Product: HP PAGEWIDE COLOR MFP P77940

Hi,

in my firm we have a HP PAGEWIDE COLOR MFP P77940. Some weeks ago we replaced Printhead Wiper Kit. Since that time, we had problem using the upper scanner (Automatic Paper Feeder)  when we want to scan some papers front and back (error 30.01.44). If we just want to scan front of papers, no error occurs. Furthermore, if we use the lower scanner (the one where is the glass) we can scan without any problem.

I upgraded the firmware, but the problem persists. Can you help me diagnose the problem?

Thanks
