You remove the PRINT HEAD????? DID YOU FOLLOW THE Service manual????????? Well you caused your own problem now you need to do a alignment. of the colors. you also might check the ribbon cable you removed and all the connectors you played with and check each one is secured. Recommend you don't ever remove the print head which houses the LASER unless you follow the service manual.

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
