In the sixth stage, the image is then fused onto the paper by the
fuser assembly. The fuser Assembly is comprised of the heating
assembly and pressure roller. The pressure roller presses the page
up into the heating assembly which then melts the toner into the
paper. The heating assembly consists of a flexible sleeve with a
ceramic heating coil inside. This type of fuser affords “instant on”
fusing with little to no wait time, and low power consumption. See
Figure 11
The transfer roller (which is located directly opposite each OPC
drum), then places a positive DC bias charge on the back of the
ETB or transfer belt. Each toner cartridge has a separate transfer
charge roller. At the same time, the paper is moving between the
OPC drum and the ETB. As the ETB passes the transfer charging
roller, the positive charge is picked up, and draws the negatively
charged toner off the drum onto the paper. This process is repeat-
ed for each color cartridge. As the toner piles onto the paper, the
positive charge on the paper weakens as the paper runs through
each cartridge. For this reason, the charge is increased on the
transfer charging roller for each successive color.
The paper separates from
the ETB belt as the belt
reaches the top of its path
and turns back down to start
the process again. The static
charge on the back of the
paper is decreased with stat-
ic charge eliminator. This
helps stabilize the paper
feed, and also prevents toner
flares (spots) under low tem-
perature and low humidity
conditions. See Figure 10
Figure 10
OPC DRUM/ETB CLEANING
The drum and ETB are both cleaned after the image is transferred
to the paper. A DC negative bias voltage applied to the drum and
both a negative and a positive voltage applied to each of the four
color transfer rollers. This brings a potential difference between
the drum and ETB so that both the positive and negatively charged
residual toner is repelled from the ETB and returned to the OPC
drum. The developer roller is disengaged from the OPC drum dur-
ing cleaning to prevent contamination. The drum is then cleaned
off by the wiper blade. This part is fairly standard; the wiper blade
scrapes the toner off the drum, and the recovery blade guides it
into the waste chamber. See Figures 12 & 13

8. Remove the drive gear and metal bearing from the drum axle. Pull the drum axle out from the cartridge. Be careful of the drum as it
will come loose
9. Remove the drum.
10. On the PCR, note the coating of conductive grease on both
sides of the roller. Normally this is only on one side. For these
cartridges it needs to be on both.
