try selecting an option in the printing properties to print in grayscale or black and white (you usually only have either one or the other). This will utilise ONLY the black cartridge, the color will remain dormant which should make your prints come out in black and white - if not, your black cartridge, or the space between the bottom of the black cartridge and the paper is contaminated with color ink. Good luck!
