Table 5.1.1 Setting of Technical Function No. 27
Note1: The luminous intensity ranking is determined by the first, second and third digits from the
right in the LED print head (i.e. in ---XX122, 122 is the luminous intensity ranking.)
Note2: When the head label of the replaced LED print head (new part) is the same as that of the
used LED print head (old part), you do not always have to set the LED print head width
by technical function No.28. (Refer to table 2.9.1, TF No.28)
