4.1.1 Platen Gap Adjustment
This adjustment is performed to obtain the appropriate gap between the head nozzle surface and the
platen. It must be adjusted after removing or replacing the CR guide shaft, CR unit or parallelism adjust
bushing. The specified value for the platen gap is 1.16
0.02 mm.
1.
Set the right and left parallelism adjust bushings to the middle of the adjusting range.
2.
Place the thickness gauge as illustrated below.
3.
(See the flowchart in Page 4-3.)
Turn the left parallelism adjust bushing to make the gap enough to insert a 1.14 mm-thick gauge.
Make sure that a 1.18 mm-thick gauge does not pass through. (Table 4-2 shows the directions for
turning the bushings to change the platen gap.)

4.
Apply the same procedure for the right parallelism adjust bushing.
Platen gap is adjusted using the black head as a basis. Therefore do not inset the thickness
gauge under the color head.
Open the platen gap by setting the platen gap to “+” side before shifting the CR unit.
