DIY Printer Fixing Guide
Hook a syringe up to the input tube and push cleaning solution through. If it flows all the way through into the waste tank, it's not clogged. If it doesn't push through, you need to unclog it. Other than that, all you can do is watch the waste tube to see if ink is flowing through when it does a cleaning cycle. If ink flows out the waste tube, the pump is most likely still good. If no ink flows, it could mean the pump is broken but it could also be other ink flow issues such as bad cap tops. Out of the ~100 Rolands I have worked on, I have never had a new style pump go bad. The old style go bad after about 2 years of use usually.
I'm not sure what printer or pump you have, but be careful not to push the syringe too hard.
If its like my pump, when the rollers that push/pump on the pipe are in a certain position you wont be able to push, as the rollers will block it. only when it backs of in reverse and it releases the rollers from the pipe can you push fluid through.
Did you try removing the black pipe going in to the pump, running a powerful clean and feeling with your finger for any suction? or popping the end of the pipe in cleaning solution and seeing if anything pulls through in to the drain bottle.
I had concerns mine wasn't working, as it wasn't filling the drain bottle.
It was ether already broken or I broke it pushing to hard testing it, similar to VanderJ test.
Mine had resistance then as the rollers moved (motor) and I pushed I had no resistance, the tube had split, and I had a lovely leak out of the bottom of the pump.
I have replaced my internal pump pipe, but with a pipe not as soft as the original, it turns sometimes but just makes a noise, vibrates and doesn't move for a while. I m currently waiting for a new one.
Does anyone know if bleeding them helps? did you also look if anything was dripping in to your drain bottle while doing a powerful clean?

Hey zigns62,
The other team members have provided some wonderful troubleshooting suggestions, but remember, if it gets to be too much to handle, just call your regional Roland dealer and have the printer repaired by them (something to consider).
