National 168 "Make Another Selection" Issue

[fdecrist]

Hello fellow vendors,

I am having an issue with one of my National 168's, which almost never give me problems. Two of my selections are not being recognized by the machine for some reason (E0 & E1). If I click the selection, it'll say "Make Another Selection". If I try to price it, it'll just skip over those two selections. I tried doing a few things but they haven't worked (replacing motors, RAM Clear & checking for proper pin connection. The last thing I can possibly think of is either the board, or a faulty tray harness.

Any ideas?

Thanks!

Sounds like a bad tray harness. Tray swapping the E tray with another and see if the problem also moves with the E tray. If so, bad harness. If not I would swap tray board to right of tray where harness plugs in

@cvending That makes sense! Thank you!

When that happens, the tray harness head isn’t making proper contact with the tray board. I’ve actually fixed the issue in a few of my machines with construction tape. The harness connects to the board, bend it towards you and tape over that position. Then go into the control panel, undo the whole row of E, in your case. As in deleting the row. Then Turn the machine off. And then back on. Then add the whole row of E back. You should be able to recalibrate those selections again. 167s are a little possessed sometimes. I never had to change any harness or motors, just really good tape to bend the harness head's position to the board. It has nothing to do with the motor. Don’t waste money. Hope that helps👍
