I was called out to work on a M1536DNF for a customer who informed me that while installing a new toner cartridge, part of the machine broke inside and then, after every print, the machine recorded a paper jam. If the customer opened and closed the toner door the machine would proceed to print another page then record a jam. Obviously this got old very quickly and the printer needed to be checked out. Upon arriving onsite I noticed the broken part was the delivery assembly. Unfortunately, this assembly is part of the fusing assembly so the whole fuser needs to be replaced if this part happens to break.
This machine ended up being under warranty so I called HP and got the machine exchanged. Usually when I call HP it takes about an hour of troubleshooting and another hour to setup the warranty service. This time, however, it didn’t take long as the customer rep on the other end was well aware of the issue.
This service information is more of a general tip to those of you in the field servicing these machines or planning on selling them. The delivery assembly is somewhat fragile and replacing the toner seems to lead to this part breaking. HP noted that this often happens when the customer fails to remove the shipping tabs. So whenever servicing these machines I will be informing my customers of this design flaw and warn them to handle this area with care in the future. If you do find yourself needing to replace the fuser outside of warranty, the part number is RM1-7576
