SATO GL4XXE manual After a Printhead Open fault, Online, Cause inaccurate top-of-form detection

		Unit 4: Printer Configuration
		ADVANCED MODE (TABLE 4-3)
MENU		DESCRIPTION
	Head Automatic Calibration. Allows selection of whether the printer performs a media calibration
	after a Printhead Open fault.
Head Auto-Cal
	•	Enable - factory default. Performs media calibration each time the fault condition is cleared.
Enable*
	•	Disable - does not perform media calibration when the fault has been cleared.
	Is the first menu screen of a sub-menu set within Sensor Setup of the ADVANCED MODE. The
	sub-menu to follow determines if online automatic calibration will be enabled or disabled.
SENSOR SETUP
Online Auto-Cal

Determines if automatic calibration will occur when the printer is online. Will perform Run Auto- Cal and when complete, the printer will momentarily display the Sensed Distance, then resume printing any pending jobs.

	•	Disable - factory default. Automatic calibration will not occur each time the printer is brought
Online Auto-Cal
Disable*		online.
	•	Enable - automatic calibration will occur each time the printer is brought online.

Note: This feature will not function when there is data in the buffer and when Fault Reprint of the USER MODE is enabled. This feature must also be enbled prior to printing any data.

Permits automatic compensation for any media imperfections that may affect the sensor’s ability to read reference indicators.

•Disable - factory default. When the leading edge of a gap is detected, the printer continuously looks for the leading edge of the next label and uses it as the top-of-form

	position.
Gap Windowing
	• Enable - when the leading edge of a gap is detected, the printer ignores the first 90% of the
Disable*
	gap length value specified in the Gap Length menu option. The result is that cross
	perforations or unusual media discrepancies within the gap are filtered out. This allows the
	printer to reliably detect the actual leading edge of the next label and use it as the top-of-form
	position. With this option, perforations or unusual media discrepancies within the gap can
	cause inaccurate top-of-form detection.
	Allows the actual length (height) of a gap measured in .01 inch increments to be set. The
	allowable range is 0.05 to 1.00 inches.
Gap Length
	Note: If an incorrect gap length is set, the image on the label will shift accordingly.
3 mm*
	The factory default is 0.12 inches.
	Setting determines if a calibration (Run Auto-Cal or Pwr Up Auto-Cal) will be performed while in
	the Peel-Off Media Handling mode.
	• Disable - factory default. The printer will not permit calibration and a “CANNOT CALIBRATE/
Cal in Peel Mode
	Disable Peel-Off” message will breifly display. Additionally, if PwrUp Auto-Cal is enabled, the
Disable*
	printer will not perform calibration at power up.

•Enable - Run Auto-Cal can be performed from the operator panel. If the PwrUp Auto-Cal option is enabled, calibration will be performed at power up.

	Minimum Calibrate Delta. Permits the sensor minimum threshold value that is required to detect
	the difference between the label and a gap, notch, hole or eye-mark to be changed. This allows
	bolder gaps to be used as the top-of-form while intermidiate gaps are ignored.
Min Calib Delta	Increasing the value makes the sensors less sensitive to intermidiate gaps or noise. Decreasing
020*
	the vlaue makes the sensors more sensitive for detecting gaps on low contrast media where
	there is little differnece between the label and the liner.
	The factory default is 012 with a range of 012 to 050.
