I have a Zebra series 1 that keeps throwing a mecanical error after printer the first pass yellow. It also seems like it is checking the ribbon. When ever I open the card reservior lid.

One possible reason for this issue could be a problem with the printer's ribbon sensor. The ribbon sensor is responsible for detecting the presence of a ribbon and ensuring that it is properly aligned. If the sensor is not functioning correctly, it may cause the printer to throw a mechanical error and check the ribbon whenever the card reservoir lid is opened.

Another possible cause of this issue could be a problem with the printer's motor or drive system. If there is an issue with these components, it may cause the printer to stall or throw an error message when attempting to print.

To resolve this issue, it may be necessary to perform some troubleshooting steps. First, try cleaning the printer's sensors and rollers to ensure that they are free from debris or dust. Additionally, check to make sure that the ribbon is properly loaded and aligned in the printer.

If these steps do not resolve the issue, it may be necessary to contact Zebra technical support for further assistance.
