Gp 5.2 Paper Transportation - Xerox DocuPrint N2025 Service Manual

The toner image on the paper transferred from the drum surface is easily disturbed by a
light touch with fingers. The paper with the transferred toner image must be passed
through the Fuser assembly to fix the toner image to the paper. The toner is melted and
bonded to the paper by heat and pressure applied by the Heat Roll and Pressure Roll of
the Fuser assembly.
7. Cleaning
This step removes the remaining toner from the drum surface to prepare the drum surface
for the next cycle.
The toner is scraped off the drum surface with the cleaning blade. Figure 9
Figure 9 Cleaning
NOTE: The toner scraped off by the Cleaning step is collected in the used toner compart-
ment separate from the fresh toner compartment. The transfer rate is greater than 90%,
but varies according to the image coverage and the environmental conditions such as
temperature and humidity. Used toner cannot be used again.
At the beginning of each printing operation, the whole drum surface is scanned with the
laser light to completely remove any charge on the drum surface remaining from the previ-
ous printing operation.
At the beginning and end of each consecutive printing operation, a high negative voltage
is applied to the BTR to clean the BTR surface by transferring any toner which has stuck
to the BTR during the previous printing operation to the drum surface.
