5.1.4.2

Creating of Head Calibration Data and Writing it into Flash ROM

(Function code 02)

Function

This procedure scans the "Print pattern for creating head calibration data" sheet (see

page 5-8

)

placed on the scanner glass of the document cover, creates the head calibration data using the
scanning result, and writes it into the flash ROM on the main PCB.

Operating Procedure

Notes

•

Before proceeding to the procedure given below, use Function code 55 (described in

Section 5.1.4.15 "Acquisition of White Level Data and CIS Scanner Area Setting
(Function code 55)"

). If not, this function may fail to create head calibration data

correctly.

•

Make sure that all of the scanner cover (scanner unit), document cover and ADF cover
are closed.

•

For higher precision of uneven printing correction, use the recording paper specified
below to print the "pattern for creating head calibration data."

(1) Drag and drop the "head_calib.prn" onto the Brother Maintenance USB Printer driver icon

in the Filedrgs window.

The machine displays the "RECEIVING DATA" on the LCD and prints out "Print pattern
for creating head calibration data" (see

page 5-8

for a sample printout).

Tip:

Using Function code 61 (

Section 5.1.4.18 "Printout of PRN/JPEG Files in Memory

Card (Function code 61)"

) also prints out the print pattern. After printing with a memory

card, be sure to remove the card and then proceed to the steps below.

Note:

Make sure that the USB cable is disconnected.

(2) Set the print pattern on the scanner glass of the document cover.

Note:

If the print pattern has been printed on A4-size paper, set the paper approximately 3

mm to the front from the document guidelines. Improper setting results in an error (Error
code 01).

(3) Press the

and

keys in this order in the initial stage of the maintenance mode.

The "MAINTENANCE 02" and "Set Sheet on FB?" appear on the LCD in this order.

Note:

Pressing the

Stop/Exit

key immediately returns the machine to the initial stage of the

maintenance mode without creating head calibration data.

(4) Press the

Black Start

(

Mono Start

) key.

The machine displays the "Scanning" on the LCD and starts scanning the "Print pattern for
creating head calibration data" placed on the scanner glass.

Upon completion of scanning, the machine displays the "Write Head Calib" on the LCD,
creates the head calibration data, and writes it into the flash ROM on the main PCB.

Upon completion of writing, the "Complete" appears. Press the

Stop/Exit

key to return to

the initial stage of the maintenance mode.

Note:

If an error occurs, the machine beeps and displays "Error No **" on the LCD. Press

the

Stop/Exit

key to return to the initial stage of the maintenance mode and then recover

the machine from the error state, following the table given on the next page. Then go back
to step (2).
