Claim:
An improved fusing system for a printing apparatus, the system comprising: a fuser roll; a take-up roll and a source roll, each one of the take-up roll and the source roll being movable; a strip of flexible material for at least one of cleaning and oiling the fuser roll, the strip of flexible material including a first portion, a second portion and a third portion, each one of the first, second and third portions having a first side and a second side; wherein the first portion is disposed adjacent the take-up roll, the second portion is initially disposed adjacent the source roll, and the third portion, which is disposed intermediate of the first portion and the second portion, is taken up by the take-up roll as both the take-up roll and the source roll are moved, and wherein the first side of the third portion contacts a portion of the fuser roll for achieving the at least one of cleaning and oiling; a first detectable mark positioned on the first side of the second portion; a first sensor positioned adjacent the first side of the strip of flexible material, the first sensor being configured to output a first signal indicating that a substantial amount of the third portion has been taken up by the take-up roll when the first sensor detects the first detectable mark; a second detectable mark in the first side of the second portion; and a second sensor positioned adjacent the first side of said strip of flexible material, the second sensor being configured to output a second signal indicating that substantially all of the third portion has been taken up by the first roll when the second sensor detects the second detectable mark.
