Pro Tip
Keep a spare 55B0ZA0 imaging unit on hand in high-throughput offices; while toner cartridges replace the dry ink powder, the imaging unit wears out independently after extended print cycles and will pause printing if depleted.
Frequently Asked Questions
Can I install a 55B6X00 extra high yield cartridge if my printer originally came with a 55B6000?
Yes, the 55B6X00 cartridge fits into the same slot inside the Lexmark MS431dw as the standard 55B6000. It shares identical external dimensions but contains significantly more toner powder for longer operational cycles.
How does the 55B0ZA0 imaging unit differ from the 55B6H00 toner cartridge?
The 55B6H00 cartridge holds the toner powder, while the 55B0ZA0 imaging unit transfers that powder onto the paper using electrostatic charge. The imaging unit lasts up to 40,000 pages and requires replacement far less frequently than the toner cartridge.
Will using high-yield 55B6X00 cartridges reduce toner fading on long print runs?
High-yield cartridges maintain consistent toner density from start to finish because the internal distribution mechanism is built to handle higher page counts without degrading print output.
