This is probably due to miss alignment, there is an option of test page which will be scanned to allign the cartridge, if ur's a all in one printer. This test page is printed at the first time and scanned instantly for first time operation.

Thankyou

See Craig Gillette's answer from Feb21,2010. That's your problem too.

If an inkjet printer gives white streaks where it should be black, it means the ink is very low, or there is dirt under the nozzles preventing it from printing properly, or, in the case of non original cartridges, ink might be leaking which prevents the bubbles of ink to squirt onto the page.

If the streaks are black where it should be white, is sounds like some dust or fluff below the cartridge leaves ink smears on the page.

It's not the cartridges, the waste ink is coming up thru the bottom to the exit rollers. The only fix is to have a shop open it up, clean up the ink mess and install a shield that stops the ink from coming back up when it should go to the absorbers. The new machines all have this shield and the ink tube cut back to make the ink go where it should.

Thoroughly clean all the ink residue from around the ink cartridges, some ink is sprayed every time you print.

make sure the bottom of the print cartridge is clean. If not tak etape and then tape it off if theres too much ink leakin on the cartridge.

For some reason, the printer is designed to dump ink into the bottom of the tray before feeding on the paper. The paper is then dragged over the ink, leaving the black line. This is a software issue, not a hardware one. I'd advise that you update all of your print drivers, as well as your firmware.

A temporary fix is to clean the rollers and base plate of the printer for ink spills.

Check for any bits of paper or debris that may be caught in the printer. Be careful to feed in the paper perfectly straight, as this printer does not have good rollers, and it will cause paper to break off and cause problems. If any debris has caught or absorbed ink, it will cause the back of the paper to smudge, and you have black lines.

Hi, like every ink jet printer, there should be an ink pad(spunch) at the bottom of the printer to collect the waste. That spunch might be full of ink. You could locate it, remove and try to clean it under the water. See if it works

HI Foster,
The problem is not with the print head. Print a blank page and if you are still getting the streak. Something is probably trapped in the printer or the rollers are dirty.
