Fuzzy Text

Text appears indistinct and difficult to
read.

There are three typical reasons for fuzzy
text, as called out in this illustration.

Top left image displays a Y-axis drum
rotation problem.

Lower left image displays the wrong drum
temperature problem.

Lower right image displays an X-axis
movement problem.

Step

Questions and Actions
