What you are looking for is the Ring Count Delay.

Unfortunately it looks as though this is not an option for this unit.
Here is the manual for the MP C4501.

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.

Laser malfunction; try to reset the equipment as follow:
Shut down from the main power switch wait for a few seconds and then start it up while keeping the 'Utility/Counter' button pressed; keep it pressed until the reset button appears on the touch screen, release the 'Utility/Counter' button, touch the reset button and an OK message should appear below. Restart it normally and it should work.

Purpose
When a fuser unit related error (error code C41, C43, C44 or C45) occurs, the set value of the fuser status

After the fuser unit related error is resolved, if "0" is set, the fuser unit will be operated as usual. If any of

after the fuser unit related error is resolved.

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.

Replace the parts! If it is used you have no idea of how old the parts in it are even if they look good. The counters that turn these messages count sheets of paper not time and the parts may have moisture damage from sitting up.
