Before turning the printer off, it is recommended to send a power-off command to the printer. If you use the power-off sequence, the latest maintenance counter values are saved. (Maintenance counter values are usually saved every two minutes.) For detailed information about ESC/POS commands, see the TM-T88IV Specification (ReStick Model).
Power Switch Cover Install the power switch cover that comes with the TM-T88IV onto the printer to prevent inadvertent changing of the power switch, to prevent tampering, and to improve the appearance of the printer. To reset the printer when the power switch cover is installed, insert a long, thin object (such as the end of a paper clip) into the hole in the power switch cover and press the power switch.

Connecting the Power Supply Unit (PS-180) Use the PS-180 or an equivalent product as the power supply unit. • Always use the EPSON PS-180 or an equivalent product as the power supply unit. Using a nonstandard power supply can result in electric shock and fire.
Chapter 2 Setup Connecting the Cash Drawer Use the cash drawer handled by EPSON or your dealer. Connecting the Drawer Kick-out Cable • Specifications of drawers differ depending on makers or models. When you use a drawer other than specified, make sure its specification meets the following con- ditions.
Since the buzzer drive signal and the cash drawer drive signal are common in the printer, do not use the same connector pin numbers to output the signal for the buzzer and the cash drawer. For detailed information about ESC/POS commands, see the TM-T88IV Specification (ReStick Model).
Chapter 3 Application Development Information Application Development Information This chapter describes how to control the printer and gives information useful for printer application development. How to Control the Printer Use a driver or ESC/POS commands to control the printer. Selecting a Driver Choose one of the drivers, Advanced Printer Driver (APD) or OPOS ADK, depending on the application operating environment.
If more than 45 digits (including spaces) of the device font are printed per line, a line feed is inserted. APD for the ReStick model • Character and graphic size and paper feeding amount are smaller than when printing with the standard model TM-T88IV. • Depending on the application, characters may be printed in unexpected positions.

Chapter 4 Handling Handling This chapter describes basic handling of the printer. Installing and Replacing Roll Paper • Do not open the roll paper cover during printing. The printer may be damaged. • Do not touch the manual cutter with your hands when installing or replacing the WARNING roll paper.
Page 70
In the correct direction of the roll paper, install the roll paper. Pull out some roll paper, and close the roll paper cover. ➁ ➀ The paper will be automatically fed and cut.
Chapter 4 Handling Attaching/Removing the Connector Cover Attaching the Connector Cover Connect all the cables. The connector cover has three possible cable exits: on the right, left, and back. Position the two hooks on the connector cover so that they hook the holes on the printer case.
Removing Jammed Paper Do not touch the thermal head (See"Cleaning the Thermal Head" on page 74.) because it can be very hot after printing. CAUTION Turn off the printer and press the cover open lever to open the roll paper cover.
Page 73
Chapter 4 Handling Close the cutter cover. Open the roll paper cover and remove the jammed paper.
Cleaning the Thermal Head Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain receipt print quality. After printing, the thermal head can be very hot. Do not touch it and let it cool before you clean it. Do not damage the thermal head by touching it with your fingers or any hard object.
