C5800 Maintenance and things to do to prevent image problems. ITB Drums

[techandtrader]

I am new to the maintenance for these. I have learned a little about some issues. Does anyone want to list real world field problems with these? Things to plan for? 🤔

I see the ITB Blade is now FM1-r475-020 and I am going to carry a cleaning assembly gear fu2-2360. I guess these can fall off or miss being put back on with a new assembly. 😐

What else please and thanks!
