HP Envy 4520 Prints Blank Pages
Ensure the document you intend to print does not have any blank pages. Open the access door located at the top of the HP Envy 4520 Setup printer. Lift the lid of the ink cartridge slots. Press the cartridges and take them out. Wipe the contacts of the cartridges using a lint-free cloth with distilled water. Leave the cartridges to dry for a few minutes. Insert the cartridges into the appropriate slots. Close the lid and access door of the printer. Perform a printer function and check if the problem is solved.
