Brother MFC5100C Service Manual page 18

In the Head Info. box, type upper 12 digits (e.g., 66667F657031) out of the 13-digit property
code (enclosed with asterisks, e.g., *66667F657031H*) which is printed on the bar code label
attached to the print head unit. Then press the Enter key.
The setup utility will transmit the entered data from your PC to the facsimile machine and
then it will terminate.
The facsimile machine will automatically return to the standby mode.
(3) To check whether the entered head property is correct, make the machine enter the
maintenance mode (refer to CHAPTER 5, Section 5.1) and then press the 7 key twice.
The facsimile machine will print out the Equipment's Log. On the line about 1/3 of full length
of the log sheet below from the top, the 12-digit code will be printed.
(4) Check that the character string entered in step (2) is printed in "XXXXXXXXXXXX."
If it is OK, press the 9 key twice to exit from the maintenance mode.
If something other than that is printed in XXXXXXXXXXXX, check the connection between
the PC and facsimile machine and go back to step (1).
