    [Jamming] Pro 400 Color M451nw

    Stops at exit , just out of fuser , as if it never arrived at the sensor . Very low print count on unit . FW 20130815 . Press start for reports , service page , feeds as noted above and then says " Jam in printer paper path open rear door and clear jam" , do this , then resets fine . Is there a self diagnostic or a service mode to check sensors ? I have a service manual , not finding it there . Or if someone has seen this occur , any other thoughts ? Thanks in advance , Ark .

      morer than likely you have the REPAIR MANUAL not the service.. there should be a diagnostic menu... you might want to run the alienation test

          Nope , only a service manual for this one ,I do know that in some cases there are TM ( Troubleshooting Manuals) and RM (Repair Manuals) But as far as i know , only a service manual for this one .

              there IS a RM.... it doesn't have any real troubleshooting or error codes in it

                      Check Liberty Parts web site, they have all/most HP manuals and parts/diagrams, free for downloading.

                          Like the OP said......no separate Troubleshooting and Repair manuals. Only a Service manual which covers both topics. These models do not have diagnostics. To low-end. How does the pickup roller look? We replace these rollers ALL THE TIME. They don't seem to hold up very well.
