Label Printing Issue 追蹤

I am not sure whether this is the right forum to post this kind of question. If not,

could you refer me to another forum that deals with printing? 

 

I am printing on a Zebra ZT230 using the Bartender software and are suffering from a lot of stripes across the

labels. We can run 20 labels that are allright and then we have problems with
every second of the labels in the next batch of 50 labels.

I have attached some picture of the problem and our setup.

 

I have tried using the Zebra guidelines and i am guessing that the issue might be coming from wrinkles on the ribbon material, however i have not yet cracked the code. The quality of the ZT230 machine itself should not be the problem? 

 

Any advice or suggestions?

Yes, this is ribbon crease/wrinkle and is cause either by or a combination of physical print head alignment, platen roller, alignment, uneven print head pressure, or too much print darkness.  The software can only control the darkness, so by all means try lowering it a bit to hopefully avoid the problem.  Too much darkness with the particular consumables you have loaded can result in the ribbon melting slightly under the heat, thus deforming the substrate giving rise to ribbon wrinkle.

Thank you, Ian. :ph34r:  Much appreciated. 

I have adjusted the darkness down by 20%, which help some, but still too many failures. However, for some reason i tried to increase the speed from 2.0 to 3.0. This changed the behaviour of the printer from continuously printing to one print, small pause, one print, etc. This seems to have helped. This makes sence, since we have discovered that when we only print one label, there were no problems. 

Increasing the speed to 4.0 helped even more and the errors seems to be gone.

I´ve found that raising the print speed to 4.0 helps with the wrinkle issues on ZT230.

As you mention, Legacy Poster, the quality improves when it is print one label, small pause, print one labe, small pause, etc. 

For some label templates i have not been able to adopt this approach. Is there a way to force this behaviour in Bartender? I have been able to put an actual pause in between each page, but that requires us to press the start/pause button for each label :) 

Can i force a delay or pause between each label?

Dennis: The brief pause effect that you allude to is generally caused by the printer having to crunch through a relatively big chunk of variable data on a label by label basis.  Often this is because Windows fonts are being used from such variable data and is therefore generated as graphical data.  If you want this effect then you can try using a Windows font for variable data items, or you could disable performance features via the "Performance" tab of the "Print" dialog.
