Black &amp; white copies are often unreadable fax and computer print outs are not as bad. I have used "clean print cartridge" function repeatedly

I would suggest "cleaning the printeads" after refilling your cartridges and before printing. I'm able to do this directly from my printer, under "tools"

You can set your printer to just print in black and white only, this possibly would cut down on using the color inks.

No, it doesn't. According to tech support it mixes color in with the black to get a "richer" black. So even if you only print black and white, you are still going to have to buy color cartridges to have it run.

yes, you can do this but of course the print quality will not be as good and some of it may be difficult to read. It would be better to have the black cartridge rather than the color one because then you could print everything. The color would appear as "grayscale."

Please make sure your printer is set on black and white and color mode. In the on line instructions there is also a nozzle cleaning program you can try. If you get is to print, print a full color photo of some kind and set your printer on photo quality and print at least 5 pictures. This should clear up your issue.Thank you Freddie

Rebecca, Very hearening to hear it may not be 'just me'. The real problem seems to be that there are two modes of printing in grayscale with the HP6500. 'Black ink only' is just what it implies; grayscale rendered with the black ink cartridge only - and with perfectly good grayscale quality too. The other option: 'high quality' is actually a color dependant mode that, for some obscure reason, sprays a coat of Yellow ink onto the image area, in addition to black ink. At least that is the explanation given to me by the HP Customer Care people. The real problem lies in my inability to use the 'black ink only' option AND any 'double-sided printing' option both at the same time. You may find relief in using the 'black ink only' mode by making sure the 'double-sided printing' option is set to OFF. If you are still awake after all of this, I include my recent post to all and sundry trying to get someone out there to at least confirm that this phenomenon actually exists, and not just some bizarre short-coming in my specific situation; as HP has implied for almost a week now... In short, my opinion is that it is some bug in their software. Good Luck with your problem... ------------------------------- I need to print grayscale / black ink only AND use the double-sided printing option at the same time. Both have perfect functionality when used seperately, but the 'black ink only' grayscale option automaticaly reverts to the (color dependant) 'high quality' option as soon as any double-sided printing option is invoked. Is it just me ? I trouble you with this only after nearly a week and countless e-mails with the HP Customer Care people - and many, many hours following up on all of their fruitless directions for a fix. They will not even admit to being able to duplicate this printer preference shortcoming. I thank you in advance for any assisstance. Michael Keller

Besides using color ink to produce inferior black text when duplex printing (you can test this yourself: print text in simplex on draft; then print the same text in duplex on draft . . . This issue holds true for all quality modes), these Canon all-in-ones have one of the worst fax recognition implimentations I've ever seen. The phone you use is supposed to be directly hooked up to the printer. What I recommend doing instead is to switch the fax to answering manually. Then when you get an incoming call, if it's a fax, press "hook" on your printer, and then press either "black" or "color".

As far as I know you can't. You have to replace the ink cartridge. Even if you are out yellow and are trying to print in black and white.

I have run the color toners "low" which means less than 50 copies left per toner. The message now says color toner is low and that the printer will print in black and white. It appears that it will continue to print B&W; as long as the cartridges are left installed but empty.

I can fine no information which says that both cartridges have to be installed to print black and white prints. However, I am thinking that it is probably a good idea to have both cartridges installed. It may well be as Donald Graham suggested, though I cannot verify that.

Hmm. I was wondering what you meant so I went in to print an invoice PDF. I couldn't even get that far. Mine has an error message that says the printer is not activated (error -30). Worked on that for a bit through my printers but never did get it working. Luckily anymore I send invoices by email but I would like the option, for those oldtimers, to be able to save to PDF then fax from my computer. Saves paper!

If you are specifying "grayscale" or "black & White" in the print command, you have right to expect the printer to print it so. If you leave it to s/w to decide whether you need yellow, it won't.

It prints only in black and white - not color. I think :-) I am very happy with mine, if that's any help. FAST and efficient.

Color and black and white are two separate cartridges. If you're not printing in color, then the color won't empty.

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.

No, I think you have to scan it to your desktop or whatever and send as an attachment... It prints only in black/white, but is so fast and the cartridges last forever.
