3.3 Dot plate

The dot plate is provided with this machine as standard and is used to correct the dispensing position (XY

deviation) after a nozzle is replaced. A removable ceramic plate is used as a board to dispense dots for position

correction.

The function for correcting the dispensing positions using this dot plate is called the “position correction

dispense function”. For more details on this function, refer to “4. Position correction dispense function” in

Chapter 4.

TIP

When the machine is equipped with a dot station, the dot plate is not installed in the machine since the dot station

also serve as a dot plate.

NOTE

The dot plate is only used with the “position correction dispense function” and the liquid dispensed on the dot plate

should be wiped away after use. When correcting the dot shape and liquid amount, an optional dot station will be

needed.

3.4 Dot station (option)

The dot station is used as a dummy board where the dispenser head performs predispensing, such as in the

following cases:

• Dispensing for position correction

• Performing a dot feedback to prevent a reduction in the dispensing dot size which may be caused

by a change in the remaining amount of dispensing liquid. (Dispensing amount correction)

• Predispensing during dispensing task to stabilize the first dispensing from a head that has not been in

use for a long time. (Automatic predispensing)

A roll of special paper (automatically rolled up) is used as the dummy board on which predispensing is

performed. After a syringe is replaced with a new one, the first dispensing liquid can be dispensed into a liquid

disposal cup. Predispensing is performed on the dot station with the paper held by vacuum.

NOTE

For more details on the dot station, see "5. Dot station (option)" in Chapter 4.

Negative pressure indicator

This indicator displays a negative pressure used to hold the paper by vacuum. The color of the displayed value changes

according to the negative pressure level.

Green: Negative pressure level is appropriate.

Red: Negative pressure level is not appropriate. (An error will occur during predispensing.)
