How to get into service mode on Docucolor 250 fault code 042-346

Does anyone here now how to get to the "service program mode" on the Docucolor 250 ?
We've replaced the IBT belt, but still have the fault code 042-346.
The only area I can get to is the "System Administrator menu".
Also I"m in need of service manual for this model, but can't find it anywhere.
Thanks.

 

Press 0 for 5 seconds, then press start
Type in 6789 and confirm
Press the log in/log out button
Go to systems settings -> common settings -> maintenance

 

I am trying to folow the instructions for getting into the Docucolor 250 service mode. Do hold 0 for 5 seconds while turning on the machine, then proceed to Start?

 

Yes that is correct but you need to keep holding the o button while pushing start.

 

Press and hold the 0 key for 5 seconds, then while still holding down the 0 key, press the Start button. But are you sure that the code in not 042-326

 

so If this fault is 042-326 was declared 3 times in succession, the print mode will be disabled. In order to clear this condition, reset NVM location 741-105 to 0 by entering diagnostics.
