How to Install a Fuser Maintenance Kit in the HP Color LaserJet CP4005dn Laser Printer
In the first step of the replacement procedure, you must turn the laser printer off, and then wait at least 10 minutes to allow the installed fuser to cool. Next, you must open the top cover, and then remove the exhausted fuser assembly unit by pulling its purple handles upwards. After that, you must unpack the new fuser assembly unit, and then insert it firmly into the HP Color LaserJet CP4005dn Laser Printer. Finally, you must close the top cover of the laser printer. Please note that the new fuser assembly unit contains a fuseable link that is opened during the initial installation, which resets the fuser counter.
