<Function>
This procedure adjusts the top, left, right and bottom margins for borderless printing.
Print out a margin check pattern, measure each margin, and enter the measured margin values.
<Operating Procedure>
Before starting the procedure below, be sure to set letter or A4 size paper in the paper tray for
printing check patterns.
Printing the left, right, top and bottom margin check pattern
(1) Switch the machine to the maintenance mode.
(2) On your PC, save a copy of "mediaadj_disc_BHmini13_Step.prn" to a USB flash memory or
SD card.
(3) Use "1.3.21 Printout of PRN/JPEG Files in Memory Card (Maintenance Mode 61)" in this
chapter to print test patterns.
Tip • The test patterns can also be printed by opening [Filedrgs] on your PC and dragging &
dropping the above file onto the Brother Maintenance USB Printer driver icon.
• <Models not supporting disk printing> Adjustments can also be made in
"mediaadj_BHmini13_Step.prn."
Adjusting the top, left and right margins
(1) Measure the top margin on the printed check pattern 2 and the left and right margins on the
printed check pattern 1.
The upper row of the left and right margins is for printing in 600 dpi, the middle row for
printing in 1,200 dpi, and the lower row for disc printing.
(Example) Top margin: 2.7 mm
*
If all the top, left and right margins are within the range from 2.9 to 3.1 mm, adjustment is
unnecessary. If outside the specified range, proceed to (2).
(2) If either the top, left or right margins is outside the specified range, press the [6] key twice.
The machine displays "SELECT 66?" on the LCD.
(3) Press the [Mono start] key.
The machine displays "MEDIA SENSOR ADJ" on the LCD.
(4) Press the [*] key.
<Disc printing models>
Wait for "TOP:30" to appear on the LCD and go to step (5).
<Models not supporting disc printing>
Wait for "LEFT1:30" to appear on the LCD and go to step (6).
(5) First, adjust the top margin. Enter the measured margin value (in units of 0.1 mm) multiplied by
10.
In the example on step (1) above, the measured margin value of the top margin is 2.7 mm, so
press the [2], [7] and [SET] or [OK] keys in that order.
