Theory of Operation
LSU
■ The LSU consists of LD (Laser Diode) and polygon motor control. When
the controller generate the printing signal LD will turn on and Polygon
motor starts. If the receiving part in LSU detect the beam and then Hsync
is generated. When the rotation of polygon motor is steady, it is time of
LSU ready status for printing. If either of two condition is not satisfied,
LSU error is expected.
Scanner (ADF)
■ Scanning Method: Color CCD (600 x 1200 dpi)
■ Scan speed: SDMP 28 cpm/MDSP 20 cpm
Trouble Failure Analysis
Polygon Motor Error No steady rotation of Polygon Motor
Hsync Error In spite of steady rotation of Polygon Motor,
No generation of the Hsync signal
