How to tell when my printer ink for hp deskjet 3920 has run out ? i tried to print some documents but it's not printing and two days before i printed something but the ink came out light on the paper.

well it has got to be the ink cartridge. wipe of the bottom of it and make sure black ink shows up

The HP DeskJet 6122 can print with both or only one ink cartridge installed. The printer driver includes an option to print in gray scale as a substitution for color. If you choose to print a document that has a color other than black and white with only a black cartridge installed, I recommend you select the gray scale print option. To select gray scale, select the printer properties and check the box for gray scale rather than color printing. This selection can be made either at the time a document is ready to print (ie., a one time selection, using the "Properties" box in the print options window), OR as a permenant setting using the Control Panel, Printers, HP DeskJet 6122, "Properties" window. Once changed in the general printer properties, these settings remain active anytime the HP DeskJet 6122 printer is selected to print a document.

Please check for the cartridges and try to make copies.

When you go to print check to see in your print preferences settings to see if color or black and white is checked. Could also be the specific program's print options you are using to print the pages.

Hi Anish, Have u checked the printer cartridges installed properly(i.e., Color in color door and black in black door). and also check the cabling between the system and your printer. and put the papers properly. if the problem again persists uninstall the printer driver and install the latest drives which can be downloaded from the net.

Thanks,

Check the ink level in your cartridge.

hi,
Ink-backup mode lets you continue printing with one print
cartridge when the other print cartridge has run out of ink.
Ink-backup mode allows the printer to operate using only one print cartridge. It is initiated
when a print cartridge is removed from the cradle.
Exiting Ink Backup mode
Install two print cartridges in the printer to exit ink-backup mode.


Cheers !!!!

some printers share the ink from color to black but you can select if you wants to use only black just go to printer than properies than select to use only black but you probably have to remove the empty color one

CLEAN THE BLACK INK CARTRIDGE AND THEN NEEDED REPLACE IT.

THE PROBLEM SEEMS TO BE DUE TO A CLOGGED BLACK INK CARTRIDGE.
