49.2c05 is a communication error. the 13.12 is a jam error. try upgrading the firmware with the duplexer not installed. firmware can be found at www.hp.com
You've done everything I would have done and more. How about you installing a DOA duplexer. At this point I would change it again. Is there another printer that you can swap duplexers with? There is a paper path sensor test (letter H) and manual sensor test . I don't know if the Component test checks the duplexer, but you should be able to find out. Is the printer still under warranty? Can you call HP or are you an HP tech and you can call 2nd level support. Just a thought....when you run a Config sheet, does it show the duplexer?
We went through this with a client and ate up 20 hours of diagnostics time. It started when we installed a new fuser under the HP service advisory regarding worn fuser bushings. We tried another new fuser and had the same issue. Eventually we rebuilt the old fuser with parts from the new one and it worked, it seems that the heating elements on some fusers had issues. HP tech support, including engineering support (level 2 and 3 escalations) was not able to solve this problem.
The document I was thinking of referred to fuser wrap jams. I did some quick checking of duplex jams though and this might give you some guidance to check for.
These errors refer to jams when repicking to print side 2.
Cause
Solution
The spring of the duplexing media-repickup-sensor lever is unhooked
Check the spring and place it in the correct position.
The duplexing media-repickup-sensor lever is damaged
Replace the duplexing feed unit.
Poor contact of the duplexing media-repickup-sensor connector
Reconnect the connectors of the duplexing media-repickup sensor (J1945), intermediate (J1909, J1950) and the DC controller PCA (J4105).
The duplexing media-repickup sensor is defective
Check the duplexing media-repickup sensor by the sensor monitor mode. If the sensor is defective, replace the duplexing feed unit.
Poor contact of the duplexing repickup-motor connector
Reconnect the connectors of the duplexing repickup motor (J1771), intermediate (J1908, J1939, J1941) and the duplexing driver PCA (J4104).
The duplexing repickup motor is defective
Replace the duplexing feed unit.
Doc jam error usually means a jam in the adf (auto doc feed) when feeding a fax or doc to copy.
The most common reason brother mfc,s of this configuration have doc feed issues is believe it or not the hinge that operates the lid/adf, specifically the left side one (looking from the front). Inside the hinge there are two springs exerting tremendous force on the hinge (that enables the lid to stay up by itself) however this force eventually slowly breaks the fulcrum point of the hinge which leads to the lid not closing properly which means a sensor under the lid does not activate properly resulting in the adf stopping and resulting in the machine registering a jam. the difference between the sensor activating or not can be as little as a millimeter and is not often disernable. the hinge needs replacing by a techo.
the other reason could be you just have dirty adf feed rollers, clean them with a cotton rag dipped in metho, open the adf lid and give the rollers a scrub. the rollers should have 'tread' on them similar to a tyre, if not they are worn and need replacing.
One other possibility is there may be a paper fragment left over from a jam removal still caught in the paper path and activating a sensor activator that tells the machine paper is coming or going. most commonly in the section where the paper is looping on its return journey back out of the adf, open the adf lid, have a look with a torch and see how you go.
Clean the rollers and clean the clutches mounted in the duplex cover to the rear of the duplexer Also the fuser mite be bad the fuser inter connects with the duplexer
Have you tried calling tech support for tips on how to retrieve your cd. if you check the instruction manuel that came with your xbox there should be a number for tech support. If that doesn't work they might want you to send them your xbox.
This tells me your DUPLEXER is the one causing the jam, Ok like when you open the duplexer do you see the paper in their second does your copier indicae that the duplexer is in stalled ?m print the config page to verify. if it worked ok until this incident then your paper feed tires in your Duplexer is worn and needs to be replaced, do not do this yourself call a Service tech or A dealer to do so, uf your in CT we can help.
