How do you reseat the printhead for Canon portable printers?
Occasionally the print head may need to be removed or reseated to clear errors. To reseat the print head, power the printer on and open the printer cover. Press and hold the Resume/Cancel button for more than three seconds so that the printer ink tank will move right. Find the print head lock lever. Hold and lift the print head lock lever. Hold and slowly move the print head lock lever up and down several times. Lower the print head lock lever to lock the print head in place and close the print head cover.
