I have read others who were shocked to learn that "Black Ink Only" in fact uses color ink as well. Many found out after specifically buying the product for this reason. Many have been using black only to save money only to find out that HO has misrepresented the product and I believe is also false advertising the peoduct. Does anyone know a good lawyer who wants to take on this case? We could also fight it on Twitter and Facebook.
Now it is clear why to print "Boack Ink Only" you need to have color ink available. Did not make sense until now. Forcing customers to have color ink to use "Black Ink Only" would make people pay more money on colors just to print in black. It just feels like fraud. Any others feel this way?
It is so frustrating to see companies decieve the users in this fashion.
I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details). Thank you for visiting the HP Support Forum.

HP and other printer manufacturers have different printer technologies for different needs. For inkjet printers:
Some have printheads built into the ink cartridges, typically a black and a tri-color cartridge. These printers can typically print with one or more of the colors completely empty, or even with color or black (but not both) cartridges removed. The Officejet 8040a is an example.
Other printers have separate ink supplies and replaceable printheads. An example would be the Officejet Pro 8610 printer. The printhead in these printers can be replaced if they are damaged by running the printhead with colors out. Some of these printers will allow printing with a color out, other will not. If the printer is run without ink in one or more colors the printer may be damaged, but the user may be able to recover without having to send the printer for service.
Other printers have permanent printheads. To run these without some ink in all the colors would risk causing damage to the printhead due to clogs, air ingested in the printhead or burned out printhead firing resistors. The Officejet 6700 is an example of this type of printer. For printers with fixed printheads this could require service to get the printer to print properly again when the ink is finally replaced if the printer allowed printing without one or more ink colors available.
If you never print in color a laser printer would likely be a better choice. If you occasionally print color but mostly black an IPH printer like those in the first category above may be a good choice.
