Diagnosis
IMPORTANT
• The output lines of R, G and B from the laser control PCB to laser unit are separate.
• Carry out R Laser Output ON, G Laser Output ON and G Laser Output ON of Output Check → Printer → Exposure
Engine Section. If the results are as same as shown below, each laser is normal.

• Laser Synchronous Sensor:Synchronous
• Polygon Mirror Frequency:2043±7
• If all lasers are abnormal, the synchronous sensors (in the laser unit) may be defective.
