Running Manual Calibrate - Printronix Auto ID T800 Series Administrator's Manual

To avoid this problem, increase the Threshold Range value to 60% or 70% in the Sensors > Calibrate>
Threshold Range (the default is 50%), then perform a Running Auto Calibrate page 38.
Any changes to Threshold Range will not take effect until you run an Auto Calibrate again.
This will raise the Gap/Mark threshold high enough so that the printer will not falsely use the antenna as the
gap (top-of-form).

Running Manual Calibrate

Manual Calibrate should be performed only when the values derived from Auto Calibrate fail to improve the
media sensors' ability to sense label length indicators on the installed media. Manual Calibrate is located in
the Sensors > Diagnostics section.
NOTE: Verify the Gap/Mark Sensor option (Gap, Mark, or Disable) matches the installed media.
Ensure the media sensors are horizontally positioned to permit sensing of the label length
indicators.
Ensure the Media > Handling > Print Mode option matches the media installed. Select "Direct"
for heat sensitive media (no ribbon required) or "Transfer" for thermal transfer media (ribbon
required).
If you try to do a Manual Calibrate when Peel-Off Media Handling is enabled, the LCD will
display a "CANNOT CALIBRATE" error. Before you can do a Manual Calibrate, you must
select another media handling mode.
