Black copies are great, but color is blurry. copytech..jpg

Looks like you have a problem with yellow registration. Try SP5-993-39 (Rough Line Positioning Adjustment) for adjustments more than 1.4 mm and then SP5-993-2 (Normal Line Positioning Adjustment). If that doesn't work, replace the yellow development unit.

Both those adjustments said "Failed", however the copies improved alot, go figure! I had already replaced the yellow dv unit before with no change. Also a curious thing with this machine, at first there were dirty bands across the pages, so I blew out the cleaning unit and they went away. But after only about 50 copies made during the process of fixing this other problem, the bands came back and when I pulled the unit it is filled with toner again. Is that a sign of another problem? My experience is mainly with Canon so I'm not very familiar with this Ricoh model. Your help is really appreciated.

You shouls clean the I D sensors and the transfer belt position sensor. then do the line adjustments.

Replace the cleaning unit and, like CrapAimer said, clean the id-sensors

Turn off Process control SP 5993-1 and then manually adjust the registration using 5993 10-15, once the registration is done it should be good
