Sir/Mam, Something is preventing one of the fuser (Hot Part) roller from turning had this happen at a school teacher melted a transparency in the fuser by using a ink jet printer type transparency on this model copier cost the school 2000 dollars. Anyway hope you did not melt a transparency any way check the fuser the hot part for paper that may have wrapped it self around the orange rollers in the Fuser (The hot part of the copier if so you need a new fuser or have a tech come out and see if he can remove it. IF you use any type of tool you can damage the roller and your copies and prints will have marks all over them. Trying to reset the code prior to verifying the motor can turn allows the possibility of burning the motor out and taking the control board that controls it now your talking 3 to 4 thousand dollars
This fuser error can lead up to a series of solutions, and I will list them in order of easiest to hardest.
1) Unplug your printer from the wall, wait 5 minutes and plug it directly into the wall, UPS battery backups and Surge Protectors can trigger this type of error.
2) If you have another one of these printers, try swapping the fuser roller with another one while the power is off and see if the error persists upon startup.
3) Last and least desirable, you may have a failed Engine Controller Board, which is responsible for among many things, making sure the fuser is at the proper temperature and has no tears. Be aware that this repair requires a pretty serious disassembly, and can be daunting to a newcomer.
The fuser is actually considered a part replaced with routine maintenance, around every 100,000 to 150,000 pages. It is what is responsible for the carrying the charged toner particles and heating them up to melt them onto the target paper (New HP Laserjets use a wax based toner for better environmental impact) Problems with the fuser generally show themselves as lines or splitting images on printed paper, but if serious enough (as in a tear on the roller) can cause the printer to cease printing to prevent serious damage to the interior of the machine.
A 50.2 error is a fuser error. This is the assembly that heats up and fusees the text to the paper. It is located at the top of the printer. The fuser is not warming up and is throwing this error. The fuser would have to be replaced.
Bad Fuser. Google a business called The Parts Drop to order.
It is not difficult to replace. Remove the back cover, 4 phillips screws pull out slide the new one in.
I would remove the fuser first though. And check the plastic in the ends of the fuser. If they are melted, then the power supply has failed and you will have to replace both the fuser and power supply. If the fuser looks normal no plastic on the end of the rolls melted, then just replace the fuser.
1.try stopping the printer halfway thru a print cycle if you can stop a paper under the print cartridge and before the fuser you can check for print defects on the page before the toner is melted into the paper.
if no defects are found then your fuser may be defective,usually the upper fusers film sleeve tears -testing this way can save you from trying a new cartridge$$$
You can try to lower the temperature of the fuser while printing the sleeves. From the "menu", select "maintenance", then "adjust fuser". The default setting I believe is 0. it can be adjusted from -4 to +2. Lower the setting to -1 and test. If that does not work, try -2, and so on... until the lowest setting at which it does not damage the sleeve. IF you go all the way to -4 and it still warps, then you will not be able to use it for this purpose. Do not forget to set the fuser BACK to the default setting after printing this media.
Failure to warm would suggest the fuser unit is failing and the machine is failing to reach the temperature that toner melts and fuses to the paper. The machine should display error 76 or 77.
Try this ONCE only!! till the after 99 bit. Hit menu, *,2,8,6,4 quickly if all the button flash and maintenance is displayed enter 99. Now if the error reoccurs you need to replace your fuser unit as it failed as opposed to just malfunctioned.
It will melt if there is a problem and you keep repeating this process. So please only once. If it takes you a few goes to get into maintenance modes its ok but the reset of 99 do only once.
Cant picture you fault, if fuser is over 12 months old then change it, it should have smooth orange rubber rollers, not serviceable item normally.
I'm not sure but I think you issue may be you are not setting the paper type correctly to suit media you are printing on ie card. If this is the case fuser runs at wrong temp an fails to apply enough heat to fuse/melt the toner into the paper and fuser rollers gunk up.
