Hi,

Our DTG printer just started printing 4 straight vertical lines of yellow, red, blue, and black ink on every shirt graphic we print. We have cleaned the print head about 5-6 times, turned off the printer a few times, tried printing different graphics, tried printing on both light and dark shirts... the lines still show up no matter what.

Any help on how to get them to stop? It is not part of the graphic at all. The problem just started today for no reason. I will try to post a picture of it.. It's not too noticeable, but it's noticeable enough to not be good on a paid order of shirts.

Thanks,
Sumati

The most common cause of this is the carriage motor gear being dirty. The gear drives the bet that moves the print head back and forth. Take a little pick and some windex and carefully clean out the grooves in the gear. Over time dirt gets in the grooves. The belt has very thin cogs which sit in the grooves. If there is dirt in the grroves it will cause the belt to skip.

You should also, of course, make sure that your encoder strip is clean. Make sure to always clean it towards the spring, never away from it. It is a very good idea to keep a new encoder strip on your shelf. If there is any question on the old encoder strip change out to a new one to see if your problem goes away. It's cheap insurance to keep around.
