How to reset fuser counter on CP3525 - HP CP3525DN Color LaserJet Printer

https://fixyourownprinter.com/posts/73873

Remove the back panel and you will see the fuser unit.

Video instructions we made for you to reset fuser unit on MFC or DCP laser printers, including your model:

Did you replace the fuser with a new Lexmark fuser or a refurbished unit? The original Lexmark units have a chip in them that resets the counter when installed. However this only works the first time the fuser is installed. If you install a used fuser in a different printer it will not reset the counter.

You don't. You can't.

When you install a replacement Transfer belt (it has it's own counter chip) that resets the transfer belt pagecount, and as a result clears any transfer belt life related warnings/errors.

When you install a REPLACEMENT Fuser (that has it's own counter chip) that resets the fuser pagecount, and as a result clears any fuser life related warnings/errors.

PLEASE NOTE - The fuser supplied with the DELL 3130 when new DOES NOPT have a counter chip - the fuser life warnigs are triggered by the printer pagecount. Installing a fuser from another printer (even if it has a ZERO pagecount WILL NOT reset the fuser pagecount (because the 'ship with' fuser has no counter chip.

Purpose
When a fuser unit related error (error code C41, C43, C44 or C45) occurs, the set value of the fuser status
counter varies, depending on type of error.
Displaying and checking the set value of the fuser status counter can analyze a cause for the error. If
any of "2 to 9" is set at the fuser status counter, the fuser unit will not be operated for safety reasons.
After the fuser unit related error is resolved, if "0" is set, the fuser unit will be operated as usual. If any of
"10 to 19" is set at the fuser status counter, the fuser unit will be operated as usual, even if "0" is not set
after the fuser unit related error is resolved.
C41: Thermistor or heater abnormality at power-ON
C43: Thermistor abnormality after abnormality judgment

allot of the newer HP printers can not be reset they have a fuse in the new fuser when it is installed it blows the fuse in the new fuser & resets the count.

Do it in Tech mode
Menu # 1 9 3 4 Menu
Navigate through the menus to find the Counters menu, fuser is in there from memory (I reset imaging unit only recently on CLX3185FN but saw fuser in the menu as another option)
Or you can wipe EVERYTHING with "clear all mem" option
Password 1934 worked fine for me

Hit in sequence Menu,*,2,8,6,4
This will put it in maint. mode.
Press 88
That is parts counter reset, scroll down and hit ok on the part you want to reset the counter. :)
