Changing the Memory Switches - Printer Access Method

To view or change the memory switch settings on an Epson printer, you will first need to run a self test:

• Turn the printer off
• Hold down the Feed button
• Turn the Printer back on while still holding the Feed button.

• After the self test print is complete, there should still be the error light flashing on the printer.

• Press and hold the Feed button until it prints again.

• The next page should be a short menu listing.

• Those options are the memory switch settings.

• Most options will be under the '3. Customize Value Settings' menu.

Note: Be sure to shut the printer off after setting any value, otherwise the new setting will be lost..

Printer Access - Main Menu

After the self test runs and the error light is blinking. Press the Feed button until the menu prints (>1 second)

The way the menu selection works is by pressing the Feed button the same number of times as the number next to the option, then pressing and holding the Feed an additional time after that (i.e. to select the 2nd option in the list, you would press the Feed button 2 times and then press and hold it on the third

Setting the print density

Selectable from levels 1 to 13 (70% ∼ 130%)
Setting the multi-tone print density
Selectable from levels 1 to 13 (70% ∼ 130%)
• For information about how to use the memory switch setting mode, see "Memory Switch Setting Mode"
• For detailed information about the TM-T88V Utility, see the TM-T88V Utility User’s
Manual.
• For detailed information about ESC/POS commands, see the ESC/POS Application
Programming Guide.
• Be sure to install the roll paper guide when you select the 58 mm paper width. (See
"Changing the Paper Width" )
• Once you change the paper width from 80 mm to 58 mm, you cannot change it back to
80 mm.
The print density can be set with DIP switches (2-3/2-4) or the customized value. (See
"Selecting the Print Density (DIP Switches 2-3/2-4)".) The initial setting of the
customized value is “Depends on the DIP switch settings.” If the customized value is
changed, the value set with the customized value is enabled.
• First change the print density, and then configure the Multi-tone print density.
• If you set the density too high, the contrast becomes lower. Select the density level
checking the overall tone balance of your image.

Selecting interface mode (The selectable interface is referred to as the "UB" interface.)
Selectable from: automatic selection, fixed to UB interface, or fixed to built-in USB.
Those 3 modes are described in both tables below.
For models with serial/parallel UB
For models with other UB
 

Interface selection

• Auto (interface that receives data first) (default setting)

• UIB

• USB

• UIB/Bluetooth

• Ethernet/Wi-Fi (TM-T88VI)

• No main connection I/F

The TM-T88V & TM-T88VI have two or more interfaces: a built-in USB interface and another interface selected by the customer. (The selectable interface is referred to as the "UB" or "UIB" interface.) The table below describes the modes you can set for the printer to control the dual interfaces.
