You can try to go in the service menu.
You can find this in the administration menu, go all the way down and you will see "service".
You need to insert the service code : 11434506
From there you can reset the maintenance count i guess.

You would need to log into the embedded webserver to view the configuration page. From there you could screen capture it as I do not believe that the print config page was added until later models.

Check ADF unit (automatic document feeder) working condition.
For diagnoses : Insert few paper(ex:10papers) in ADF unit & do copying, if UR succeed in copying, ADF is working well.. If not check the fault.
HP M4345 facilitated with digital sending option., for configuring digital sending U need to create shared folder with fully permissions in system. Better visit hp site or google to know about how to create folder.. You can do multiple scanning once configuration completed successfully..for more info visit:

This error can be caused by the following:

1. Fuser that is close to end of life. Maximum print quantity is 225,000 pages.

2. poor quality paper, very thin paper never feeds well and will jam.

3. Printing an image that is almost entirely black can cause the paper to buckle before entering the fuser.

Try different paper to see if that resolves the problem.

49.XXXX is a fatal catch-all error. Could be firmware problem, network, print job. If the error occurs when you try to print, clear the print queue. If the error occurs when the printer is just sitting idle, reseat the formatter. Try powering on without the network cable attached. If it still happens replace the formatter. Could be a corrupt print job being sent to printer. Print something else.
