If your Canon printer is printing blank pages, it could be due to several reasons. Common causes include low or empty ink cartridges, clogged print heads, or incorrect paper settings. Additionally, outdated or corrupted printer drivers might lead to this issue. To resolve it, check the ink levels and replace cartridges if necessary, clean the print heads using the printer’s maintenance settings, and ensure that the paper size and type are correctly set in the printer preferences. If the problem persists, updating or reinstalling the printer drivers might help restore normal printing.
