Trouble Shooting
NOTE 1 - Selecting USB I/O Port
When selecting USB as the interface & no connection is made, different messages may
appear on screen. For instance, "All USB interfaces in use, please delete any unused USB
printers and make sure your printer is plugged in and turned on". The problem lies with the
PC I/O ports. PC maintenance needs to be performed. Some PC corrective actions that
can be performed by the user:
1. If a “line” printer is also attached go into the printer properties & change the port to
USB002. The “line” printer likely has USB001. Since the printer has moved around
between ports it could even be USB003 or USB004.
2. If all USB I/O ports are shown as “occupied” & devices are actually connected, then a
port extender may be needed
3. Run the installer again after plugging the POS receipt printer into another USB port.
4. If problem persists see NOTE 3 below.
NOTE 2 - Printer prints, Cash Drawer Does Not Open
1. Determine if the system application program software (“SAPS”) communicates with
the printer/drawer driver by Driver Based Communications or Direct Based
Communications.
2. Driver Based Communications is handled automatically through the printer driver
which controls the opening the cash drawer. Therefore, this method should not be
causing the cash drawer to not open.
3. Direct Based Communications SAPS has Drawer Open Codes that are programmed
into the SAPS to allow the drawer to function. These Codes are in the format
expected by the system application program. The Codes need to be changed.
a. Manually enter the Cash Drawer Open Codes.
i. Try values from “Codes” column.
ii. If values from Codes column do not work, try “Alternate Codes.
b. If the Codes are fixed contact the software vendor to request that the SAPS be
changed to allow manual entry of the Printer/Cash Drawer Open Codes.
