error! what error?

[jiro]

Recently when cleaning the printer it would give me a check wastetank display.The bottle was fine, so cleaned the sensor but that did not stop the display. Now it's giving me a fullwasteinktank error. Sound like I have to replace the sensor under the bottle, any other thoughts of what it could be.
thanks...

We had something similar, recently. Our waste tank wasn't anywhere near full, but something had clogged and set the sensor off. We by-passed it to get the job done, but afterward still couldn't find the clogged area at all. Jeremy sent some cleaner fluid through it and that didn't do a thing. We finally just took the can out, and found a slightly gelled area of ink along the tube. Blew it out and all is now fine.
