It all started after moving equipment from one place to another.ġ. – All prints came out with a green / blue tint. If this abnormal print appears, perform AUTO ADJUSTMENT if the laser unit is Type A.Īuto tuning may temporarily reduce the symptom. * In the QSS-31, the exposure speed is 89 mm / s. * Even in QSS-30, since the frequency is different for type B, lines appear at intervals of about 2 mm. Thus, when using the Type A laser unit in the QSS-30, lines appear at 4mm intervals. The exposure speed on the QSS-30 is 50.8 mm / s, noise appears 12.5 times / s. To maintain a constant amount of light, the PD (photodiode) at the head of the B (G) laser monitors the amount of light and feeds it back in at regular intervals to regulate the LD electric current. If the light emitted by the LD is unstable, the light beam strength (amount of light) emitted after the LD (laser-> medium-> SHG-> reference) will also change. Possible Cause: Type A laser unit is defective.ĭue to a malfunction of the laser diode (LD) in the blue laser head, the light emitted by the LD becomes unstable, causing a low-frequency noise (12.5Hz) on the laser head, and the laser beam strength changes. – Lines represent the vertical direction in relation to the direction of paper advance. – Yellow lines appear throughout the print.
