If not, attach the ferrite core to the harness. 5 Check that CN29 harness on PRCB has a ferrite core. 3 Check the harness for proper connection and correct as necessary. 5 Change PRCB.ġ Clean the connection between the toner cartridge and the machine if dirty. The error was found when reading out the counter value.ġ Clean the connection between the imaging unit and the machine if dirty.An error was found when reading or writing data.4 If the above actions do not solve the problem, contact KMBT. During the period, the control panel backlight stays off.) Make sure that malfunction codes other than C2650 or improper IU/TC placement is not detected. (One minute is spent to prepare the new SV ERB for use. Turn ON the main power switch and check to see that warm-up is started. Replace the current SV ERB with a new one. When taking the above steps, check whether PRCB is defective or not without replacing the SV ERB.When the trouble cannot be solved, reinstall the removed PRCB to the original board. Make sure that malfunction codes other than C2650 or improper IU/TC placement is not detected. After completing the firmware update, turn OFF and ON the main power switch and check to see that warm-up is started. (When using a PRCB of another machine in service, be sure to use a PRCB installed in the same model.) 2.2. Turn OFF the main power switch and replace the current PRCB with a new one. The machine detects that the service EEPROM board is not loaded in position.ġ Check the connector (CN23PRCB) on PRCB, the connector (CN1SV ERB) on SV ERB, and the harness between the boards for proper connection and correct as necessary.The error was found when reading out the counter value.
The re-written data, which has been read out, checked and founded as error, is read out again and found as error.
