I'm at a crossroads and want advice from you if you have faced this and seen results. I've replaced the Piezo inks with Epson to test the machine and its banding problem. With Piezo inks, one nozzle misfired continually for several weeks. With the Epson inks installed, all nozzles fired cleanly; With Piezo inks installed, banding occurred on all papers With the Epson inks installed, printing through the Piezo interface, banding was evident but reduced; Printing a measured 20" line on 23 inch paper using Epson inks and Piezo driver. The line measured 20 1/8 inches, which Dan Culbertson equates with accuracy based on the printer's use of Japanese measurements on the vertical plane. I infer this to mean the printer's transport system is working accurately. The line printed with no banding but was printed on a paper that doesn't accept Piezo inks so no banding comparison is possible. To test the banding 'apples to apples' I printed an image for direct comparison. The original was printed on Epson Photo Paper with Piezo inks. The comparison image was printed on Epson Photo Paper using Epson inks and the Piezo driver. All on the 3000. The results: The image printed with Piezo inks show what I have to call 'micro' banding. I describe this as very thin white lines equally separated by about 1/32 inch seen through an 8x loupe and not visible to the naked eye. This banding differs considerably from the original Piezo print (with one blocked nozzle) which showed a combination of consistent banding at about 1/16th inch plus another banding pattern at about 1/8th inch, probably caused by the blocked nozzle, all clearly visible to the naked eye. Under the 8x loupe, the Piezo print also showed a crossing pattern, which combined with the banding made the image look like it was comprised of 'chex' cereal (take your pick...rice or corn). The printer is still under warranty. Should I take it to Epson and request they check it out or run the cleaning cycle and re-insert the Piezo carts? If it is checked out, what would be the most accurate complaint that could lead to a reasonable repair? Ironically those large dots produced with the Epson inks I used to fear so much are starting to look a helluva lot better than the banding. I like the solidity of the printer and would like to find a way to make it work. However, time down is money lost and after this experience Piezo and the 3000 may turn out to be too good to be true. Thanks for listening.
