To check the effectiveness of the roller scraper:
1. Put on the cleaning gloves.
2. Wet a cloth with isopropanol.
3. Use the cloth to wet the bottom of the roller.
4. Turn the roller slowly with your hand. As the blade scrapes the roller,
make sure the isopropanol is spread evenly over the entire length of
the blade.
5. Inspect the roller. If it is not dry, replace the blade. (See "Replacing the
Roller Scraper" on page 33.)
6. Before returning the roller waste collector to the print block, make sure
that the pins are clean.
