Question about Canon PIXMA iP4300 InkJet Photo Printer
Hold the resume/cancel button in until the LED blinks twice. This should print out a test page. Is the line still there? If no, try a different USB port, or reinstall your printer driver or try substituting your USB cable.
If yes, try this: open the lid, when the head moves to the center unplug the power. Remove all the ink, lift the lever on the head and remove the head. On the back of the head are small contacts. Make sure they are clean. You can use a soft cloth and a dab of windex on the cloth to gently clean the contacts on the head.
Inspect the bottom of the head. It may be pretty dirty with ink and other stuff (dust, hair, ashes). If it is, you can clean it but you must be very gentle. A good trick is to put some hot water in a saucer and set the head in the saucer for a few minutes. It's important to only get water on the bottom surface of the head (where the dirty ink is). After soaking, gently pat it dry with some paper towel or a soft cloth you don't mind getting dirty. Inspect it again. If you see any scratches on the bottom of the head it may be the cause of the problem. Reinstall the head in the printer and reinstall the ink cartridges. Plug it back in, turn the power on and retest it. If the printer still has the line, you may have a bad head. In a small number of cases this can also be caused by a bad board in the printer. If you decide it's definitely the printer after cleaning the head, you can either check if you have a local Canon service center or you can check into replacing it.
