What is the complete error message?
EL probably stands for end of life on some component like the drum. The complete service manual for your printer is available online here.
There is a reset menu for parts if you push the go and up buttons at the same time.
Though if the drum or another part needs replaced it is advisable to do so instead of just resetting.
