Just reset the pc life and run F8, code 2557 will reset. You will reset the pc life while the right door is open or else anoying buzzer will come everytime you turn ON the sw. I hope you know the right procedures on resetting pc counters. Then add little toner on developer and run F8. Some tricks you have to do in here.... Little dark copies are expected but after a week or two the copies will surely great!

Id say the easiest thing to do would be to replace your fuser.

replace the drum and developer

bonjour j,ai un probleme avec mon imprimante develop ineo+253 m'affiche trouble code c-3821 et cela n,imprime plus s,il vous plait aidez moi.merci

It's toner density sensor problem but first of all check if there is sufficient amount of developer and toner. Low quantity of developer/toner in developing unit also cause this problem.
Reference

My sincere advise is replace the imaging unit, spacer set and developer of your photocopier machine.
