What is the fuser and where in the printer do I find it.

Hello,
50.9 Fuser error message HP LaserJet P4014 P4015 P4515 If you are seeing the message 50.9 Fuser Error on your HP LaserJet P4014, P4015, P4015 series printer, you have either a failing fuser or the wrong model fuser installed in your printer. (The fuser is the consumable part in your printer which heats up and bonds toner to the paper. Usually the fuser gets replaced several times over the life of these printers.)
HP makes 2 different model fusers that look very similar -- the P4014/P4015/P4515 series fuser, and the M600 series fuser. Because of the similarities in appearance, sometimes the wrong fuser gets installed in the wrong model printer and triggers a 50.9 error.
The easiest way to check which model fuser you have installed is to pull the fuser out of the printer and look at the fuser's barcode. It is easy to remove the fuser on these models; if you don't know how to remove your fuser see the removal instructions farther down this page.
Once you have the fuser removed from the printer, look at the barcode as shown below to determine which model fuser you have installed. For the P4014, P4015, P4515 series printers the fuser part# should read RM1-4554 as shown in the picture below.
Either way, whether you have a failing fuser or an incorrect fuser on your LaserJet P4014, P4015, or P4515, you can purchase a quality replacement fuser in the maintenance kit for the P4014, P4015, P4515 series.

Removal instructions: How to remove the fuser from the printer
Turn the printer off and unplug the power cord. The fuser might be hot if you have been using the printer. As a safety precaution wait 30 minutes for the fuser to cool before proceeding.
If a duplexer is installed, remove it from the back of the printer.
Next fold down the rear door.
Flex the plastic arm-hinge (circled in red below) on the left bottom of the door . This will release the tab which holds the plastic arm in place, and will free the door.
While grasping onto both sides of the fuser, push the blue levers upward and pull the fuser straight out.
After you order a replacement fuser and it arrives, you can install the fuser by inserting the fuser and aligning the left side first. Push the fuser firmly on the left side, then the right--listen for the sound of both blue levers clicking into place. If the fuser does not click into place you run the risk of wearing out both the fuser and the gears that drive the fuser prematurely. Re-install the plastic rear output bin and you are ready to print.

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.

Hi hope this helps

the error looks to be low temperature on the fuser

as a repairer of machine I would normally recommend a new fuser unit if you use the machine a lot don't go for a refurbished unit as they just dint last as long but they cost more

hope this helps Ian

50.X FUSER ERROR

alternates with

For help press

A fuser error has occurred.

X Description

1 - low fuser temperature

2 - fuser warmup service

3 - high fuser temperature

4 - faulty fuser

8 - low fuser temperature

(subthermistor

9 - high fuser temperature

(subthermistor)

WARNING: The fuser is HOT. Turn the

printer off and allow it to cool for

approximately 10 minutes before removing

the fuser.

50.1 error - Fuser failure (Abnormally Low

Temperature Main Thermistor), perform the

following steps:

1. The connector between the fuser and the

printer is not connected properly. Reseat

the fuser. Check the connector J5013

between the fuser and the printer. Replace

it if damaged.

2. Break in the main thermistor. Turn the

printer off and remove the fuser. Measure

the resistance between the fuser

connectors J5013LA-2 (MAINTH) and

J5013LA-1 (GND). If it is not within the rage

of 330k ohms to 50k ohms (at ambient

temperature), replace the fuser.

3. Faulty DC controller PCB. Replace the

DC controller PCB.

50.2 error - Fuser Failure (Abnormal Warmup).

Perform the following steps:

1. The connector between the fuser and the

printer is not connected properly. Reseat

the fuser. Check the connector J5013

between the fuser and the printer. Replace

it if damaged.

2. Break in the main thermistor. Turn the

printer off and remove the fuser. Measure

the resistance between the fuser

connectors J5013LA-2 (MAINTH) and

J5013LA-1 (GND). If it is not within the rage

temperature), replace the fuser.

3. Break in the fuser heater. Measure the

resistance between the fuser connectors

J5013L-2 (FSRH) and J5013L-1 (FSRN)

with the fuser removed. If it is not within the

rage of 12 ohms to 52 ohms (at ambient

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.

X FUSER ERROR A fuser error has occurred. 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.

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.

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.

Hi ellenf971:
Here is your problem.
50.X FUSER ERROR
50.2 error - Fuser Failure (Abnormal Warmup).
Perform the following steps:

it if damaged.
2. Break in the main thermistor. Turn the
printer off and remove the fuser. Measure
the resistance between the fuser
connectors J5013LA-2 (MAINTH) and
J5013LA-1 (GND). If it is not within the rage
of 330k ohms to 50k ohms (at ambient
temperature), replace the fuser.
3. Break in the fuser heater. Measure the
resistance between the fuser connectors
J5013L-2 (FSRH) and J5013L-1 (FSRN)
with the fuser removed. If it is not within the
rage of 12 ohms to 52 ohms (at ambient
temperature), replace the fuser film unit.
4. Faulty DC controller. PCB Replace the
DC controller PCB
you will have to get an HP certified technician to replace the fuser assembly.

Hope this helps
