A:AnswerThis depends on your network configuration. The router is serving both the 2.4 GHz and 5 GHz frequencies so this printer should exist on the same network as your other devices as long as you are not employing AP isolation, VLANs, etc.
A:AnswerThe depth is 18” but it goes to 23” with the #2 tray installed with 11 x 24 paper. If you want to use the back feed tray for paper it will be even more.
A:AnswerI have both the 7840 at the ES-580W, test set was a 4-page color document, 300 DPI scanned to emailed PDF:
Epson 7840, Simplex Scan: 35 Seconds
Epson 7840, Duplex Scan: 78 Seconds
ES-580W, Duplex Scan: 9 Seconds
I would not rely on this machine if I needed a lot of scans, the ES-580W is an excellent machine.

A:AnswerHello rickmilton2. Epson provides information in the User's Guide to help address issues with loading ink cartridges. Refer to the "Replacing Ink Cartridges and Maintenance Boxes" section, page 267, for more information. Regards, Bobby - The Epson Team.
A:AnswerHi BobPin, Drivers for the WorkForce Pro WF-7840 are available for download on the Epson support site. The WF-7840 includes a full set of cartridges in the box. A small amount of ink is used to prime the printer and the remainder is available for printing. You can scan 11" x 17" paper using the auto document feeder or by placing documents directly on the scan glass. If you want to connect to a computer using USB rather than wireless, you will need a standard Type-A to Type-B USB cable. Regards, Mark - The Epson Team.
A:AnswerHi JC, You can scan multiple pages to a single PDF. You can load 50 Letter-size sheets in the auto document feeder for a 50 page PDF. Regards, Mark - The Epson Team.
A:AnswerHi ja, The WorkForce Pro WF-7840 does not have an SD slot, but it does have a USB port on the front for a USB flash drive. Regards, Mark - The Epson Team.
A:AnswerHi HankinCT, Sorry, the combination of settings you expect may smear the edges of the print as it turns over to print the back side. If you print the first side then manually flip the paper to print the second side it will work. Regards, Mark - The Epson Team.
