Lexmark T522, T520 Fuser Replacement Procedure

 

 Instructions for the  Lexmark T522, T520 Fuser Replacement Procedure

These machines have a 250,000 PM cycle which is the rating for the fusing assembly. Most your OEM fusers will last the whole life. Rebuilt fusers cost have as much and I’d say they have about half the life cycle of the OEM fusers. With that being said I do, on occasion, run into one that will surprise me and make it the whole life cycle. Most these machine don’t get the heaviest of usage so if they make it to 125 to 175 thousand and the fuser last 3 to 5 years then your in good shape. Below you will find the  Lexmark T522, T520 Fuser Replacement Procedure along with links to purchase a replacement fuser if it is still needed.
