Questions about this item

Will the 40X8431 kit fit my MX710de without extra adapters?

The 40X8431 maintenance kit is listed for the MX710de and MX710dhe models, so it installs directly into those printers.

How can I confirm the 40X8431 kit is working after I install it?

After installation, run a test print; the printer should clear its maintenance alert and produce clean black laser output without streaks.

Does the 40X8431 box include toner or do I buy that separately?

The 40X8431 is a maintenance kit only — toner cartridges are not included and must be purchased separately.
