1) First thing is check power source. If you have the printer plugged into a UPS (uninterruptilbe power source) unplug it and plug it directly into the wall. If it is plugged into the wall you might want to try a different outlet to see if it solves the problem.
2) Remove and reinstall the fuser. It may not have seated properly.
#) Make sure you installed the correct fuser. Should be RM1-1082. There should be a sticker on the fuser with this number. See the following article for more info. http://www.partsnow.com/service_today/0705.asp

If you still have the old fuser check also that it is a RM1-1082. If not you may have a euro version machine which would require a different fuser.

If the fusers match up you should check the voltage coming to the fuser if possible. If there is 100- 127 volts where the fuser plugs in you probably got a bad fuser or it was damaged in transit. If there is low voltage or no voltage you may have a board problem. Probably DC controller or Power Supply.

Hello,

Vertical streaks are usually caused by a bad fuser. The fuser roller has a teflon caoting and when this coating gets scratched or worn it causes image defect to appear on the paper. The fuser for the 4250 is part number RM1-1082 and you can get them from Amazon.com or other online sites. Here is a link to an article that shows how the fusers can cause the vertical image defects like you have.

That's a main motor error, something could be jammed in transport, or a generic toner cart. that is too hard to turn, try powering on with toner removed...

Problem is a beam-detect error. There is a problem with the laser/scanner assembly or possibly the DC Controller.
I'd suggest that a qualified printer tech check it out.

Hi,
Depending on exactly where the paper jam is at, you can try removing the front cover to get the paper. There's only a few screw you have to take off.
you can check out this site. PDF document on how to take the printer apart.

Remove the fuser unit and check if there is a residue on the side of the gears. If so, you 'll have to replace the swing gear assy. Partnumber 5851-2766. It is not an easy job!!!
