SOURCE: FUSER ERROR

I just reviewed both of the above fuser issues (50.2 & 50.3). Both are highly likely (even if recently replaced) fuser damaged. I have included below a link to a free HP service manual for your machines. Start on page 309 using a volt/ohms meter to test the fuser. To address the "Guest" inquiry regarding the HVPS, there is a separate HVPS however please be aware that it is not part of the fusing circuit in this machine. If anything it would be the LVPS (Low Voltage Power Supply) however very remote. Odds are maybe 1 in 200 on your best day. I'd put 10 fusers in the machine before I bought 1 LVPS. This machine is known to eat fusers. The HVPS and LVPS at this time are just about bulletproof. PLEASE TRY TESTING THE FUSER AGAIN USING THE MANUAL PAGE 309 TO 311. If your really want the power supplies though, they are on the part number list at the end of the manual. I just looked it up and we have repaired 74 of machines to date with not one PS ever used. 59 of the 74 have been for fuser issues.

Here's the manual link:

Hope that helps you both. :)

SOURCE: 50.1 fuser error on HP 8150 LaserJet Printer

I have a HP LaserJet 5000 with a Fuser Error code 50.1, meaning low temp. I am not a tech, but I have been repairing my own cars, printing presses, computers, printers and anything else that breaks for over 35 years. The previous fuser on my LaserJet 5000 lasted over 7 years and while I was not getting any error codes, it was not fusing laser plates as well as I liked. Until recently I had two HP 5000 LaserJets and was able to trouble shoot by swapping parts. I replace a bad DC controller board in this particular printer about a year ago. Shortly after that I replaced the fuser with a genuine OEM HP fuser and it fused great for nearly a year. A few weeks ago I had a massive paper jam in the fuser and a day later got a Fuser Error 50.1. After checking the Internet I determined it might have broken the ceramic heating element. I swapped fuser with the one in my other identical working printer and the fuser error went away. I swapped the fusers back again and the error returned, pretty much proving the problem is in the fuser. Since I am not made of money I figured I could rebuild a fuser just as well as anyone else so I went on a search for the parts, but it was like calling Area 51 and asking what they were hiding. The service manual indicated some ohms testing to be done on the problem fuser and all results came back showing all the correct readings. I knew the fuser was the cause of the error, and the parts were not cheap so I carefully disassembled the fuser to see if I could isolate the exact part that was broken. The ceramic heating element and everything else looks fine. One detail I had found odd was that the printer used to take a couple of minutes or more to heat up, but I now got the fuser error 50.1 within 15 or 20 seconds of powering it on. This made me wonder if it would even have enough time to heat up enough to know it had a low temp problem. I thought the problem might be in the part that actually measured the temp. While I had the fuser apart I found one small resistor attached to the frame directly under the main drive gear. I did an ohms test on the resistor and it showed bad. I really hate to tear my good fuser apart to swap the resistors for fear I might burn it up to, so has anyone out there heard of a bad resistor causing a 50.1 error? I found only one reference on one site about a different LaserJet with a 50.1 code because of a bad resistor, and I have no idea where that resistor is on that particular printer. I know I could have just replaced the fuser by now, but I like to learn how things work and solve puzzles like this one. I am hoping some of my info may be of help to someone and if anyone has anyone ideas or thoughts on my comments, I would love to hear them. I will go on a search for a resistor next week and see if that helps. I hope to hear from someone soon. Thanks and God bless. James

You can reseat the fuser or you will have to replace the fuser. Please note the these machines the fuser is located in the middle of the machine. Most likley it's a bad fuser.

Turn power off. Wait at least 30seconds before powering on. Make sure power cord is not plugged into a surge protector.
If error returns contact HP.

SOURCE: 50 fuser error in hp

An error 50 on most HP Laserjet printer indicates the fuser has a problem. Most common problem is the heat lamp burned oou. The lamp is not a replaceable item unless you re a top notch technician. The fusing assembly however is usually a relatively easy replacement requireing only twisting of a couple of latches or removal of a couple of phillips screws.
The part # for the fusing asm for the HP LJ 3030 is RM1-0865-000CN.
These can readily be found online for anywheres from $120 to $250.

What is the solution for fuser error 50.4 in laser jet pro 400


Most likely you will need to replace the fuser. Try plugging the printer in to a different outlet than it is right now. If you get the same error then you can be pretty sure the fuser is bad.

50.0 fuser error


Hi,
SOLUTION: Follow the steps listed below:
  1. Turn the printer off and unplug it for 30 minutes; then turn the power back on.
  2. Try a different power cord. DO NOT use extension cords to plug the printer in.
  3. Remove the surge protector or UPS/CVT device and connect the printer directly to a power source.
  4. Try a different electrical circuit. There could be an issue with the line voltage going into the printer from the power source.
  5. Turn the printer off and unplug it. Let it sit for 30 minutes to let the fuser cool off. Carefully remove the fuser; IT MAY STILL BE HOT USE CAUTION. Examine the fuser, if any damage is apparent the fuser may need to be replaced. If no damage is noted reinstall the fuser, plug the printer back in and power it up.

Hp laserjet 3055 has error message on copying "50 fuser error, turn off then on". Restarting brings on the same message when copying.


The all-in-one has experienced an internal hardware error.

1. Turn off the power by using the power switch, and then wait at least 30 seconds.
2. If a surge protector is being used, remove it. Plug the all-in-one directly into the wall socket.
3. Check the cabling connections to the heating element.
4. Turn on the power and wait for the all-inone to initialize.
5. If, the error persists, replace the fuser.
NOTE The device power mustremain off for at least 20 minutes forthe fuser to cool down and correctly reset.
Turn off the power switch, wait at least 20 minutes, and then use the power switch to turn on the all-in-one and wait for it to initialize.

It says c then 50


A C5 error code means that you have a problem with the fuser unit. The fuser is not warming up correctly. You will mostly have to replace the upper fuser roller or the upper fuser unit. The heating ubit sometimes arch's though the fuser roller. You will need to resolve the problem before the code clears, you may also have to replace the fuse on a small PCB next to the rear of the copier..... Good Luck

010 397 Error Message on Dell 5100cn


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.
