I'm getting communication errors on my Omni 37/VX series terminal.

Unplug the power from the back of the terminal (If you have a pin pad, do NOT unplug the pin pad). Leave it unplugged for 5 seconds then plug it back in. If the terminal is still getting communication errors, please check phone line.

My Omni series terminal's paper is feeding through, but nothing is printing

Omnis use thermal paper, which only prints on one side. Make sure when you replace the paper, you have it feeding up from the bottom of the roll (like a carpet), rather than from the top. It also does not feed through the roller, simply hold a portion of the paper over the screen and close the door.

Why don't I see the deposits in my account?

Visa/MC/Discover generally take two business days to deposit, Amex takes three days.

What do I do if I get a "Call" or "Call ND" message?

Call the voice authorization center for approval and then run the transaction through the terminal as a forced sale/post authorization/offline sale.

What do I do when I get "No Line" message?

The machine is not picking up a dial tone from the phone line. Check to make sure you can hear the tone, if you can, contact your phone provider and make sure you have analog lines.

What do I do if I get "Service Not Allowed" message?

You are not currently set-up to run the card-type you are attempting to charge.

Why would my terminal issue a decline?

The cardholder does not have enough funds to cover the cost of the purchase.

Why would my terminal issue a decline Cvv2?

The 3 digit verification code from the back of the card did not match or was bypassed.

Is there any terminal maintenance I need to do?

No, but it's always safer to have the terminal plugged into a surge protector.

What do I do if my terminal does not print a receipt?

DO NOT rerun the sale until you run a detail report to see if the sale actually went through. You can also try a reprint.
