Note 1: When the noise is heard, do the following.
• If the problem is the cleaning blade, it is not clear which station is suffering from a strange noise.
Make 10 solid copies using each color. If the problem is not corrected, dispose of the waste toner,
and put 5 g of drum cleaner lubricating agent (FG2-1694) into the cleaning assembly.
• If the problem is the side scraper, replace the side scraper, and put a small amount of drum cleaning
lubricant to the tip of the side scraper.
• If the problem is the side seal, clean the felt surface, and remove the drum cleaner.
