When I'm printing a document the printer powers off then in about 30-60 seconds it powers back on. This will also happen if I'm not printing.

We had to open the rear door to remove a jammed paper - it now is jammed near the hinge - any ideas - we can't see anything it is hitting on but don't want to force it

I replaced the imaging unit in a clp-300 and did a firmware down load that was mentioned on a page included with the imaging unit
Now the text characters print with very thick lines like an exaggerated bold font

The problem occurs when printing from either computer

This printer has taken to jamming - not paper jams but some kind of mechanical jam. It warms up, the gears inside try to turn and then they stop and the light goes red. The only way to get it to work is to remove the toner cartridge tray and then reinsert it over and over. Eventually it will print, but then it jams again. Please advise.
