When you buy a home printer, and pricey ink cartridges to put in it, you’ll want it to work without any hassle. So what should you do if you have problems with the ink cartridges? We’ve surveyed over 8,000 Which? members to find out more about the printers they use and the ink cartridges they top them up with. By crunching all this data we were able to uncover the three most common printer problems and how to fix them. Most printers work smoothly until they don’t. Printer frustrations don’t stop at paper jams. Blurry text, smudged or streaky images, and other ink issues can make a quick print job frustrating or downright impossible. In many cases, perhaps surprisingly, the issue is under-usage. When printers aren’t used regularly, the ink dries and the ink nozzles clog. To avoid these issues, print a test page once a week. If that doesn’t fix your issues, these troubleshooting tips will help get you back to clean, perfect printouts in no time.
