FAX-L260i Chapter 2: Technical Reference
4.1 LASER/Scanner Section
→
See Page 2-14
This section comprises a LASER unit, cylindrical lens, 4-faced polygon mirror, scanner motor, imaging
lens, reflection mirror and BD unit. The LASER is driven in accordance with the LASER drive signals that
are sent from the PCNT board. This LASER light passes through the cylindrical lens to fall on the 4-faced
polygon mirror that is rotating at a fixed speed. The LASER light is reflected from the 4-faced polygon
mirror and passes through the imaging lens, and reflects from the reflection mirror to scan the photosensi-
tive drum in the toner cartridge.
4.2 Toner Cartridge
→
See Page 2-14
This cartridge comprises the primary charging roller, developing cylinder, photosensitive drum, cleaner
blade, and toner.
The LASER beam from the LASER/scanner section forms a latent static image on the photosensitive drum
that is charged by the primary charging roller. The photosensitive drum rotates inside the toner cartridge,
and rotation of the developing cylinder causes toner to adhere to the photosensitive drum to form a visible
image which is then transferred to the recording paper at the toner transfer section. Residual toner is then
removed from the surface of the photosensitive drum by the cleaning blade.
4.3 Toner Transfer Section
This section comprises the transfer charging roller and the static eliminator. The recording paper passes
between the photosensitive drum and the transfer charging roller, and the transfer charging roller is charged
with a charge opposite to that of the toner to transfer the toner on the photosensitive drum to the recording
paper. The charge on the rear side of the recording paper is then removed by the static eliminator.
4.4 Fixing Section
→
See Page 2-15
This section comprises the fixing ass’y and pressure roller. The fixing section on this machine is an on-
demand system that uses fixing film with low thermal capacity.
The toner that was transferred to the recording paper at the toner transfer section is fused to the paper and
fixed as a permanent image.
The fixing ass’y has a built-in fixing heater and thermistor. The fixing temperature is controlled by the
printer controller on the PCNT board.
