After a cash transaction, the cash drawer won’t pop open. What can I do?
The cash drawer is controlled by the receipt printer. To open the drawer, RMH POS sends an OPOS command to the receipt printer which sends a signal to the cash drawer. The Epson receipt printer is a network device so it must have the proper IP configuration. Follow these steps to troubleshoot:
Here are the details in each step:
Note the transaction number and exit POS.
Click OK for the error message, and complete the transaction.
Take note of the transaction number, located under the bottom of the barcode on the receipt.
Once the transaction number is noted, press the escape key to exit out of the journal. Press escape again to close POS, then click yes for the confirmation message.
Check the printer’s hardware connections.
Turn off the printer by toggling the black power switch on the front.
Check the cables at the back of the printer. The ethernet is on the right, cash drawer in the middle, and power cable on the left. Wait for 10 seconds, then turn the printer back on. The printer will blink an orange exclaimation point and have a solid blue light. Wait until a receipt prints an IP Address like this:
************************************ IP Address : 192.168.54.2x SubnetMask : 255.255.255.0 Gateway : 192.168.54.xxx DHCP : Enable ************************************
Use CheckHealth in the SetupPOS utility to test the OPOS driver.
Navigate to the start menu and search for SetupPOS.
Run the setup utility. At the UAC message, click yes.
At the main screen, double click on CashDrawer on the right.
Right click on StandardE, then click on Check Health Interactive.
Click the Start button on the window.
If the cash drawer pops, close the check health window and exit the setup utility.
Test the printer and cash drawer with a no sale in RMH.
Open POS and log in as a manager.
To test the drawer, perform a no sale by pressing F8. Once the receipt printer prints a no sale receipt, the drawer should pop.
During a transaction, I get an error that states Device TM-T88VIE error: Method ClaimDevice threw an exception. What do I do?
This issue is likely an OPOS communication issue between the printer and RMH. To resolve this issue, there are four main steps:
Here are the details in each step:
Note the transaction number and exit POS.
Click OK for the error message, and complete the transaction.
Since no receipt will print, the transaction number needs to be noted to reprint the receipt. Log in as a manager and navigate to the journal by pressing F4. The last receipt will appear in the journal. Take note of the transaction number, located under the bottom of the barcode on the receipt.
Once the transaction number is noted, press the escape key to exit out of the journal. Press escape again to close POS, then click yes for the confirmation message.
Check the printer’s hardware connections.
Turn off the printer by toggling the black power switch on the front.
Check the cables at the back of the printer. The ethernet is on the right, cash drawer in the middle, and power cable on the left. Wait for 10 seconds, then turn the printer back on. The printer will blink an orange exclaimation point and have a solid blue light. Wait until a receipt prints an IP Address like this:

How can I fix if a pin pad is not working or shows a black screen?
Pin pads can pose issues when they are powered on for extended periods of time. Here are the steps:
Follow the thick black cable at the back of the pin pad to the fan out hub.
At the pin pad hub, disconnect the small black wire connected to the hub with an L shaped barrel connector, shown on the bottom right of the diagram below:
Wait for 10 seconds, then plug the cable back in.
It takes about a minute to boot up the pin pad. Once the pin pad has finished booting, the pin pad is ready to use.
