Zebra 105SL label issues

We have many Zebra 105SL printers that we use everyday and they all work great when we stick one type of label in it and only print that one label type. We have one of these printers that we wanted to use in an area that they print about 4-6 different label types and we are having many issues with the printer recognizing the labels and printing correctly. I have listed some of the label types we have problems with as follows:

1" height X 2" width, with a 1/2" gap between the labels, all white label
3" height X 3" width, with a 1/2" gap between the labels, about a 1" black stripe on the left side of the label as it feed through the printer
5" height X 4" width, with a 1/8" gap between the labels, about a 1" black stripe on the left side of the label as it feed through the printer

I called Zebra technical support and they gave me a button sequence to press to get the printer to recognize the labels and this seemed to work for a while, but now we continue to have problems with it. It seems to be that the more often you change the labels, the harder it is to get it to recognize the new media placed in the printer. We have other all white labels that we use with no trouble. They seem to work every time without any special process to get the printer to recognize them.

The 1X2 labels work most of the time except recently it started to shift the print on the label. The same way as if the label format from the software was wrong. Then after changing and printing another label and then going back to this one, it will then print fine. I thought this was a problem with the label format and checked it. Nothing on this label format has changed since we set it up for this printer.

The other two labels we just have problems getting the printer to recognize the labels correctly I have performed a full media calibration and checked all the sensors. This is a brand new printer and only been in use for about 2 months.

Here is the button sequence that Zebra gave me to help it to recognize the labels:

Press “Setup/Exit” button twice

display will show:

SAVE CHANGES
ß PERMANENT à

Press “+” button 3 times

Display shows:

SAVE CHANGES
ß LOAD DEFAULTS à

Press “Next/Save” button once

Please let me know if you have any information that will help me to get this working correctly
