This could be a number of things.
#1 do you have DSL internet service? If so do you have a DSL filter between the jack and your terminal?
#2 Do you have digital phone service? Vontage or Comcast will cause this problem . Especially upon batching out the terminal.
#3 Check the blind dial setting within the other setup option. This option is buried, so it will require a phone call to Merchant service Provider.

If none of these work, then it is time for a new service. Place a call the Heartland Payment Systems Credit Card Processing and change your card service provider. The only card service provider that has a merchant bill of rights and field service techs (for free).

Make sure that your phone cord is plugged in and is working. You should check with your merchant services and see if anything is going wrong on their end as well.

The most common error with these terminals is that they are connected improperly. Everyone plugs the power in first then the rest of the cables. Ensure that your cables are plugged into the proper ports first. The 10-Base-T port is for internet only, the Phone icon port is for phone line, the RS232 is not used unless otherwise stated, the Calculator looking port is for pin pads only. Once the cables are properly connected reboot the terminal by unplugging the power cable for roughly 10-15 seconds then plugging the power back in. Once it starts again it should be fine. If you are running on a multiline system for phone the terminal will not dial out unless you set the prefix to dial 9 first.

I need to batch out my verifone tranz 380 machine.


if not too late.

All processor applications are different but for the most part the steps are similar.

At themain screen first print detail report. Pass word is usually 1 Alpha Alpha 66831.
Then back at the main screen hit 9 then usually 1 right after it should dial out and
settle out your transactions. Hope this helps.

Verifone Vx570 - Invalid Batch Sequence and PIN Pad Error


Well the terminal counting mechanism works in conjunction with your credit card processor. So if you forget to batch out (settle your transactions) it will give false errors. Even if you conduct a partial especially in a restaurant environment because of tips rule of thumb is always settle the sales it will save you time and a headache.

Also the pin pad error is that you have to almost always have peripherals detached before any downloads. Before detaching make sure all power is off then unplug the pin pad. Partials are only for veterens like myself that know what can be a partial download and when a full download needs to be done. Always recommend your tech to do a full download. I helped develop some of the Verifone terminals applications so taking care of these issues is a breeze.

the batch seq can be changed internally in the machine
Hit more until you see other setup. Password 1 Alpha Alpha 66831 then choose merchant by hitting the more key again. Once you choose merchants hit select on 1/1 then edit the batch number to the next one hit enter then ext save changes. RED X key to escape to main screen. This step needs to be done with no transactions.


If you still have issues don't hesitate to call me directly.

Tranz380 No Space Error


According to my B of A tech support people, your terminal is running out of memory. Call your tech support and let them walk you through it. You may need to wipe the memory of the terminal and then re-load the application.

After you print a detail report, you'll have to delete the batch and then re-enter each transaction manually and then transmit that batch. This has happened to me twice and they say it's probably due to the age of the terminal (30 yrs in my case).

Do not be discouraged by a tech-support person that doesn't know what to do. Have them ask their supervisor. The last time this happened, I had to call back and get a different tech and even then, she had to pass me off to a more senior tech, who then had to consult someone else!

Keep smiling, it's only a SMALL problem.

"Programming Err 0"


The error message "Programming Err 0" means that the terminal memory has been corrupted. The only way forward is to acknowledge the situation and reload the terminal application.

If you press the [1] and [FUNC/ENTER] key at the same time, oten the message will go away. However, you will have a terminal with no programming in it. You will need to call your processing company and get a new load.
