    Post Xerox 242 (7655) Drum/Fuser reset

    Just had a 242 (7655) delivered and the drum and fuser life is showing low.

    The copy quality is great and I was wondering if they could be reset in any way?

    Does anyone know the NVM codes or is there another way.

    Thanks

    thanks

    Thanks.

    I have changed the 744-354/355 settings to the ones specified but cannot seem to get to the dC135 HFSI to change the threshold.

    I have found dC135 CRU/HFSI but it wont let me change details.

    I dont seem to have adjustments/others in maintainance/diagnostic.

    Just out of interest, what does changing the 744-354/355 settings actually do?

    nvm 744-354/355 extends the fuser life to a specified value (default is 200/210) and we recommend 490/500.

    HFSI 954-842 resets the value of the fuser life

    Also, you need to change Nvm 751-448 to 1 (warns and continues) if you want to use your drum continuously even if it says 'replace drum NOW'

    I would guess dC135 CRU/HFSI is probably reading the useage chip ("RFID chip") rather than the NVM, that is why you can't change it. If you put in a new chip or reset the chip then it should show a new value.

    Incidentally, I don't know why people call it an RFID chip, which usually means an encapsulated proximity device that communicates using radio frequency. Usually it is just a unique ID number, hence the anacronym RFID. But maybe there is another anacronym with the same letters? Or maybe some of the latest machines really do use RFID? Unlikely, I would have thought. The ones I know are simple I2C bus EEPROMs.

    Smile Maybe is because of the paper

    Hello, I have a 242 also, and the fuser life is short because we are using a lot of heavy paper.
    Good luck with your printer.

    Hi Phil B.

    Sorry for my post. I did not take a look when this was posted, and I think you know how it is when machine is not works and customers are waiting for prints...

    Sorry once again. Will open new thread.

    Have a great day.

    Best regards,
    David
