Maintenance kits, otherwise known as "fuser kits," contain a number of replacement parts that often wear out on laser printers, such as rollers, separation pads, and a fusing assembly. These parts are necessary for using heat and pressure to bond the toner to the paper. The maintenance kit should be purchased and installed when your HP LaserJet 2430DTN printer displays the error message "Perform Printer Maintenance."

Place the left side of the roller in place, making sure the spring part of the white plastic bushing is facing down and the grooves match up with the seating. Push down to lock it into place.

Lift the pickup roller out of the printer and remove the small grey rollers from either end. Place these rollers on the new pickup roller. Place the new roller into the printer left side first, rotating it as you slide it to the right. Make sure the driveshaft rests in the slots. Replace the left lever and rotate both it and the right lever down until they lock into place.
Turn off the printer and let it cool for at least 20 minutes. Open the back door of the printer all the way and use a screwdriver to remove both screws visible on the sides. Close the back door of the printer and lay the printer on its front. Open the paper guard from the back of Tray 2. Use a screwdriver to release the two tabs from inside Tray 2.

Remove the main fuser gear from the left side of the printer by depressing the release tab and sliding it off the metal bar. Replace it with the new gear that came with your maintenance kit. Insert the new fuser and secure the 4 fuser screws in place. Repeat all instructions in reverse until the back cover is once again screwed into place.
Open the toner cartridge door. Spread the black tabs on either side of the Tray 1 pickup roller and rotate to release it. Use a screwdriver to pry the blue separation pad on both sides and in the middle until it snaps loose.
