! Explanation (Laser Self-Diagnostic)
" Although various symptoms appear with the troubles related to the laser, Laser Self-Diagnostic is not effective for all
of those symptoms.
The following are the symptoms for which Laser Self-Diagnostic is and is not effective.
Symptoms for which Laser Self-Diagnostic is effective
• ☞No. 06073: Synchronous Sensor error. occurs.
•
☞No. 06076: Polygon Mirror control error. occurs.
• ☞No. 06106: G Laser light source status error. occurs.
Symptoms for which Laser Self-Diagnostic is ineffective
• If the print color fluctuates (light intensity fluctuation)
• If abnormal prints with noise are made
• For errors at the laser temperature adjustment
IMPORTANT
• The Laser Self-Diagnostic has the function to perform voluntarily the synchronous detection which is same as print
operation.
To use this function, it is necessary to make the laser unit under the same condition as that to print. For this reason, it
is required to finish the temperature adjustment in the laser unit.
If replacing the laser unit and checking it with Laser Self-Diagnostic, a certain waiting time is necessary until the laser
temperature adjustment is finished.

Explanation
Light Source Status (R)
Light Source Status (B)
The R laser light source status and the B laser light source status are checked and the results OK or No Good
(failed) are shown.
• OK: laser is operating normally
• No Good: laser is not operating normally
Graph (R)
Graph (B)
Displays in a graph the measured values of PD voltage and LD current for the R and the B lasers
• For details, see
☞Direct modulation of the R and B lasers 35950.
Synchronization
detection value (power)
Asynchronous point
Synchronous Detection
Setting Value
The Laser Self-Diagnostic program automatically calculates and shows a value for stable detection of laser
lights R, G and B.
When lasers R, G and B are output with the maximum light intensity but the synchronous sensor does not
detect lasers, No Good is shown.
