Usually, Canon printer problems occur at the most inopportune moments. The printer could produce breathtakingly beautiful printout, when they are in good working order, but when you get a problem with your Canon printer, it can be very frustrating. The paper jams are the most common causes of printer problem. Your canon printers jam for any number of reasons, including dirt in the paper path, the wrong type of paper being used, or worn printer rollers. By keeping printer components clean you can prevent paper jam problems, but roller replacement may also be necessary, and this can be a difficult job. To detect problems earlier check ink levels of ink cartridges as they run out fast. You might be out of ink if your printer looks like it is printing but nothing comes out on the page.
