Causes: When turning the power on or when recovering from energy saving mode, the machine performs a BICU self-diagnostic test. If it detects an error, it reports an IPU (LSUNC) error. • Defective IPU or BICU (or bad connection between the ASIC and the LEO, LSYNC Abnormal, etc) • Faulty cable connection between the SBU and IPU (or BICU).
Remedy: • Check the connection between SBU and IPU (BICU) • Replace the IPU (BICU)
Code: SC161-02
Description: IPU error (RI response error)
Causes: Detecting an error on access to the RI. Defective IPU (BICU, ICTL) or RI abnormal performance, etc
Remedy: Replace the IPU (BICU)
Code: SC165
Description: Unauthorized copy protection failed
Causes: • The machine detects that the optional ICIB is not installed or is faulty even if "Unauthorized Copy Protection" in User Tools is enabled. • When the machine is switched on or recovers from the evergy saver mode, it detects that the installed optional ICIB is faulty. • ICIB nlot attached correctly • Defective ICIB
Remedy: • Connect the ICIB correctly • Replace the ICIB
Code: SC195
Description: Machine serial number error
Causes: Comparison of the product identification code in the machine serial number (11 digits). The product identification code in the machine serial number (11 digits) does not match.
Remedy: Re-enter the machine serial number.
Code: SC230-00
Description: FGATE*1 : Does not turn ON. (*1)FGATE: Signals used between the controller and the engine in order to send the information about the sub scan length of the page to be printed.
Causes: GPIO*2 has not been asserted, although the specified time (200 ms) elapsed after setting JOB to be started and reaching the FGAT assert time. Control Board (*2)GPIO: A type of input/output terminal
Remedy: Turn the main power OFF and then ON.
Code: SC231-00
Description: FGATE*1: Does not turn OFF. (*1)FGATE: Signals used between the controller and the engine in order to send the information about the sub scan length of the page to be printed.
Causes: GPIO*2 has not been negated, although the specified time (200 ms) elapsed after detecting GPIO*assert and then reaching the expected FGATE negate time. * This is an I/O pin. Such I/O pins can be used for a variety of applications, depending on the setting. (*2)GPIO: A type of input/output terminal
