Cannot get black ink to work on this new machine. New ink, new printer. Any help would be appreciated. I'm working on a paper! Thanks!

Same thing just happened to my fairly new 7520 Hp.

I shut my machine first with the shut off button and then unplugged
it for about 5 minutes. Sounds like you tried this and I believe this did not work for me either so I just went into the HP official site and downloaded my printer again. Downloading your printer from their
site is easy and quick instead using the cd. It automatically removed my old printer and installed the printer again. The problem has not returned.

Another problem I just had and because I think one of my new
cartridges (yellow) is somehow damaged. I got a black line down
my pages with a note that my yellow ink is missing. Had black line only when printing and not copying. I reinserted the yellow ink and took a light damp qtip and slightly wiped the machine screen on each ink cartridge.(this screen meets the new opening from each
new cartridge. The black line left.

Hope this helps.

Did you already run the head cleaning cycle from the utility?

Your black printhead is blocked.
The printhead is deep inside the printer and has to be taken out by the expert and cleaned with the help of 'steam' and hot water. This is because not using the printer for a long time. or using low grade refill inks.
Please select new cartridge only if you are inserting a new cartridge or fully refilled cartridge. Otherwise use old cartridge option. Brother printer has a mechanical sensor and not the electronic chip in the ink cartridges.
After inserting the old used cartridge if you choose 'new cart' option it will show the "Full" ink. You can still print from the exhausted ink cart after covering the sensor in the middle by a piece of paper in emergency.

did you remember to pull the tape off the print head before you installed the new cartridge?

My new black ink cartridge wasn't working at all. I sprayed the cartridge with windex and let soak for a minute. I wiped dry with paper towel and there was black ink on my towel unlike before. The windex unclogged it and it worked like new!

ONCE PRINTE COMMAND IS GIVEN PAPER IS ROLLED IN AND THEN PAPER JAM RED LIGHT BLINKS. CAN NOT PRINT ANYTHING.BUT NOZZLE CHECK PRINT CAN BE PRINTED.

ok...start by removing the drivers from control panel, go to website and get new drivers, install them, try it again.

Remove cartridge and remove the mains from the wall.
Try cleaning the contacts with a cloth dampened WITH WATER, wipe it up with another cloth and let dry.
If your old cartridge is not working again, try with a new one, generally is the cartridge which may become damaged, not the printer... hope !

This is what worked (so far) with my Dell AIO A940 printer that wouldn't print black ink.

It worked for awhile when I chose photo/glossy paper, but then it quit printing again (see below).

PRINT, PROPERTIES, PAPER SETUP, SPECIALTY PAPER, PHOTO/GLOSSY


I got it to print, again, by putting SEVERAL papers in the feeder (instead of just 1) - there is a sensor that is supposed to automatically detect paper type, and it might not be working right, especially with one or only a couple of sheets.

Yes...it's definitely the toner cartridge.
