I am having a problem with printing of approximately the last 5/16" of B&W prints on my HP Z3100 printer when selecting B&W and allowing the printer to manage color. I am on a PC running Vista Ultimate, and am printing through Photoshop CS4. Firmware is TR12-TR_7.0.0.3, and the driver is 61.73.361.41. I have not experienced this problem in the past using this setup.
I am printing on cut sheets, glossy paper, and selecting GE for the whole page. The paper I am using is Inkpress Baryta Warm Tone, but I tried it with some Epson Glossy and had the same result. Approximately the last 5/16" of the print is a different tone than the rest of the print. If I print the B&W image in color, and let Photoshop manage color, the problem goes away. The sheet size is 11" x 17", and the image is 9.5" x 14.5".
I have run the print head cleaning process, as well as a head alignment, but the problem persists.
Another issue I have is that if I disable the print skew check for cut sheets, the last 1/4"-3/8" of any print (B&W or color) will not print. It seems as the printer thinks it is out of paper in this case. In the above case the printer knows it has paper, as it continues to print the GE for approximately 3/4" beyond the place where ink is laid down.
All help appreciated, Mary
