The USB power-saving function is valid only when the USB interface communication
condition is set to the vendor-defined class and the system configuration is set so that the
USB driver can support the USB power-saving function.
This function is enabled only when Receive buffer capacity is set to 4KB.
You can use the paper near-end sensor only when you install the printer horizontally.
When you install the printer vertically or hang it on a wall, be sure to disable the paper
near-end sensor. Otherwise false detection occur.
You may need to adjust the paper near-end sensor. For information about how to adjust
it, see
"Adjusting the Paper Near-End Sensor" on page 39.
