☛ Caution
• The factory settings are indicated in bold.
• If the robust Xon setting is turned on with selector 8, the printer sends
Xon signals at one second intervals to the connected computer until it
receives data. It is effective only if selector 7 is set to the On position
for the Xon/Xoff plus DTR setting.
