Model DPU-414
This model features a 'Virtual' DIP switch which should be set up the first time that the printer is used. Operational settings may be required to be reset should the voltage be interupted.
CAUTION: Never turn the printer off while it is writing the new setting to memory. Always wait until 'DIP SW setting complete !!' is printed before turning the power off.
- To set the Virtual DIP switches, begin with the printer switched off and complete the following procedures:
- Slide the power switch ot ON while pressing the ON LINE button.
- Release the ON LINE button after a list of the current settings starts printing.
The printout of the current settings is followed by the prompt:
Continue ?
: Push 'On-line SW'
Write
: Push 'Paper feed SW'
- To change the DIP switch settings push the ON LINE button. To leave the settings unchanged, push the FEED button.
After pushing the ON LINE button, DIP SW1 is printed prompting the input of new settings for switch numbers 1 through 8 of DIP SW1.
Refer to the following table for the required switch settings.
Note: Always input either ON or OFF for every setting for switch numbers 1-8 because DIP SW Set mode cannot be cancelled once it is initiated.
ON can be set by pushing the ON LINE button once and OFF can be set by pushing the FEED button once. The setting is printed out after the ON LINE or FEED button is pushed to confirm the new setting.
As soon as a switch number 8 is set the printer once again prompts:
Continue ? |
: Push 'On-line SW' |
Write ? |
: Push 'Paper feed SW' |
Pushing the ON LINE button allows for DIP SW2 and DIP SW3 to be set in turn. Pushing the FEED button will exit the DIP SW setting mode.
After the FEED button id pushed the ON LINE and OFF LINE lamps alternatively blink and the new settings are written to memory. When the printer finishes writing everything to memory, 'DIP SW setting complete !!' is printed and the printer returns to ON LINE mode.
As soon as switch number 8 of DIP SW3 is set the printer writes the settings to memory regardless of which button is pushed.
