The Oki ES 3640 is a full function colour laser printer and copier. The drum often ends up lasting longer than the expected life cycle. Life cycle programmed into the machine is calculated by a specific page coverage around five per cent. When drums don't wear out quickly, it saves on cost to keep using the same drum. Resetting the drum count accomplishes this purpose, allowing you to use this office expense elsewhere in your organisation.
