The meter displays error code 12A6 and will not run in WOW mode.


This error indicates that the Weigh-On-The-Way® (WOW) unit is out of calibration and will not function. This can occur because:
  • Pieces of paper are stuck in the WOW unit.
  • A mail piece that is too thick was fed into the machine.
  • A user was leaning on the cover or the "skis" while feeding mail in WOW mode.
  • The machine is not level or is on an unstable table.


UPDATED: October 24, 2016
You may be able to clear the error by restarting the meter and cleaning the mail path. Follow these steps to restart safely:
  1. Turn the power off with the power switch.
  2. Wait for the display to turn off.
  3. Using a can of non-flammable canned air and working from the left side of the machine to the exit, blow onto the feed deck that the envelopes travel on.
  4. Wait one to three minutes.
  5. Turn the power switch back on.
