Data validation error: the blank zone(s) left or right of the bar
code is not big enough to meet the minimum requirement.
Typically, this occurs in forms where bar codes are placed
too close to other elements, the bar code is too close to an
edge of the media, or the media's position is shifting.
The minimum quiet zone on each end of the bar code
should be ten times the minimum element width or 1/4
inch, whichever is greater. In addition, between bar
codes, the validator requires a minimum distance of 20
times the minimum element width or 1/2 inch, whichever
is greater.
1. Fix application.
2. Disable Quiet Zone in the VALIDATOR menu.
Host sent data after the printer buffer was full (serial
interface).
1. Verify that the printer matches the host serial interface
configuration settings for Data Protocol, Baud Rate,
Data Bits, Stop Bits, Parity, Data Terminal Ready, and
Request to Send.
2. Set printer serial interface parameters to match those of
the host.

Calibration values derived from Manual Calibrate were
not acceptable.
1. Run Manual Calibrate again.
Calibrate was attempted with Peel-Off Media Handling
selected.
NOTE:
You can perform Auto Calibrate in Peel-Off
mode if Cal in Peel Mode = Enable. Be prepared to catch
labels during Auto Calibrate.
1. Select another option in the Media > Handling > Media
Handling menu.
2. Enable Sensors > Calibrate > Cal in Peel Mode.
