FAQ# 2188: My cash drawer will not open with my TM-T88VI. What could be causing this?


My cash drawer will not open with my TM-T88VI. What could be causing this?


First, and foremost, check the cable connection between the cash drawer, and the printer. On the Epson TM-T88VI, there is an Ethernet port on the left hand side, that is black in color, and then in the center, on the back, there is a white port that says DK. This port is the cash drawer port. You will want to make sure that the printer is turned off when plugging the cable in.

If the cash drawer stil will not pop open, then it may be a setting within the device driver that needs to be enabled. Typically, you can check this by going into the Devices and Printers section of Control Panel. Once in there, right click on the printer driver, and select Printer Properties. From there, select the Advanced tab. Click on Printing Defaults. Click on Peripherals. Select either Start of Document or select End of Document. From the drop down box, select Cash Drawer. Try both pin 2 or pin 5 and perform an Operation Check after opening both pins, to verify which pinout you need.
