I have a HP Officejet 6500 wireless printer that will no longer print with the black cartridge. The color cartidges all work as advertized. This is the second time in as many months that this printer has stopped printing black ink. The cartridge is a HP920XL. The cartrige is full and vented properly. The printhead is new and I have perforned the cleaning funtion many times. I have also perforned a hard reset with no results. As stated earlier this is the second time I have had this problem. I used a procedure last tme that worked but I cannot remember ho I fixed the problem. The fix had somthing to do involving tne number 3 on the printer keybord.
If anyone is familiar with this solution I would appreciate any help.
