I have an Epson WF-7610. It prints OK when using the word processor. When I try to print with my CAD program the print is extremely light. I have set the quality in the Epson settings to the best in settings. I have set every thing I can find on the CAD print dialog which includes changing the line width. The CAD program permits changing all colors to black which is what I want. I have tried both color and black and white in the Epson settings and it does not make any difference. I had plugged print head but that is fixed. Any suggestions?
I got very light printing in some softwares until I changed the “Media Type” option setting to “Plain Paper - High”. I don’t have your particular model mine is a Epson WF-3640.
