Figure 4-54 Cleaning the roller waste collector
Before replacing the covering, you can check the effectiveness of the roller
scraper—see below.
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 the next page.)
6. Before returning the roller waste collector to the print block, make sure that
the pins are clean.
