"Understanding explains better..."

Service Fuser Error appears when the fuser does not warm to the required temperature. For this error on this Lexmark model T640, the manual states you should power off the printer and power it back on, and if it is not plugged into a wall power point, change it to a power point mounted directly on the wall. Personally, I never got a Lexmark printer to work doing this, but this is in the manual. If this won't help, and the printer is under warranty, you should log it in with the servicing company.

If the printer is out of warranty, your next option is to change the fuser which costs around $350, so I think you would be better off getting a new printer unless you find a second hand one on Ebay.

This jam is refering to back door, jam in fuser (hot bit) Double check no paper is wraped around fuser rollers.

These machines have a fuser at rear if you look at he fuser from the back, on it you will see, two thick fuser rollers (ones rubber), paper runs threw these then it hits a little black switch (your machine thinks this switch is activated) and then a series(3,4) of small rubber exit rollers, this switch (between middle and left) can get damaged it also likely that a piece of paper is concertinaed in fuser.

That can be caused by several factors(e.g. small paper stuck inside the printer, the roller or the toner cartridge). But here's a link to the Lexmark website to guide you on what to do when having this kind of problem on the Lexmark T640 printer. http://bit.ly/cFLEel. Hope this helps. If all else fails, I suggest you contact Lexmark Technical Support for further assistance.

you need to change the high voltage power supply to fix this error i have found this to be the problem 98% of the time and i do csome 1200+ repairs on these printers a year

Please go www.lexmark.com >>Technical Support.

Place the T640 model number into the first search box. When the T640 block opens up do a search for "ENUS23982."
