Why does the HP7520 need a 'special' black photo cartridge to print photos? None of the other printers I have owned have needed this.

The HP7520 needs a "special" black photo cartridge to print photos because using everyday ink will not be enough to print as many as 1 photo before drying up. Especially when printing 8.5 in x 11 or a few 4x6 on a single glossy paper before having to go out and replace the everyday ink.

If your printer has slots for 5 colors, one of those is for the black photo cartridge because photos require all 5.

The cartridge is actually a gray ink to help with shading in photos and graphics.http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01839024&cc;=us&dlc;=en&lc;=en&j;umpid=reg_R1002_USEN

No, if any of the color cartridges are empty it doesn't print black (as in text). It doesn't print anything. p.s. Just happened to notice the black print option on the actually printer, and tried it out (the printing option is the only one that doesn't seem to respond to this option) but copying certainly did. Sorry for the incomplete answer.

Your Cannon printer will not print if any of the ink cartridges are empty. I know it does not make sense but it was just built that way. I think they make more money on the ink than they do on the printer.

The one thing I love about the HP F380 was that if the color runs out, I CAN STILL PRINT WITH BLACK ! ... Many printers will not print If one cartridge is out (even I only want to print in B&W;)

I have a HP Photosmart 5520; the black worked but the others shut down the printer.It said they were start up cartriges and could not be used again.

I used the black 125 with some success. Upon trying the color carriages , the printer Epson Nx420 refused all my attempts to print anything. I may have damaged the printer. My solution: It is less expensive to junk the printer than to repair it. I will purchase a new printer and chalk up my loss to experience.

Once the photo ink runs out you will get an error message stating it. This same error message will not allow you to print until it is corrected (by replacing the empty cartridge with a refilled one). So in conclusion you will need all 5 cartridges for printer to work.

I have an HP 7525. They didn't work because the 'chip' was not right. HP wants customers to use their ink only. Use your original cartridge and have it refilled. Costco here does that. Also, there are independent dealers who sell HP used cartridges that are refilled and work just fine. For these dealers take your printer into their store, buy their refills or have your own refilled, and make sure the printer works at the store. The first time I used HouseOfToners they worked. The second time they didn't.

The printer comes with a coloured ink cartridge, but it doesn't last for long. The black was the first to run, so a new cartridge had to be bought.

why won't my hp 6500 print in black? It is a new cartridge that worked previously. I've tried taking out all the cartriges and cleaning them...turning it off and on...unplugging it etc... Any suggestions?

Reading customer elsewhere and on Hp support forum, I discovered that the printer will not print in black if any of the color cartridges is out of ink - all cartridges must have ink for this printer to work. See HP Support Forum response here : http://tinyurl.com/n2f32uy .

Ok 1st of all the reason that you have 2 black carts. is because 1 is for regular printing and the other is for photos. Amazon has'em. Jus be sure to look for the "XL"

What type of Cannon printer do you have? I have a Cannon Pixma and can only use the Cannon CL241 for color and the black ink is: PG 240. I have found through my own experience that I cannot use other cartridges and unfortunately most stores do not carry those. I have to order them online and find the best price through Amazon. They are generally pretty good about shipping out quickly and these cartridges are not like HP where you get down 3/4 of the way and will no longer work. These cartridges from Cannon that I use will literally use every last drop and show as if they are completely empty... yet keep on printing. What type of Cannon printer do you have?

I haven't set up the printer yet. But I have not seen anything that suggests I need a specific type of printer. I will update if I find out something different.

Thanks for getting back to me. My problem is that the small one is the one that is getting empty, and the big one is still as full as when I first bought the printer. I print mostly documents, but don't know how to force the printer to use the big black cartridge. I am thinking of trying selecting "grayscale" more often, to see if that starts drawing down on the big cartridge. I have previously just selected color printing, even if doing only black and white documents.Again, thanks for answering my cry in the wilderness.Cheers!

I have only used the black cartridge to date. I am not qualified to rate the others

I have the same problem. I am forever buying new black. The color lasts a bit longer. I keep an extra black around all the time. I bought a Kodak printer when my old HP died. I wish I had never made that purchase. $$ $$ $$....
