Automatic Setting Of The Scanning Compensation Parameters Stored In The Eeprom [Function Code 02 - Brother CB200 Service Manual

4.3.3 Automatic setting of the scanning compensation parameters stored in the EEPROM
[Function code 02]
n n
Function
This function allows you to make automatic setting of the scanning compensation parameters so
that the machine will automatically start home-positioning of the copyboard screen and set the
scanning compensation parameters stored in the EEPROM as described in Section 4.3.1 at the
next powering-on time.
You need to use this function when you replace the main PCB but cannot set the scanning
compensation parameters in the EEPROM since only the printer is received for repair.
When the repaired printer is returned to the user and he/she turns on the power, the machine will
automatically start home-positioning and set the scanning compensation parameters without
bothering him/her.

Operating Procedure
At the service site:
(1) Open the paper compartment cover and hold down the COPY ALL and FEED keys for 15
seconds.
(2) Press the FEED key with the paper compartment cover opened.
The machine writes the automatic scanning parameter setting code into the EEPROM and
returns to the regular operation mode.
At the user site:
(1) Power on the machine.
The machine automatically starts home positioning of the copyboard screen and sets the
scanning compensation parameters in the EEPOM.
Procedure, (2).) After that, the machine will clear the automatic scanning parameter setting
code.
If any error occurs during this procedure, the machine scrolls the copyboard screen again until
it detects another black HP mark and tries to set the scanning compensation parameters
again. If the error still persists, the machine scrolls the copyboard screen again until it detects
another black HP mark, prints an error code, and then returns to the regular operation mode.
The automatic scanning parameter setting code will not be cleared.
