Canon ira 5030i E20-0391

[Lasersupplies]

Hi,

i have a few canon 5030is throwing this message up recently. I blame it on a bad batch of toners that were bought in, my question is this, can this be fixed without replacing the Developer units in these devices as they are relatively new.
I can see that the DENS -C is around 8.5 on one device and 6.0 on the other. Does anyone know how i can lower these values or possibly fix the issue without buying replacement Dev units.

Thanks in advance

Hi,

If E20-0391 error, you can try as follows:

1. Check toner leak from the Toner Buffer Unit.
2. Check toner level in the Toner Container.
3. Replace the Developing Assembly.
4. Check short-circuit of the harness with the Toner Buffer Supply Sensor (PS3).

Make sure the harness that plugs into dev is ok. I have had issues with them(dry out and short,etc). On new machines....not sure. Make sure newest firmware is installed
