HP t45 won't print after I replace ink cartridge

I replaced my inkjet cartridges with compatible refills and the colors DO print but the BLACK will NOT. I even tried to realign and even that won't come in clear for me to read, much less make necessary adjustments.

This is also my business FAX too. What steps did I miss that I could take to fix this? I need my fax and printer.....

Please Help me.

Try original cartiages, that one could have something on it or be missing a contact.

The printer won't print. It says replace the color ink cartridge. All I want to do is print black and white.

You can only use the black ink cartridge without the color ink. But no need to replace them in your printer.
When you print just choose black and white for the printed text must be black not colored. But if you still received such notification...just try to replace the color ink cartridge to continue printing
Note: As per my experience. printer with exclusive black ink alone will damage the printer easily due to unbalance printing of ink

Black printer ink in HP Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

Is it possible to use non HP ink in ths printer? Tried using "remanufactured ink", and concluded that this printer may be programed to block the use of NON HP INK.

It is always recommended to use genuine HP cartridges.
As if we will use the non HP or refilled cartridges, it will reduce the life of the printer.
And we will get an error "cartridge problem".
Plaese use the below cartridges, which are compatible with this printer.

Unable to print with new ink carts

Usually, that message means that your cartridge is dead. Try removing it, clean the electric contacts on it and the ones on the cartridge carrier. Put it back in. If that doesn't help, you will need to buy a new color cartridge.
If you do not have a replacement cartridge, you can still print in, what HP calls "ink backup mode". Simply remove the problem cartridge, and print with the remaining one, in this case, the black one.
  • If you remove the tri-color cartridge, printouts will be in grayscale.

Ink cartridge light keeps blinking

you need to print only in black if that is all the ink you have, and also you need to remove the color cartridge as it still registers in the printer as able to be used, although it is empty or near so. Did you remove the tape over the print head fron the new ink cartridge? Do a print head alignment, or use the toolbox icon to tell the printer that you just replaced the cartridge. Some HP models chip the ink cartridges so even a refill wont register as a full tank and the printer wont print. chip needs to be reset (difficult) or just replaced with a new cartridge.

Refilling ink cartridges

hp74a.jpg HP #74 Cartridge Refill Instructions
Black cartridge

1. Put the cartridge on some paper towels in an area where you can tolerate a spill.
2. Peal off the top label. hp74b.jpg
3. Fill the syringe with 20ml. of black ink.
4. Very S-L-O-W-L-Y inject ink into any hole (they all go to the same sponge, HP just used the same color mold for the black ink cartridges).
5. When finished, replace the top label or leave it off (it will make no difference in the printing).
6. Replace the cartridge and run 1 - 3 cleaning cycles as per printer instructions.
Or print the following pages: for Black

For best results, leave cartridge in printer for 8 hours after refilling so the ink can saturate the entire sponge.
A Refill Kit should include Ink plus the following:
One 30cc Syringe
