6. Detailed Function Descriptions
Initialization Process and SC Codes
When a drum gear position sensor has found an error, SC code 396 or 397 is shown. The table shows
the steps of the initialization procedure, possible errors, and corresponding SC codes.
The four drums turn at the same time for
seven seconds. The two drum position
Step 1
sensors detect the two drum gear
interrupters several times.
The time lags between detection of the
black drum gear interrupter and
Step 2 detection of the color drum gear
interrupter are checked. The average
6
time lag is calculated.
The black drum turns. The position of the
Step 3 gear is adjusted for the average time
difference.
• If the connector of the black drum position sensor is connected to the yellow drum position sensor
(and the connector of the yellow drum position sensor is connected to the black drum position sensor),
no error occurs in step 1 and step 2.
