2.1 WHAT ARE SC CODES?

If an error occurs during operation, the machine displays an SC code ("SCnnn" ,
where "nnn" is a three-digit number). The machine stops and cannot be used when
an SC code is displayed.
If an SC code appears:
1. Write down the SC number.
2. Turn off the main power switch.
NOTE: The main power switch is the switch on the lower left side of the
machine under the hinged plastic cover.
3. Wait a few moments, then turn the machine on again.
In most cases, cycling the machine off and on will restore it to full operation.
4. If the SC code reappears, check it against the table (see, 2.2 SC CODE LIST).
