What the Deuce? Blob cause?

[trakers]

Twice now a few days apart I have saw this on prints. One was on the left side of the print and the other on the right. Ideas?

The actual blob is about 1/2 x 1/4.

clean the head (with swabs!!) you have some gummy schmutz on there!

Maybe you print banner or any other material that had some loose fiber and got stuck on the printhead base!!!

Thanks all.

Any good sources for affordable access to a load of those foam swabs?

I have a few from my vendor but assume there is a better place to get them.
