Solution/Explanation
OVERALL GRADE FAIL
Overall data validation failure: decodeability, percent decode,
defects, modulation, EC Min, Rmin, and/or symbol contrast.
1. Press Pause to clear the message.
2. Adjust the parameter that is causing the failure. Run a
Validator > Diagnostics > Scan Report to see which parameter
failed.
3. Lower the Validator > Grading > Overall Grade to a point where
the worst parameter grade will be above this threshold.
PAPER OUT
Load Paper
The printer does not sense media:
• Media was not installed or has run out.
• A break in media has occurred.
• Media was not routed or installed correctly.
• The media sensor is not positioned correctly.
• Media is installed correctly, but the sensor is not detecting it.
• Sensors > Control > Gap/Mark Thresh value may be set too
high and/or Sensors > Control > Paper Out Thresh may be set
too low.
• The printer detected a false PAPER OUT when changing to
Gap or Mark sensing or vice- v ersa.
1. Install media. If a break occurred, reinstall the media. Press
the PAUSE key to clear the fault message.
2. Verify the lower media sensor is properly positioned under the
media. Run Auto Calibrate to improve the ability of the sensor
to detect the installed media.
3. Check if the Gap/Mark Threshold is too high or the Paper Out
Threshold is too low. Lower the Gap/Mark Threshold or raise
the Paper Out Threshold value.
4. If using media with no gaps or black marks, perform Auto
Calibrate to establish a valid Paper Out Threshold.
5. If the printer detected a false PAPER OUT when changing to
Gap or Mark sensing or vice-versa, press the PAUSE key and
run Auto Calibrate.
PARITY ERROR
Parity error (serial interface).
1. Check your serial host interface parameter settings. If
necessary, change them so they match the settings of the
attached host.
