Table 13. LCD Message Troubleshooting
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
from Advanced Gap or Advanced Notch 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. If Advanced Gap or Advanced Notch is
selected, verify the upper media sensor is positioned
above the lower media sensor. 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 from Advanced Gap or Advanced Notch to
Gap or Mark sensing or vice-versa, press the PAUSE
key and run Auto Calibrate.
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.
Data validation failure: percent decode. The validator
detected gross inconsistencies within the height of the bar
code. These types of failures are likely attributed to large
blemishes within the bar code, caused by ribbon wrinkle or
debris on media.
1. Check for a wrinkled ribbon or debris on media. Roll
wrinkled area onto take-up spindle.
2. Adjust the printhead pressure blocks.
3. Modify Media > Image > Print Intensity or Media >
Speed > Print Speed.
