your problem maybe caused by a thermistor near the pressure roll in the fusing unit (the red roll).
Try the follow procedure and if it doesn't fix call minolta service.
1. Turn OFF the Main Power Switch.
2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after
and check if the machine starts correctly.

HI there i have the same printer and for accurate color i follow this steps:
1 - First publicate you work in a pdf file whit high quality
2 - Go into adobe Acrobat (profesional not reader only) and pres print
3 - Then you have to select in advanced settings and select icc profile "sRGB ..."
4 - You´ll notice that the colors are very real. No oversaturated and the real deal are the fonts that prints correctly in border even if they are very small (- 6 pt.).
5 - RECOMENDATION: For intense black use a compost one 100% in every color or select in the color palette the one at the end of the palette
Greetins.

You'll need:
1- 1 compatible CompactFlash card (not all of them work, you'll need to try for yourself)
1- 1 CompactFlash card reader/writer
1- This tool
There should be a document enclosed with that tool explaining the process, it's fairly easy and quick. Notice that the procedure will solve some NVRAM related problems and also some network card related problems, but it will not erase your counters.
