Items on the Log Sheet
[A]: Serial Number and Model Name (Printer ID)
The serial number and model name are stored in the NVRAM on the printer control
board. The Printer ID consists of the serial number and the model name together.
- Serial Number -
The 8-digit serial number is stored in the factory. Each printer control board has a
serial number and it is printed on the PCB.
Normally, when the printer control board is changed, the NVRAM on the board is
removed and then installed on the new board. In this case, do not change the
serial number (the machine's Printer ID must never be changed, regardless of the
printer control board serial number). After clearing the NVRAM or replacing the
NVRAM, the original number must be stored again, using 'Serial Number' in
service program mode.
See the "Printer ID" section for the purpose of the printer ID and how to store it.
- Model Name -
The model name is the same as the product name input with service program
mode. The model name is stored in the factory and is used for the "plug and play"
name. Normally, the product name does not have to be changed in the field. After
clearing the NVRAM or replacing the NVRAM, restore the model name using
'Product Name' in service program mode.
NOTE: When the model name is restored by service program mode in the field,
the NVRAM will be partially cleared (user settings such as print quality
settings and system settings on the configuration sheet are reset).
If the NVRAM was cleared and the product name was lost, when the log sheet is
printed, "?????" is marked on the log print.
Refer to the "IC Card Boot Service Menu" section for how to reset the NVRAM.
[B]: Engine ROM version
The engine control board firmware version. This firmware can only be updated by
replacing the EPROM on the engine control board.
