Canon MegaTank PIXMA G6020 is slow when printing

The checks in more detail

A large PDF with many images takes time to process before the printer starts, so a long wait followed by normal printing is a processing delay. Check the connection. A printer on weak Wi-Fi takes a long time to receive a job. Print a network settings page from the printer's menu and check the signal; move the printer or the router, or use a USB cable or Ethernet, if the model has the port, for a test. Check that the driver is Canon's and current, since a generic driver is slower and lacks options. Clear the print queue. A printer that was idle may run a cleaning or an alignment before printing, which takes a minute. The MegaTank's ink system matters too.

The G6020 has ink tanks that you refill, and low ink in a tank can cause the printer to slow to avoid air; keep the tanks above the lower line. Dried nozzles after long inactivity cause repeated cleaning cycles and slow starts, so print regularly. Check the firmware with Canon's update tool. If the printer remains slow with simple pages in standard quality over USB, contact Canon with the model and serial number, since a head or engine fault is possible. On the G6020, a slow print often comes from the quality and paper settings in the driver.

Standard and High quality on plain paper take longer than Draft or Fast, and a photo paper type makes the printer lay down more ink and move more slowly. Check that the document is not being sent as a very large image, and try printing a simple text page to see the printer's own speed. In the Canon PRINT app or the driver, make sure the print job is not set to Quiet mode, which deliberately slows the printer to reduce noise. Wi-Fi with a weak signal slows the transfer, so check the connection and try USB as a comparison. A printer that has not been used for some days may run a cleaning cycle first, which adds a delay. Update the driver from Canon's support page.
