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

Read pdf about fuser, and about drum try to change nvm 954-837(Y), 954-838(M), 954-838(C),954-839(K) threshold for rotation.
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?
what i do here is replace the rfid chip to a new one if the condition of drum still good now can get the chip easily in the markets
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.
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.
GOOD JOB GRAVE ROBBER! YOU have unearthed an 11 year old dead thread... and your machine isn't even the same model.
NOW go start a NEW THREAD detailing all the issues... what has been done/tried.. all life counts on supplies/PM parts .. errors codes
and you have earned a red card!
