The 7000E calculates worked and keeps track of all totals per card. If E-30 is displayed when inserting a card, there could be debris in the card slot preventing the printer motor or print sensor from activating to print on the card. This could also occur when the ribbon is not seated correctly. To correct the problem:
- Remove the ribbon.
- Make sure there is no timecard or debris jammed in the card slot.
- Reinsert the ribbon.
If the problem persists, the 7000E must be repaired
