SOURCE: Fuser Error 50.1 Fuser is hot. What is a fuser?

50.1

A low fuser temperature error has occurred, possibly due to an inadequate external or internal power supply.



this basicaly means that either the dc controller board is on its way out (expensive) or that there is a drain on the power line.
if you have it plugged into an extension lead try plugging it directly into the wall socket. if this fails also try using a different power lead (very easy to get hold of and are normaly called kettle leads)

Hope this helps

Replace the Printer Engine Controller PWB
8 Measure the voltage between P401-1 and P 401-4 when the Fuser Fan cycles up and down. There is 24VDC between P401-1 and P401-4 when the fan is rotating and 0VDC when the fan is off.?

Develop ineo 501, machine stopped, showing " have the fusing unit replaced soon, contact the service representative" -no error code. There is also "license management error occurs" but this promt was way...


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.

Hp lj 4100 50.2 error


is this error on a lj4100 or on a cm1017?
if on a 4100- then the complaint is that the fuser has not reached the required temperature in the allocated time- replace fuser kit with CORRECT fuser ( lm4100MKIT) and not a 4000 fuser which is not the same even though they look like each other.
if its a cm1017 then the error is poor communication with the thermal resistor measuring the fuser temp. again replace fuser kit to resolve

Xerox 6280 gets error message replace fuser kit, it was replaced and still has the same message


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.

Printer keep says replace fuser kit


These is a part on the fuser called a fusable link that blows the first power up cycle and resets the replace fuser message. It sounds like the fuser you installed is a remanufactured unit that was not professionally rebuilt. Contact the place of purchase and get a replacement. The message can only be reset with the fusable link on the fuser.

When I turn the Printer on, it will initialize and then display an error message "50.7 fuser error" and will not get to 'ready mode' for printing


1. Turn the printer off, wait 10 minutes, and then turn the printer on. 2. If the message persists, reseat the fuser. If that does not work, replace the fuser. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace the engine controller board. http://printertechs.com/tech/error-codes/error-codes-50-59.php

I have a Lexmark c540n printer that has the fuser error of 122.03 service fuser error how do i clear it on my machine I don't have tick btn any help would be great


you can reseat the fuser, and see if the message goes away. Or you will need to replace the actual fuser assembly. unfortunately you can't just remove/clear the error. see picture attached as this is what the fuser looks like

after you replace it let me know if you still receive the error.

925 service fuser error


A 925 Fuser Error indicates that the wrong fuser lamp or the incorrect fuser assembly is installed.
  1. If this error appears shortly after the fuser unit in the printer is replaced, put the old fuser unit back in.
    If the error message goes away with the old fuser unit, please check that the new fuser unit is the correct one for this printer model.
  2. If the printer has not recently had its fuser replaced, plug the printer directly into a wall outlet. Surge protectors and power strips can sometimes regulate the voltage to a fault for the printer. If the printer is already on a wall outlet, plugging the printer into a different outlet may solve the problem. Keep in mind that there is no need to have the printer connected to a computer during testing for a fuser error as any pages to test the functionality of the printer can be processed internally.
  3. If you have tried the printer on other wall outlets and the 925 Fuser Error still appears, the printer will require service to clear the message.

RESEAT FUSER


Hi G,

99% of the time the error is the fuser. Either it is damaged, or just not locked in place, and with power off, reseating it will fix the error. Since you just replaced the fuser, I guess the question is did you do it because it was also giving this error, or because it reached EOL ( end of life ).

If it was for EOL message, I would try reinstalling it. If the "reseat fuser" error goes away, but comes back with the new fuser again, then the new fuser you purchased is defective and should be returned or exchanged.

See the information below to correctly troubleshoot your issue.

The following steps are the troubleshooting steps that should be followed for error code 010 397.
First, the definition of the failure is <IOT Fuser Failure>, and means a Fuser Error is detected.

1) With power off, reseat the fuser by physically removing it from the printer, then reinstalling it and locking it in place. Turn the power back on. ( if the error is still present, proceed to step 2 ).

2) If reseating the fuser did not resolve the problem, Replace the fuser with a known good fuser.
( if problem is not resolved, proceed to step 3)

3) Replace the LVPS ( low voltage power supply ). ( if problem not resolved, proceed to step 4 ).

4) Replace the PWBA MCU ( printed wiring board assembly - machine control unit ).

END of troubleshooting.........

In most cases, the fuser itself is the problem. If you tried to reseat or replace the fuser while power was still on, the LVPS could have been damaged just as if there were an electrical storm.

Hopefully this helped.
