ZM-Series Printer Not Calibrating With Pre-Printed Labels
Article ID: 87305071
For common calibration problems and non-preprinted applications Read More>>
The printer uses optical sensors to detect the gaps or black marks on the labels to determine the top of form. In order to achieve this detection there needs to be a clearly identified gap or black mark. Pre-printed media can cause problems with auto detection of the top of form and can result in an error or inconsistent positioning of the label or image.
How it Works
The printer performs an auto calibration when initially powered on and will feed the media using the media sensors to detect changes in light intensity and identify the top of form indicator (gap/notch or mark). The sensor used for this action is based on the LCD sensor setting of GAP/NOTCH or MARK configured in the LCD Display. The printer will identify the top of form based on the readings and then measure the label length completing the auto calibration process. If the sensor encounters excessive pre-print the auto calibration could become inconsistent or ineffective.
Common Issues and Resolutions
** If you are using Mark Media you must use the Mark Sensor. To identify the Mark Sensor click here. The Mark Sensor is not moveable so if it is encountering preprint you may have to print a Media Sensor Profile and work with tech support to determine if there are adjustments that can be made to the sensitivity that will allow the media to work reliably.
*** There can be problems encountered if the amount of light varies greatly due to the print on the label. Reliability can be achieved if the sensor can be positioned in a location where there is minimal pre-print.
