Does it show a Flashing X for the Black?

1 Replace the Ink Cartridge that has failed.

2 If the message continues to appear, clean the electrical contacts

inside the Ink Supply Station (power OFF the Printer first).

3 If the message continues to appear after cleaning the Ink Supply
Station, replace the Ink cartridge again.

Ideally there should be two Ink Cartridges, 1 Black and 1 Color, the bright pink/reddish/etc is a sign of your Black ink running out...Also make sure you firmly seat the two inside...
If this doesn't solve the problem, your printer might either have a hardware or firmware problem...
I hope this was informative

select print black only from the print or page set-up.

No, the answer is not.
printer need all fo the ink cartridges in order to print.

Yes, u can just clean the drums , I means the rolls inside the printer, just open the printer door , then remove the cartridge , then u can use tissues with a little of alcohol to clean the rubber rolls inside .

There is a small spring that holds the ink cartridge in the ink holder. You will see it stick out from the right hand side of the ink holder where the ink cartridge slides in. If that spring isn't being held to the ink holder by two plastic tabs, (I.E. the plastic tabs are broken) the printer will never recognize the cartridge. If the printer is still under warranty I would contact HP or an authorized repair center for HP. Both the black and color ink holder has this spring. I know of no way to repair this kind of breakage.

Turn the printer off and turn it back on again and see if happens now.

If you look in the 96 (Black) cartridge loading area you might see that the retention spring has poked a hole in the circut board. I am now either trying to replace the ink cartridge holder or purchace a new printer. I have about $70.00 in new ink that I can't use now. The 2610xi worked great until the spring popped out of its holder. 

Are you using Xerox or aftermarket compatible ink stixs? I have seen aftermarket ink stixs ruin these machines. You can go to Xerox website and find information on running a process to hopefully clear up the "cyan" or blue printing problem.
