If your printer is running out of ink more quickly than you expected, it may be because you print a lot of images or text with minimal spacing. Printer cartridges are manufactured to print a minimum number of pages known as the page yield, and most page yields are calculated with an assumption of 5 percent ink coverage on each printed sheet. If that’s not the issue, it may be that your printer needs to be cleaned to prevent the nozzles from clogging and drying out.
