Your inkjet printer's printouts all have a white streak down their whole length. What are the TWO things you can do to solve the problem?

Your print nozzles' ink has probably dried out, or if there is an obstruction inside the printer, such as a piece of sticky label, it might be preventing the ink from going where you want it on the paper. The nozzle cleaning routine would be the first thing to do, and you might need to do it several times. Look inside for something preventing the ink if the printout from the nozzle cleaning check appears to be good but the problem persists. Possibly, the ink cartridges need to be replaced. Inkjet printers don't use toner cartridges, therefore, using the wrong paper would result in different problems.
