Misfeed and cleanning error for CM2320 printer


Q:  What is the problem for Misfeed and Cleanning error?
Ans:  This error is because of Misfeed. The printer detect that paper which is select for printing is moving too slow or too fast and the print is not properly printed on paper, some part of print is printed on
transfer belt thats why printer cleanning cycle run after every one or two paper.

Solution:
   Change the Tray 2 paper feed roller and sapration pad of printer.


1).Raise the printer to gain access to the roller. Use the side frame for lifting the printer. Do not raise the printer using the front door or the paper tray area.
 
2). There are two locking tabs that hold the roller in place. Use your fingers to remove or snap ring pliers. Remove the paper pick up roller.
        
3).Release the two cover locking pins and remove the separation roller cover by rotating down.
4).Release the separation roller locking pins and remove the roller.  Reinstall the roller cover on the locking pin and rotate it towards the roller until it snaps into place.



5).To remove the tray 1 pickup roller it will need to be lowered by pushing down on both ends of the assembly.
6).Release the two locking tabs and rotate the roller away from the printer.
7).Replace the separation pad for tray 1 by releasing the retaining tabs. The base that holds the pad will be loose when the pad is removed. There is a spring that can fall out.
8).To replace the automatic document feeder rollers open the ADF cover and release the spring that is attached to the end of the pick roller assembly.
9). Lift up on the pickup assembly and slide it towards the front of the printer to remove.



Remark: Many sites and blog suggest paper setting from jetadmin or hp tool box but nothing help me.
