Fuser lubricant and pressure roll wiper
4-3
The orange float that indicates the lubricant level may stick to the
reservoir wall. Be careful not to overfill the reservoir or an
overflow of lubricant may occur.
7. Open a tube of fuser lubricant and cut the pointed spout
diagonally. Carefully squeeze the lubricant into the reservoir
until the orange float reaches the top (C), or until you see the
oil reach the top edge below the fuser cap. The reservoir may
require up to two tubes of lubricant if it was empty.
