The Canon MX310 is an all-in-one office printer capable of printing, faxing, scanning and copying. Like most Canon printers, the MX310 has an ink cartridge monitoring system to estimate the amount of ink left in the cartridges. If you purchase refurbished ink cartridges, or if you have your ink cartridges refilled, you may receive "Low Ink" error messages even when you have sufficient ink to print. You can reset the Canon MX310 to clear the old ink level memory so the printer properly recognizes the replacement cartridges.
Switch the Canon MX310 off using the "Power" button, then push the "Stop/Reset" button on the control panel. Hold the button down for about five seconds.
