Iam getting p21 error what can i do?

Sir/ Mam,

The P- codes in general are giving you a heads up that something is going to go soon. Most time you can live with them.This code deals with the registration of colors on the transfer belt. The belt put image on the paper and rides above the drums shine item when you open the right side door paper goes between it and the sponge looking roller.Registration is like cyan on top of magenta for purple if not you get to see both colors. Any way to get to the sensors that monitor registration requires removing the transfer belt then opening the sensor covers to expose the sensors and clean them NO LIQUIDS. Mite want a tech to come out and do this

Color registration off

on the control panel, select "additional functions", then press "2" and "8" at the same time, and then press "additional functions" again. You should see a white screen with the words, copier, feeder, etc. Press "additional fuctions" and then press the "2" key. This will take you into level 2 of service mode. On the screen, select "copier", then "function", then "clear", and then select "reg clear", and then press "ok" in the lower left of the touchscreen. Press "reset" multiple times to get back out of service mode. Turn the machine off, and then back on. Press additional functions and go to "adjustment and maintenance". Select "auto gradation" and perform a "quick" adjust, and then a "full" adjust. This should bring your registration back. If you keep experiencing the problem, the secondary transfer roller located just before the fixing assy/fuser unit on the left side drawer that pulls out could have build-up in the bushings, or the transfer belt and drive rollers could be causing the problem too. Hope this helps.

My Rico Aficio 200

Please open the front door and turn the blue lever in the middle,
remove the Transfer and Separation unit and check if the bushings of the transfer roller are damaged.
If OK, please give some oil on the shaft/bushings of the transfer roller. This unit may be replaced as a whole unit.
If SC401 re-occurs, please check the Photoconductor unit (drum).

With my experience, it's not the registration nor calibration problem, it's either transfer belt is bad or inside the transfer belt is dirty or dusty as well as transfer rollers. here is what I do first
take the transfer belt unit out of the machine, take transfer belt out from the unit, clean inside of transfer belt with damp cloth and rubbing alch. clean all rollers and reinstall.
What it is if the transfer belt and transfer rollers are dirty and dusty, it slips and make it like it's not align. I think most of time it fix the problem with my exp. if not replace new transfer belt
