There are many reasons a drum may need to be opened—to repair an issue, clean out old ink, transition to a new color, etc. This article outlines the common processes in disassembly, testing/cleaning, and reassembly, but does not outline specific maintenance (i.e. correcting the squeegee gap, etc.)—those are separated out into their own tutorials.
Evaluation
Before opening a drum it's important to create a plan of attack—to determine how much disassembly is required. A lot of assessment can be done before opening up a drum—both how it is functioning (1) mechanically, and (2) electrically.
