I think the F5 error is a fuser failure error. Check that the fuser is seated correctly in the printer. If the error does not come up all the time perhaps you can check the fuser is getting hot. If available perhaps try substituting the fuser for a replacement known good fuser to fully identify the fuser as the cause of the error
