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:AnswerHello GDon. No, the Epson WorkForce Pro WF-7840 does not support printing on printable CDs or DVDs. Our Expression series printers include disc mounting trays for printable CD/DVDs. Regards, Bobby - The Epson Team.
A:AnswerHi Tom, The WorkForce Pro WF-7840's scanner works with TWAIN. You can start Epson Scan 2 from a TWAIN-compliant scanning program to select scan settings, scan, and open the scanned image in the program. Regards, Mark - The Epson Team.
A:AnswerHi Silivalisuz. No, the Epson WorkForce Pro WF-7840 must be connected to a telephone wall jack to send or receive faxes. Regards, Bobby - 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.
A:AnswerHi HandyhankTexas, The WorkForce Pro WF-7840 absolutely is compatible with your iMac, as long as it is running OS X 10.5 or later. Regards, Mark - The Epson Team.
A:AnswerNot well at all. Very light density, smears easily, dries slowly. There is no setting for transparency printing, if you talk to Epson, they will tell you that the printer does not print on transparency. Using a glossy finish paper select, the best result I could get was still unacceptable.
A:AnswerHi mag, You can print archival photos on the WF-7840 using Epson photo paper. The WF-7840 is an all-around office printer that prints sharp documents and photos. If you are interested in a dedicated photo printer with superior quality, please look into the Epson Expression line. Regards, Mark - The Epson Team.
A:AnswerHi MissT. The Epson WorkForce Pro WF-7840 can automatically scan both sides on an A3 (11" x 17") sized document in 1 pass. Regards, Bobby - The Epson Team.
A:AnswerHi wildriver, This is outside the spec of the WF-7840, so it will probably not feed properly. For the media you describe, a commercial-grade printer with a straight-through path would be more suitable. Regards, Mark - The Epson Team.
A:AnswerYou can choose to scan at various resolutions and sizes, also B&W or color. Each of these decisions will effect the size of your scanned file. The best way to work with the entire file after those decisions is using Adobe Acrobat Professional. If you need more information the Users Manual for the WF-7820/7840 is available on the Epson website.
A:AnswerHi. The Epson WorkForce WF-7840 printer was designed with an Automatic Document Feeder with a 50-sheet load capacity. Regards, Bobby - The Epson Team.
