Open Heat Error

We changed the fuser unit out on this printer a few weeks ago. Now it has a "OPEN HEAT ERROR" on screen, that changes back and forth to "PC Print Pending" message. I have cycled the power and the error comes up right away. I have not looked at the fuser unit yet. I amgoing to take a look at the lamp and look for any fuses or even a thermal switch. Any other input would be appreciated. Thanks.

My problem was that I forgot to plug the fuser back in - there are 2 connectors - one on the right and one on the left

You need to make sure the voltage of the fuser is compatible with your printer. It can bring up all kinds of errors aswell as a burning smell.

I was gettng dirty copies and a Dell Rep suggested I needed to replace fuser. Ordered a new one, installed it with Dell's help and the "open heat error" started up. We then put the old fuser back in and the same problem continued...."open heat error". I'm wondering if something else may be in play...I've unplugged, replaced and started over but none of it helps. Perhaps there is something that needs to be reset, etc when installing this part. I did not have this error until I installed the new fuser.

This is fuser unit error code, you can try to reset it might work, but if the erorr code came back then you need to change the fuser unit.

In order to reset this code: follow those steps
on the panel press 1087 1087
The screen will change to service mode

now look at the screen and you will see Excute.
Select Excute and press the Start key.
The Machine will rebot or it will asks you to turn it off and on.

Dell 1600n low heat error

Remove the fuser lamp and put it back in place, it is not heating properly.

Have an exellent used HP 8100 printer in home for private and at-home work use. Replaced paper pickup-up assy less than 1000 pages ago, fuser six months ago. No other obvious problems. Just a couple weeks...

hi warren,

If you can open the printer and detach paper assembly a while then put it back firmly,then also the fuser assembly..see to it that no other particles or foreign materials inside the printer and all were aligned.

Hope it can give you idea.


I have Xerox Phaser 7400 with an error 928 we changed the fuser 2 weeks ago now the error has come back

Error 928 refers to the fuser motor failing. Problem could be with fuser motor, motor drive board or engine board.
One other possible cause would be if you are sending too thick a card stock through the machine, this can cause drag on the fuser which the machine interprets as a motor failure.
Hope this helps.

Dell 1600N Multifunction printer problem.

Fuser issues - if problem is reoccuring then you are looking at more expense, are all vents free of obstructions (folders leaning on machine sides/rear) is machine being flogged, is power supply consistent, maybe even fuser bought was faulty, many options, try doing a warranty claim on fuser or replace again, even better get another printer, welcome to our throw away world!
