Replace Fuser Message Still Appears

that unit is manufactured my konica minolta. it is a Konica Minolta Bizhub 501 and will use the same fuser even though the image units, toners, and transfer belt have to be chipped for the ineo. There is a picofuse in the fusing harness that blows as soon as it is installed and that starts the fuser life counter. the counter is reset when a new fuser (or new fuse, if the fuser is still good) is installed. You will need to replace the fuser for the message to go away.

This is an easy one.


The original fuser supplied with the printer DOES NOT have a counter chip. Instead, the PRINTER assumes that when the number of pages printed reaches the level at which the fuser needs to be replaced, the printer issued the REPLACE FUSER message.


If you replace the fuser with another that has come OUT OF a new printer (i.e. a 'PULL' from a new unused printer), since it has no counter chip of it's own, the printer assumes the fuser pagecount is the same as the printer pagecount (because there is no information to read from a fuser chip), and still wants the fuser to be replaced.


A new REPLACEMENT fuser from XEROX, or a CORRECTLY refurbished fuser WILL have a counter chip, and therefore clear the REPLACE FUSER message.

If you replaced with new fuser even getting same error, then check,
>Check the fuser connector (J5001). If
it is broken or damaged, replace it.
>. Check the connector (J1025) on the
DC controller PCB.
>. Replace the DC controller PCB.

There is a switch that should "close" when the door closes.
But, that switch either is damaged, or it is not sending the "now closed" signal to the printer.

Check that there is no obstruction blocking that switch, nor any dust plugging it up.

Hi Good day!! It may be the fuser problem. u may need to replace the fuser or buy a new unit.

Replacing the fuser
When 80 Fuser life warning appears on the operator panel, replace the fuser soon. Make sure one is on order. See
Ordering a fuser for more information.
When 80 Replace Fuser appears on the operator panel, replace the fuser immediately.

......From the Lexmark users guide.....

transfer belt cleaner error
replace the transfer belt unit

The connecter between Fuser and printer is not connected properly. Reset the fuser.
To remove the fuer fuser and measur resistance between the fuser connectors J50132A-2(mainth)and J50132A-1 (gnd) if it is not within the range of 330k ohms TO 50k ohms at (abient temp) Replace the fuser.

The fuser replacement interval is 60,000 prints . The machine will print indefinately otherwise.The message is just a reminder.

Hello, even i am having the same problem. I was looking online and found this stuff: step 1: Turn off the printer and switch it on after 20 mins. Step2. If the above step doesnt work then remove the fuser and replace it back again. Step3: if the above two stpes doesnt work and you still have that error message, then remove the fuser and check the impedance, if its below the required level(i dont know whats the required impedance is), then you have to change the fuser. I tried both step1 and 2, it still shows the error message, i guess i will have to change the fuser. Let me know if this helps Susheel
