The R320 is not compatible with the keypad press routine if I remember correctly so you really need a utility that can work with it.

I've had a quick check and found that the A10_IPR is capable of handling the reset for that model but for completeness here's the link for all the current info I have on the R320 in terms of resetting and fitting an external waste tank which you'll want to consider to avoid the printer flooding with waste ink.

Hope it's of some use but let me know if you're still borked after trying.

The Solution is simple: Unplug your printer then remove all the catridges then turn it on. Then the printer will display error indicating no catridges then put back the catridges then it will automatically reset your printer thats all folks...Please comment if it works for u...

I found this on another website and it worked for me. It apparently resets the printer. Hope it works for you:

1.) power on (error message)
2.) press the "Stop (triangle)" and the "Colour copy" button and hold them
3.) press the power button to power off, still hold 2.)
4.) press the power button to power on, still holding 2.)
5.) the LEDs start to flash, then they stop to flash and the red exclamation mark starts to flash. Now release 2.)

6.) the LED should say: "Init EEprom"
7.) now press and hold the power button until the printer powers off and powers on again.

TRY TO PRESS POWER BUTTON OR THE OTHER BUTTON FOR MORE THAN 10 TO 15 SECONDS THEN IT WILL BE RESET

Here is how to get the ink cartridges to move to the changing position on the R320.

1. Press the paper jam/ink button on the printer control panel.
2. A menu comes up. 1st item is ink cartridge replacement. Press
OK button.
3. Another menu with ink cartridge replacement. Press OK button.
4. Thats it, ink cartridges move to the changing position. Change your cartridge as you normally would and follow prompts on screen to finish process.

Hope this helps.
