Never ever do a memory clear all on a color unit. As you discovered it changes all the color registration values. This is a very, very complicated adjustment and very time consuming. I am a color expert and have been for 25 years now. Unless youre a trained tech youll never figure it out. spend 120 bucks and call a technician sorry..

Go to the printer's control panel, Print quality, Calibration, Calibrate now. Then print Configuration page from Reports menu. Look at the bottom colored stripes. If some of the colors is fading at the edges, your laser scanner usnit needs mirror cleaning. To get it out remove the back and side covers, then disconnect all wires to the electronics at the back. Remove the entire metal frame with the PC boards. There is the laser scanner unit - a black plastic box. Remove the screws and open it. The dust on the mirrors comes from the main fan next to the LSU. Remove the gratings (do not install back) and seal all vents with adhesive tape. This will not harm the printer.

One of our Ricoh CL3500N printers- less than a year old- gave us a "color regist error" after changing the transfer belt.
Ran the "adjust color regist" without results. It would just finish and pop back up with the same error.
Color test page printed no color, just BW
I reseated everything, and even replaced the PCU without positive results.
A couple hours later I went back, took everything out (be sure to keep the pcus out of the light!), and vaccuumed the heck outta that printer.
For whatever reason- maybe there was a chunk of toner hanging out, maybe I knocked something loose or back in place, whatever- but when I put all the parts in and turned it on, the error was gone and color printed great!
