The "SC Table" section shows the SC codes for controller errors and other errors. The latter (not
controller errors) are put into four types. The type is determined by their reset procedures. The table
shows the classification of the SC codes.

switch on (See SC 672). All SCs are logged. The print log data (SP5-990-004) in SP mode can check
the latest 10 SC codes detected and total counters when the SC code is detected.
• If the problem concerns electrical circuit boards, first disconnect then reconnect the connectors
before you replace the PCBs.
