Instructions for the HP CP4025 and CP4525 Fuser Replacement
CAUTION: The fuser might be hot. Allow enough time after turning off the product power for the fuser to cool.
NOTE: The product detects a new fuser using a fusible link that blows after 100 pages have been printed. If a new fuser is installed for troubleshooting purposes, be sure to remove it before printing 100 pages.
1. Open the right-door assembly.
2. Grasp the handles and squeeze the blue release levers.
Pull the fuser straight out of the product to remove it.
Fuser unit life detection
The product detects the remaining life of a fuser. The DC controller recognizes a new fuser from the NEW FIXING UNIT (/FSRNEW) signal. The DC controller determines a fuser’s end of life and then notifies the formatter when a specified number of pages has been printed after the fuser was replaced.
