Manual Calibrate - Printronix SLPA8000 User Manual

Manual Calibrate

Manual Calibrate is another method of improving the printer's media sensing
and is only used when Auto Calibrate has failed or the Gap/Mark Threshold or
Paper Out Threshold values derived from Auto Calibrate do not improve the
media sensors' gap or mark sensing capability.
To initiate Manual Calibrate, press
the CALIBRATE CTRL menu. You will then be prompted for the remaining
steps.
Example: "REMOVE RBN&MEDIA/Press Enter" or
"LOAD RBN ONLY/Press Enter" etc.
During the last stage of Manual Calibrate, the printer uses the statically
derived values, advances media, stops at the Top-of-Form position, and
momentarily displays the Sensed Distance. This process takes longer than
Auto Calibrate, and the end result is a change to the Gap/Mark Threshold,
Paper Out Threshold, and Sensed Distance values that the printer will use.
These value changes take effect immediately within the current configuration
menu.
Manual Calibrate is completed successfully when the displayed Sensed
Distance correctly matches that of the installed media. When Gap is selected,
the Sensed Distance should match the length from the trailing edge of one
gap to the trailing edge of the next gap (or one label + one gap). When Mark is
selected, the Sensed Distance should match the length from the leading edge
of one black mark to the leading edge of the next black mark.
Manual Calibrate supports label lengths up to 24 inches.
Pwr Up Auto-Cal
•
Disable (the default).
•
Enable. When the printer is first powered on, it will complete its
initialization and self-tests and then perform an Auto Calibrate. Once the
Auto Calibrate is complete, the printer will momentarily display the
Sensed Distance determined by the Auto Calibrate.
Online Auto-Cal
NOTE: Error Recover (under MEDIA CONTROL) will not function when is
enabled (see "Error Recover" on page 109).
The options for Online Auto-Cal are:
•
Disable (the default).
•
Enable. Whenever the printer is brought online, it automatically performs
an Auto Calibrate (see "Auto Calibrate" on page 113). Once the Auto
Calibrate is complete, the printer momentarily displays the Sensed
Distance determined by the Auto Calibrate and then resumes printing any
pending jobs.
NOTE: If using the Online Auto-Cal feature, you must first enable it prior to
printing any data.
