Chapter 1 Product Overview
About the USB connector (USB-A - Device Charging, The white USB connector)
•Make sure you use the genuine cable for the tablet, smartphone, or USB device you are using.
•Charging may not be performed depending on the device's charging specifications.
•To set an optimum current value for charging the connected device, it may take several seconds
before charging starts. Charging may stop temporarily immediately after the device is
connected.
•If a device connected to the USB connector (USB-A Device Charging) has a rated power that
exceeds the rated current of the USB connector, charging the device is stopped. See "Product
Specifications" on page 118.
•The device may not be fully charged depending on its settings or usage conditions. For
example, when the device is used with the screen brightness set to its maximum, and/or with
the sleep function disabled.
•Seiko Epson Corporation assumes no responsibility for economic damages or problems arising
from failure of charging the connected device due to a failure or malfunction of the product.
•It may be hard to disconnect some types of USB cable. Do not forcibly pull the cable, or the USB
connector and USB cable may be damaged. Contact qualified service personnel if you
encounter the trouble.
•To communicate with a tablet computer via Bluetooth while charging the tablet through the
USB connector (USB-A - Device Charging) on the printer, set the "Interface selection" setting to
"Bluetooth only". For more details, see "Software Setting Mode (Customize Value Settings)" on
page 95. However, if you do so, the maximum supply current is limited up to 2.1 A for an iOS
tablet, and up to 1.5 A for an Android tablet. Charging may not be possible depending on the
tablet. Please use the tablet after testing and evaluating it adequately.
•When connecting an Android device to the USB connector (USB-A - Device Charging) for data
communication, make sure that the device satisfies the following requirements.
Requirements: The version of Android OS is 10 or later with kernel version 4.9.15 or later
However, Epson does not guarantee normal operation of all Android devices even if they satisfy
the requirements. Run some tests before actually using the device.
•If the printer is connected to a wired network, an iOS tablet connected to the printer via the USB
connector can access the network through the Lightning to USB cable. For more details, see
"Network Tethering (iOS device only) (For Device charging model/Bluetooth model)" on page
106.
