A:AnswerHello Erid. Unfortunately, we have not tested the WF-7840 with transfer paper, so we cannot guarantee print functionality. We recommend reaching out to the paper manufacturer to confirm compatibility, as this printer uses pigment-based inks. Regards, Kevin- The Epson Team.

A:AnswerHi RoxyElaine, Using the rear feed tray, the WorkForce Pro WF-7840 is rated for 68 lb. paper. This includes double-sided printing. The rating was developed using Epson-brand paper, which is specifically designed for Epson printers, so third-party paper may not feed as well. The ADF can hold 50 11" x 17" sheets at a time. Regards, Mark - The Epson Team.
A:AnswerHi Bon, Unfortunately, we cannot test the WorkForce Pro WF-7840 with all third-party paper types, so cannot guarantee the print quality. To see a list of Epson paper types know to be compatible, visit the Epson support site for the WF-7840. Regards, Mark - The Epson Team.
A:AnswerHi MARC, We cannot test all third-party media in the WorkForce Pro WF-7840 so cannot guarantee that it will work, or have acceptable quality.
