Resolving PayPoint Cash Drawer Clicking, Spontaneous Opening & Closure Failure During Printing
Audience: Public / Elo Customers, POS Technicians & IT Administrators
Article Type: Troubleshooting, Driver Update & Windows Patch Advisory
On Elo PayPoint and PayPoint Plus for Windows systems, users may experience a condition where the integrated cash drawer solenoid triggers continuously—causing the drawer to spontaneously pop open, make rapid clicking noises, and fail to latch shut while printing receipts.
This behavior is caused by a driver communication conflict introduced by certain Windows Quality Updates affecting legacy Star Micronics receipt printer drivers.
✔ Primary Resolution: Install Updated Star Micronics futurePRNT Driver
Star Micronics released an updated driver package (futurePRNT Driver v7.5.1 / v7.7.0 or newer) that permanently resolves the Windows print spooler and cash drawer kick-out conflict.

Alternative Workaround Methods
If you are temporarily unable to install the updated driver suite immediately, use one of the following interim methods:
Method 1: Re-Enumerate the USB Printer Queue
- Open Control Panel > Devices and Printers.
- Right-click the Star TSP100 / PayPoint Printer queue and select Remove device.
- Enter your Administrator credentials when prompted and confirm removal.
- Disconnect and reconnect the printer's internal USB connection (or power cycle the PayPoint terminal) to let Windows recreate a clean default printer queue.
Method 2: Roll Back the Specific Windows Update
If your Windows servicing configuration permits patch rollback, uninstall the offending update from Control Panel > Programs and Features > View Installed Updates.
- Refer to the Star Micronics Windows Update Removal Guide.
- See Elo Knowledge Article: How to Manually Uninstall Windows Updates.
Method 3: Session Switching (Admin to Local User)
- Reboot the PayPoint unit and sign into Windows under an Administrator account.
- Open the active printer queue window.
- From the Windows Start menu, switch user to the standard Local / POS User account (do not log off the Administrator account).
