We have a HP Laserjet 4m+. It randomly gives us an error code of 41.3 right in the middle or at the end of printing a document. It is not page specific. However when the error code pop’s up, once we clear the message it starts printing codes instead of what it is supposed to print. The suggestions I got from HP’s website and the manual did not help. I even replaced the pick-up rollers and that did not work. Any advice would greatly be appreciated. Thank you in advance.
