shown. The table shows the steps of the initialization procedure, possible errors,
and corresponding SC codes.
Initialization process
The four drums turn at the same time
for seven seconds. The two drum
position sensors detect the two drum
gear interrupters several times.
Step 1
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
time lag is calculated.
The black drum turns. The position of
Step 3 the gear is adjusted for the average
time difference.
NOTE: If the connector of the black drum position sensor is connected to the
magenta drum position sensor (and the connector of the magenta drum
position sensor is connected to the black drum position sensor), no error
occurs in step 1 and step 2.
