C454e constantly jamming

Re: C454e constantly jamming

Some halftone pages would be a great help here, but since you are also struggling with a jamming issue, get that resolved and then get the halftones. While the fade issue you are seeing can be caused by any number of issues, there are a few that can be the result of a dirty PH (Print Head) unit, also know as the laser unit in some circles.

Not sure what you've tried so far to remedy the fading, but the first step should be to try and clean the laser glass. There should be a cleaning wand attached to the inside front access door of the copier. Another possibility involving the laser unit is dust on the mirror motor inside the unit. On the Cxx4e models, the polygon mirror motor sometimes collects a layer of dust on the tips (corners) of the mirrors that write to the top (rear) edge of the drums resulting in a lighter, faded looking image. Fixing this requires removing the laser unit from the copier and carefully dismantling it, removing the mirror motor and very carefully cleaning off the mirror surfaces. Looking closely at the corners, the dust should be obvious if that is what's causing your problem.

Can't describe it any better, looks like you're reading my thoughts
