Fill an old black cartridge with hot water and scan and copy something with a lot of black on it. cleaned out my black ink clog after about 12 copies. Put new ink in and it's working fine. Oh yeah, use a syring minus needle to fill lower o-ring on back of cartridge.
The product software print setting is probably designated as grayscale. Follow these steps to check this setting:
In the software application you are trying to print from, click File
, and then click Print
. The Print dialog box opens.
Make sure your printer is selected, then click Preferences
. The printer Preferences dialog box opens.
Select the Color
tab, then make sure that the Print in grayscale
option is not selected.
Step 2: Check ink levels NOTE:
you have installed a refilled or remanufactured print cartridge, or a
cartridge that has been used in another printer, the ink level indicator
will be inaccurate or unavailable.
Open the Printer Toolbox
. There are two ways to open it:
Open HP Solution Center
, select the Settings
menu, then the Print Settings
submenu, and finally the Printer Toolbox
If the HP Solution Center
method does not work, open Printers and Faxes
in the Windows Control Panel
, then right-click your printer icon and click Properties
. Click Printing Preferences
. Click the Services
tab, then the Service This Device
The Printer Toolbox
opens. Click the Estimated Ink Level
tab. A cartridge might be running out of ink even if the graphic shows
ink remaining (see the note at the start of this section). Lines or
streaks always appear in printouts when the cartridges begin to run out
of ink. Replace print cartridges that are out of ink or low on ink.
have you found a solution to your black ink problem??? I am experiencing exactly what you describe, no error messages, I have reset the printer, alinged, cleaned etc but still not a single drop of black ink but all the colours are working fine. if you know what was wrong please let me know.
