Calibrate Sensor - Manual Setup

This method of calibrating the sensors is usually used only when the Auto Calibrate methods fail to
reliably detect TOF (Top of Form) and/or calculate an actual Paper Out condition. This method is
reserved for unusual media with holes or preprinted images that may trick the sensors in seeing
them as a Black Mark or Gap affecting TOF.
Install desired media in the printer and close the media cover.
Select the Media Type (GAP, Black Mark Continuous or Auto Selection) located to the right of the
Manual Setup.
Select Calibrate, an instruction prompt will appear under the Manual Setup.
Example: Put liner please (user must pull media out until liner gap is detected) then press Next.
Followed by: Put label please (user must pull media out until label is detected) then press Next.
Followed by: Calibration is complete or Can't Calibrate
If Calibration was complete, the following will display:
Example: Label Reading 388
Gap Reading 950
Press the M4L Control Panel Feed key - the printer should advance one label and stop with the
Gap or Mark at the Tear Bar.
IMPORTANT - When a new media type is used for the first time, it is recommended that after a
Manual Setup Calibrate, you remove the media and close the media cover to verify that the printer
will detect an actual paper out and display a "No Paper" fault message.
New Calibration values are automatically saved to the printer and will remain after cycling printer
power.
