Theory of Operation
Scanner Latch
The Scanner Latch works with the ADF Lever to prevent the simultaneous
opening of both assemblies. When the Scanner is opened, the ADF is locked
closed. Likewise, when the ADF is opened, the Scanner is locked closed.
Pulling the Scanner Latch Lever disengages the Scanner Lock Pawl, allowing
the Scanner to be opened.
If the ADF is open, the ADF Lever locks the Scanner Latch mechanism to
prevent the Scanner from opening.
Laser Assembly
The Laser Assembly in the Phaser 6115MFP printer has two laser diodes.
The laser diode control circuitry adjusts the light intensity for each beam
automatically. Image data is transmitted to the laser diodes in the Laser
Assembly as digital signals. The laser diodes convert the image data from
digital signals to optical signals. The Laser Assembly monitors and adjusts the
intensity of the laser beams to attain a stable electrostatic image. The Laser
Assembly is replaced as a complete assembly. Functional components within
the Laser appear below.
