Detected a lock signal which indicates overcurrent in the toner supply bottle motor.
Details:
When a toner supply bottle motor is on, it is checked every 100 milliseconds for
lock signals (motor overcurrent 670mA). The following steps are executed every
second.
If the lock signal was detected 9 times in 10 samplings, the lock counter
increases by one. When the lock counter value is 25 or larger, the SC is
issued.
If the lock signal was detected 8 times or less in 10 samplings, the lock
counter is cleared.
Note:
If the samplings end before reaching the tenth time (due to bottle replacement
etc.), the lock counter value is kept as is. Sampling starts again the next time
the motor runs.
The lock counter is cleared when the machine is turned off (also when the
machine enters sleep mode, in which the plotter is turned off) or when an SC
is issued.
Toner is not filled in all colors after determining the SC with any color until the
machine stops.
The foregoing detection is not performed if all revisions of the board (6 bit) are
0.
Toner bottle not set correctly, toner bottle broken, or large torque: After the
machine stops, ask the user to remove the toner bottle, shake it and set it
again. Then cycle the machine off/on to return from SC status.
Toner bottle broken or defective: Ask the user to remove the toner bottle and
set a normal bottle. Then cycle the machine off/on to return from SC status.
Motor defective: Turn off the machine and replace the motor. Then cycle the
