cx8400 driver invalid

Rate this Message:
Okay, this has been going on for a while now-- forums have threads fifteen pages long, and no one seems to be able to get this printer working correctly, even though it is labeled as fully supported under Gutenprint. When I plug it in with Ubuntu 8.04, it is automatically recognized and setup with the gutenprint cx8400 ppd. However, any attempt to print results in a bunch of spit out pages, sometimes with strange characters on the top line. The printer sort of works when configured as a cx3800, though it prints in a strange manner-- the alignment is far off, and the heads move rapidly back and forth in short bursts to do lines of text. The cx5800 driver works better, but colors are way off, and alignment is still not perfect.
Clearly, the printer is fully capable of working on Linux systems, with some adjustments. What can we do? I am willing to test, and from what I see, the cx8400 ppd simply needs some adjustment-- or the cx5800.

Until I can actually get my hands on a CX8400 -- or someone else steps up to fix it (which will be a lot easier in the next beta release), this won't get fixed. What does "alignment far off" really mean? In what way are the colors off? Clearly, the printer is fully capable of working on Linux systems, with some adjustments. What can we do? I am willing to test, and from what I see, the cx8400 ppd simply needs some adjustment-- or the cx5800. It isn't the PPD file; it's the printer definition that needs to be fixed.

Can you try printing a test page -- either by means of escputil -n, if that works, or by holding down the paper feed button while turning the printer on, if that doesn't work -- and sending me a high resolution scan of the output? That might help me solve this problem. -- Robert Krawitz <rlk@...> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@...

Unfortunately I am not the best test subject because my printer currently has dye ink rather than the standard Epson pigment (so some colors mix incorrectly), but I'll do a test in Windows and Linux, and send you the scan hopefully by tonight.
I cannot send any sort of print whatsoever under the cx8400 driver, so I'll do the test print under the 5800. By off-alignment... well, you'll see. ;) Thanks, Andrew Kahn

I just want to see what the pattern looks like; it hopefully will give me the answer.

Based on this recent e-mail exchange, it sounds like the nozzle check can tell you a lot about how the printer prints colors and such. Is this based on the positioning and placement of the colored lines on the page? What can you tell, precisely? Are there any web resources? I find myself somewhat intrigued. Yes, it is from the positioning and placement of the colored lines on the page. The nozzle check usually looks something like this (make sure your mailer displays in a fixed width font: (black) (cyan) (magenta) (yellow) -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ We can figure out the number of nozzles and their placement by looking at this chart. In this case, each block consists of 6 rows (vertical) and 8 small dashes (horizontally), indicating that the printer has 48 nozzles of each color, aligned. But sometimes it looks like this: (black) (cyan) (magenta) (yellow) -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ -_ In this case, it has 48 black nozzles, but only 16 each of CMY. What's more, the nozzle sets are misaligned with each other. With some printers, the nozzle sets are interleaved; some are at the base position and some are off by 1/360", and that's hard to tell from the print (I have other ways of figuring that out; print out something with horizontal lines, and if things look misaligned, then I know it's one of those printers, and I look *very* carefully at the test pattern). It's usually the photo printers that do this; I doubt (although it's not impossible) that the CX8400 does. So that's why I want to see the test pattern; hopefully it will clear things up just like that. -- Robert Krawitz <rlk@...> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@...
