Hi ....

Ongoing problems with error code C-2557 on a C554e.
We have changed the K dev unit and K toner, but still got the code ( intermittantly )
Vacuumed out the hopper and visually checked all the workings within it.
We are taking a motor and sensor off of a C224e today to take up for testing.

Anyone experienced this on the C554e?

Thanks,

Guy

There is a mod bulletin for the c224e regarding this issue. I believe it will be the same for 554. You need to change the bushing.

We had this problem on a 224e. Forced toner, code went for a day, then replaced the dev, code went for a week. Turns out a plug was loose. If you remove the output tray, there is a sensor on the black dev, check it.

I had a new install of a c454e do this. After trying everything for 3 weeks I found a bulletin on the issue I was having. The paddle inside the sub hopper is not moving correctly against the sensor so the unit does not add toner to dev unit. There are cut-in serial numbers for the other models but not the c454e series. I ordered the sub hopper assembly and have not heard from them in 2 weeks.

I am not logged in but search for c255x in the bulletins if you have access to KM.

Replace the hopper assy. Have never had a developer unit go bad on one of these. Its always the dang hopper.

We have replaced the motor and p.i sensor for K. So far, so good.
