Printer will not print black ink

I had the same problem. My color cartridges printed fine, but the black did not print -- just blank. I called Cartridge World and they suggested the problem could be a clogged line. They recommended a nozzle rocket cartridge, sort of a "Drano" for print cartridges. I brought in my black cartridge and they dumped the black ink and filled it with a cleaning solution (at no cost). I placed this back into the printer and proceeded to start printing multiple pages in black in order to allow the solution to move through the lines and break up any clogs. It took about 30 pages, but the light gray color finally began to come through (it should look light gray, not black). I was told to try and use the entire cartridge before replacing with a regular black ink cartridge. Worked great!

The above suggestion was good but did not help solving my problem.
thanks for trying at least.

Hi please try these steps:::

Right-click the printer icon, and then select 'Properties'.
2. Click the 'Maintenance' tab, and then click 'Deep Cleaning'.



3. Select 'All Colors', 'Black' or 'Color' for the print head to be cleaned.





4. Read the message displayed, and then click 'OK'. The power lamp blinks and print head deep cleaning starts. (Do not perform any other operations until print head deep cleaning is complete. Print head deep cleaning takes about 1 minute.)

IF ABOVE STEPS DOESN'T WORK TRY THESE STEPS BELOW

Check ink tank vent hole The ink tank requires air to flow through it so ink can move from the reservoir to the print heads.

1. Confirm there is no orange tape across the top of the ink tank
   
   
2. If the orange tape is as shown in Figure (1), it is properly rPrinter will not print black ink - ink_tank_tape.jpg />
   
   *BCI-3's shown in this example.
   
   
3. If the orange tape is as shown in Figure (2), remove the remaining tape to the level shown in Figure (1).
   
   
4. Make sure each ink tank is snapped into the printer.
   
   IF THESE STEPS DIDNOT WORK THEN YOUR PRINTER NEEDS REPAIR(You might need to change the printer head.)
