The Lexmark 66S0ZA0 imaging unit is a replacement imaging component for compatible monochrome laser printers. It supports the image-forming process that produces printed pages, and is listed for models including Lexmark MS632dwe, MS631dw, MX532adwe, MS531dw and MX632adwe.
Its estimated yield is up to 75,000 pages. This figure is based on approximately 5% page coverage and varies with printer series and the average number of pages per print job, so actual yield depends on printing conditions. The part number identifies this specific Lexmark imaging unit.
