1.4.7 Individual operation of each unit (Function code 18)
<Function>
This function enables you to operate the platen, carriage, sub tank, and drive frame assembly
separately. This is useful to identify the defective unit during troubleshooting and to check the
operation after any of these units is replaced.
While the function code 18 is executed, a machine error is ignored. Therefore, even if the
machine is in the error state, you can operate each unit forcibly.
<Operating procedure>
(1) Press the 1 and 8 buttons in this order in the initial state of the maintenance mode.
"PlatenPosition" is displayed on the LCD.
(2) Enter the menu number of the operation item you want to execute in accordance with the
table in the next page .
For instance, if you select the CarriagePosition menu, press the 2 button first and
then button. You can select the menu using the or button as well as numeric
buttons. In this case, display the operation item on the LCD and press the button.
(3) Then, enter the sub menu number of the operation item. If you select "HOME POSITION"
in the CartridgePosition menu, press the 1 button and then OK button. You can select the
sub menu using the or button as well as numeric buttons. In this case, display the
operation item on the LCD and press the OK button.
The Data LED starts blinking, and the selected operation starts.
To cancel the operation, press the
Cancel button. Pressing the Cancel button does not
end the function code 18 itself and return to the standby state of the function code 18, but
stops the ongoing operation. For instance, when you select "PRINT POSITION" of
CarriagePosition and press the
Cancel button during the operation, the carriage stops
while it is moving to the print position.
(4) When all the operation is finished, the Data LED is turned OFF.
(5) When you finish checking the operation and end the function code 18, be sure to turn
OFF the power or pull out the power plug. When you operate each unit individually, it
might stop at an unusual position, damaging the product. To prevent the damage, you
need to turn the power OFF and ON to return the unit to the home position.
There is another means to end the function code 18. Press the
button to display
"Really Quit?" on the LCD and press the OK button, then you can returns to the initial
state of the maintenance mode. When the head protection and machine cannot be
recognized, "PleaseWait" is displayed on the LCD.
When you returns to the initial state of the maintenance mode by displaying "Really Quit?"
and pressing
OK button, the machine cannot identify the operation state of each unit, and
therefore it cannot perform the next operation, and, in the worst case scenario, the
machine might get damaged. For this reason, there is a need to perform HOME
POSITION/INITIAL POSITION of each unit or turn the power OFF and ON to return the
unit to the original position first, and then returns to the initial state of the maintenance
mode.
