I have a 5200 I'm trying to repair at the moment. It keeps "jamming" as the first page exits the printer. It gets half way out and the whole printer stops. If it's printing one page, removing and replacing the cartridge solves the jam and it pushes the sheet out fine (it's all fused and ready to go). If there is more than one page then I have to remove the sheet of paper under the cartridge before it will continue... only to jam on the next sheet exiting the printer.
I read some where (lost the page now!) of someone having a similar issue and fixing it with a new fuser, thus replacing a paper sensor. I've just installed a new fuser and exactly the same thing is happening, at a bit of a loss really!
I'm going to try and reset the NVRAM if I can get the menu to appear... but any other suggestions would be accepted graciously!
