How many pages will one 12A6835 cartridge print in the X520?
About 20,000 pages at 5% coverage (ISO/IEC 19752).

Will a compatible 12A6835 cartridge damage my X520 or void its warranty?
No. Compatible cartridges are built to OEM specifications and do not void your printer's warranty.

What does the 12A6835 cartridge replace, and is it the only toner for the X520?
The 12A6835 is the high-yield black toner cartridge for the X520 — it is not the only toner this printer takes. Lexmark also offered the standard-yield 12A6735 (about 7,500 pages) for the X520, and both cartridges fit; the 12A6835 simply lasts longer, at about 20,000 pages per cartridge. Compatible versions of both are listed on this page.
