Epson EcoTank L6390 all-in-one printer, colour inkjet, A4, fax, Wi-Fi

Many public bodies, insurers and clinics still send documents by fax. The L6390 has a fax built in, so there is no need for a separate fax machine on the desk. That is the main difference from the L6360 in the same series, which has no fax: the other specifications in the supplier data are the same for both models.

The printer uses four inks: black, cyan, yellow and magenta. With this CMYK scheme it can print crisp black text as well as colour charts, presentations and photos. Ink is poured from bottles into built-in tanks rather than swapped as cartridges; the codes and yields of the specific bottles are not stated in the manufacturer data here.

The two-sided printing function cuts paper use on longer contracts, reports and school work and keeps folders slimmer. The maximum print size is A4, the standard office paper that takes letters, invoices, forms and most everyday documents. Printing on both sides also helps when a document has to be carried along or sent by post.

Over the wireless connection every computer and smartphone on the network can print to it, so the device can be placed wherever suits. Scanning is in colour: stamped contracts, colour forms and photos reach the file with every shade intact and can be archived or sent by email.

Entrepreneurs with a home office who need a printer, scanner and fax in one device; accountants, doctors or lawyers whose partners still use fax; small offices that share a printer over Wi-Fi; and families who want colour printing without swapping cartridges.
