COMMAND ERROR and ink setups on late model EPSON printers
Did this article help?
"Command Error" occurs when the printer receives print data that was ripped for a different ink configuration. This error can occur on printers of the types Epson 7600, 9600, 10000 and 10600. "Command Error" appears in the display and all lights start flashing.
To clear the error, delete the job that still tries to print from the Windows and/or Best Print Manager.
Now check in your CMM datasets in the "Advanced" settings area under OUTPUT QUALITY that the correct ink setup is selected. This is the area where it really matters. (See attached screen shots)
You'll also see on the main page of your CMM dataset the option to select the ink setup. But this only refers to information stored by ProfileKeeper and should load proper profiles. It is not creating the information for the RIP output. The RIP output depends on the correct setting in the output quality window.
Please note the further information on available inksets:
- UltraChrome 7c with a photo black (standard shipping unit)
- UltraChrome 7c with a matte black
- UltraChrome 6c with 2 matte black
- PhotoDye 6c (2 black cartridges)
Same as 7600
- PhotoDye 6c
- ColorFast 6c
- PhotoDye 6c
- ColorFast 6c
- UltraChrome 6c with photo black
- UltraChrome 6c with matte black
- switching from PhotoDye to UltraChrome (or ColorFast) or back is NOT possible. You have to decide on one inkset when you load ink cartridges for the very first time. This selection will be final for the life time of the printer. If you received the wrong ink set in your shipment, contact EPSON immediately and DO NOT load it into your new printer.
All models except 10000:
- switching the black from photo to matte black or back is possible. It required a draining cartridge and takes some time and costs probably around US$100 in wasted ink during the draining process. If you need to switch frequently, consider a 2nd machine.
- to use the PhotoDye inkset you need to upgrade your Best 4.6.3 Colorproof/Screenproof to ProPack1. PhotoXposure and ARTmosphere v.4.6.3 contain already the required patch.
- the 2 7c configurations use also a light black ink (the same for both configurations), which can be replaced in the 6c 2x matte black configuration with a 2nd black cartridge if a lot of text is printed.
- for the 2 different ink configurations you have to select different printer models in your Best software. Select "Epson Stylus Pro 10000" if you use Photo-Dye inks or select "Epson Stylus Pro 10000CF" if you use ColorFast (=CF) inks.
7000 vs. 7500 / 9000 vs. 9500:
- here the difference between DYE and ARCHIVAL inks is reflected in the printer name. As with the other models switching between inksets is not possible with one exception: Epson offers an upgrade path from 9000 to 9500 (but not back).
- the inks used in 7000/9000 are the same as known from the 5000 and tend to shift fairly quickly in color and have fading issues that are usually an eliminating factor if used for color proofing.
- Epson offers a 2nd inkset for the 7000/9000 which is to our knowledge identical to the one in the 10000 and differs in an enhanced yellow and light magenta. Output is more stable, but still often not stable enough for demanding color proofing environments.
- Best recommends Epson's UltraChrome inkset for color proofing to achieve the widest gamut and the highest color stability.
- use photo black configuration for semi-matte or glossy papers
- use matte black configuration for matte or uncoated papers (works also well on newsprint)
- double matte is not a proofing configuration, but can be cost efficient for high volume text output, e.g. for newsprint.
- use photo-black for Canvas and other semi gloss or gloss coated materials
- use matte-black for water color or other high absorbent matte materials
UltraChrome inks have a wide gamut and create a very sharp and fine dot. A side effect on some printers can be a fine banding effect that is visible as very fine horizontal lines. Best software has an internal setting that overrides the print head calibration in the Epson printer. Please adjust in the ADVANCED area of your CMM dataset in the PAPER tab your target length until the fine lines disappear. Default length is 50cm/19.69". I recommend to increase/decrease by 0.1cm/0.05" several steps up and down (max. 1% ca.0.5cm/0.2"). When you found pleasing prints, you can fine adjust in 0.01 steps between your best values to optimize your print quality. After dialing in an optimal value, you can edit your paper profile using BestProfileKeeper and enter the destination value directly into the profile (use the Extended area within ProfileKeeper) so the setting doesn't get lost and is automatically applied to all CMM datasets that use this profile.
We're also working on a new algorhithm in our dithering modules that will allow to build base linearizations and therefore profiles that use a higher amount of light ink to better fill in gaps between dark droplets to hide banding effects better. Unfortunately doing so might result in a slightly decreased life expectancy of your printouts.
