"i have other problem in this wf-c5710........ the problem is sometimes cutting the printing on text and sometimes double printing on same text "
i have the same problem too . Reinstalling driver isnt solving it. i tried all drivers , universal, postscript also different models drivers. none of them working Because its not about the driver. its about the chipless firmware. With original firmware in standart speed mode its working fine. But when we change the firmware to chipless in standart speed mode it writes double time on same text. if you change the speed mode to high quality it stops. but this time its too slow maybe 5 pages a minute, everybody complaining about it. When you make speed fastest the doubling stops but this time colors and blacks are very very faded nobody accept this colors. i think you are changing a small wrong part at the firmware. İhope you solve it because its directly affecting our business. we had to change machines with wf-6590 and there is no chipless solution for them
