Open the front door of the printer to access the roller. Spread the black plastic retainers on each side of the roller away from the roller (Fig. A.), then rotate the top of the roller off of the shaft and lift to remove it. Note the orientation of the roller, and install the new one in the same way. However, the separation pad (see next step) should be replaced before installing the new roller.

The paper stops just as it starts to come out of the fuser, and the printer display a paper jam error, but replacing fuser and ECU do not fix it.
The fact that the paper stops as it exits the fuser would seem to indicate a problem with the exit sensor in the fuser. Replacing the fuser is the normal solution, and in the rare cases where this didn’t fix it, the next suspect would be the ECU board (which reads the sensor). Checking the cables that connect the fuser to the ECU is the last sensible step. But we have seen cases where none of these things fixed this problem.
Strangely enough, you can often fix it by simply removing the formatter board, powering up without it, running an engine test, and then powering down and re-installing the formatter. We’re not sure what’s going on here – maybe a defective formatter, or maybe something just needed to be reset – but the significant thing is that it’s not any of the usual suspects. Note that in a normally functioning P3005, you will hear the printer speed up shortly after it starts to feed paper, as the fuser drive switches from the main motor to the fuser motor. We have noticed that the type of jam described above is often accompanied by a failure to go to the higher speed.
