Supply costs are up a hair from previous generations, but still very cheap. When using Epson's standard 1,100-page cartridges ($35 black, $30 for cyan, magenta, and yellow), ink costs for the WF-4630 are well below normal: 3.2 cents per black page, and 2.7 cents per page/per color for 11.3-cent four-color page — several cents lower than most consumer-grade inkjets and low-end lasers. The real savings begin with the $42, 2,600-page black (1.6 cents per page) and $44, 2,000-page color tanks (2.2 cents per page, per color). With those more capacious supplies, you're paying a mere 8.2 cents for a four-color page.
Epson warranties the WF-4630 for one-year, with a recommended monthly page load of 2000 pages. You may extend the warranty to two years for $40 and three years for $60. The fact that extensions are available speaks to the overall quality of construction, which is generally quite sturdy.
The WorkForce Pro WF-4630 inkjet is a sweet little multifunction that does everything well. Supply costs are distinctly better than those of similarly-priced laser printers and low-end inkjets. If you want to spend less time adding paper, the functionally-equivalent $400 WorkForce Pro WF-4640 doubles the capacity of the bottom tray to 500 sheets.
