Why does grey print green?
651122
Are you sure you're really printing grey? Check the RGB values on the color you're trying to print. If all three values are not the same, or very close to the same, then it's not really grey. You may have a screen calibration problem in that case. Or it could just be a poor batch of ink. The ink I have seems to be on par with the original Epson ink I've used except for the black which, to my eyes, is much closer to black than Epson's which always looked more like a charcoal grey to me. It's possible that this black does have a color tint to it, though. It's so dark, though, that I can't see it if it's there. The Epson ink, while not quite "black", at least appears to be pretty color neutral.

I think the black is really just a very dark green. I had the same problem and returned the set.

When you decide to print, Use the <Control key>, hold it down and press P at the same time. This opens the printer dialog box. Open the printer properties or preferences, click the advanced tab. then place the dot into the greyscale. This allows only "Black Printing".

I'm pretty sure it changes to green. I haven't charged mine in a while so I'm not 100%.

It's AC current. Green is ground. If no other markings on the blacks it doesn't matter.

It did turned green for me. You could just have technical issue. Maybe seller can swap ? But over all the product is great.

I don't know the answer when you're printing full color, but when you print grey scale or B&W, you can force the printer to use black only (through the print options.)

From what I know about my printer is leave the empty color cartridge in there and it should just print black & white. At least that's what mine does.

It depends on performance you want. (Eg. concurrent users accessing files on the disk). For home usage, the green is always fine.

Yes--when the print details come up just click "GREYSCALE" P.S. On sale at Walgreens this week only for $19.99 Cheaper than buying ink! I like this little printer--although it does not have a paper tray for the output page--it works better than the $80 dollar printers@!

The pcb on mine is green as well. Not sure how it could matter though, the heatsinks cover it from top to bottom.

Go into Devices and Printers, right click on your printer and then click on "Printing Preferences". There is a tab entitled "Features" and under Color Options click the "print in greyscale". You should also be given an option to choose color, B&W;, or greyscale when you print and the prompt comes up asking how many copies you want. If you go into properties, you should be able to select the color or B&W; choice then as well.

Missing colours sounds like a clogged printhead. As for the cartridge...I don't know why

I was interested in finding out if this would be a problem, so I removed the color cartridges from my printer and was able to still print in mono. Hopefully this answers your question.

The black and color are separate cartridges so if the color goes empty, you can still print in black, one of the options in the print menu is to print in grayscale if no color ink or if you just want to conserve the color ink.

There is no gray in this set. If you can find GY alone, you could use this set and the GY separate. Otherwise you might contact the vendor and see what they might have that includes Gray - I didn't even know they had Gray cartridges!

It is a color priter, but if you set your computer settings to black and white or grayscale it will print that way.

just remove the color cartridge and answer ok ok ok, ignore warning signs of color out and print on.
