Verify the Cash Drawer Interface
The printer is shipped from the factory with a cash drawer interface label on the bottom of the
printer. You should always verify that the cash drawer you are using matches the printer’s cash
drawer interface label. If there is no cash drawer label, you should remove the communications
interface card and verify the setting. See "Configuring the Cash Drawer Interface" on page 32 .
There are many vendors of cash drawers. If you are unsure what the cash drawer interface is,
contact the cash drawer vendor for more information.
If you find that the cash drawer does not match the printer, you may change the printer's cash
drawer interface configuration. If the cash drawer interface no longer matches the label on the
printer, please remove the label.
Install the new interface card
1. Slide the interface card into the printer. Make sure the interface card sits flush with the
printer. The retaining screws should also line up with the mounting holes.
2. Install the retaining screws.
3. Connect the communications interface card and any cash drawer cables.
4. Turn over the printer, and reconnect the power.
