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 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.
A:AnswerHi DK32, Sorry, we do not test third-party media, so cannot guarantee the quality of printing on plastic sheets. If you try it, please use sheets that are manufactured for ink jet printers. Regards, Mark - The Epson Team.

A:AnswerHi Silivalisuz, You can scan up to 320 pages into a single PDF document using the WorkForce Pro WF-7840 and the included software. The auto document feeder holds 50 sheets, so this would require several reloads. Regards, Mark - The Epson Team.
