What to know before buying

Listing details to confirm

The listing calls the connections Ethernet, USB and Wi-Fi, but its feature text mentions wireless network and USB only. Confirm Ethernet availability for the specific listing if it is essential. The claimed three years of included ink is conditional on usage, which is not defined. The listed scanner resolution has no units, and the 128 MB field is labelled storage rather than memory. Confirm these details against the selected configuration.

Who is it for?

A good fit for

Home-office or small-office users who want colour printing, copying and scanning in one device.
People printing two-sided documents or multi-page originals and who can use the automatic duplex function and ADF.
Frequent printers interested in refillable ink tanks and mobile or cloud workflows.

Less suited to

Buyers who require confirmed Ethernet connectivity or a clearly specified scanner resolution before purchase.
Users who need a stated, guaranteed in-box ink duration for a particular print volume.
