2.3.5.1 Relationship Between Paper Thickness and Print Mode
The CPU detects a platen gap value (head adjustment lever position : Ist to 3rd position/4th to 8th position)
via the F/T sensor. With this value, the CPU
will be appropriate. (See Table 2-34.)

NOTES : 1.
Xl and X2 are values when the +35 V line is at 35 VDC. (For Xl and X2, see Figure
2-54.)
2. When the head adjustment lever is set at any of 4th to 8th position, the printing mode
becomes the copy mode, in this mode, carriage speed and printhead drive cycle change
when compared to the normal mode (lst to 3rd position).
