Posted this in own thread but here is the body of text.

Happened in Maricopa County AZ.

The printer is printing a few squares on the border of the ballot light (not completely black). When waiting in line to put the ballot in the machine, the poll watchers are advising of this problem and telling people that if they have a grey square to color it in until completely black.

I tested this and the machine would not take the ballot. Went and colored it in, stood back in line, and the machine took the ballot.

One poll watcher said that this was happening to every ballot this morning and they didn’t cast a single ballot for 2 hours.

They said they’ve changed printers, toner, and cleaned the printers and the problem is still occurring 8 hours later.
