I have an error code 990 and it will not clear - do you have any solutions?
You can try pulling out and reseating the Waste Ink tank which is located behind the machine behind a plastic door cover (left side of machine as you are looking at it from behind). Turn the machine off and on using the main power switch. If the code comes back then you will more than likely need a new Waste Ink Tank.
Installed a new waste ink tank but still receiving error that waste ink tank is full on a Ricoh GX3000. What do I do???
I have a Ricoh GX3000 and it is reading waste ink full after I have replace the waste ink tank. how can I fix this?
I believe there is an optical sensor in the front of the waste ink tank that can easily identify the ink pad as full when it's not even close to full. See if you can remove the sealed top from the waste ink tank and make sure the sensor can never be blocked. Just be sure to occassionally check the tank to clean when actually full.
