If its defective it wouldnt print or you would get an error message. If you are having quality concerns then the print head is probably clogged. Nothing you can do except replace the cartridge because it has the print head built into it.

Not printing in black


if u r used hp all in one or another then don't use duplicate ink cartidges. let make possible for u for using. boil a half glass of water, not too hot then after that drop the cotton in normal hot water & then clean the cartidge with this silly cotton on there when cartidge supply ink to printer, after some time get a wet cloth or cotton & clean it with wet clothe & adjust t=in the printer. i m sure ur cartidge will work. if ur problem not get solved then call me any time on my cellular no. +919876388918, i will try to solve ur problem with different way.
thanks alot,
sanjeev .

Still getting message empty cartidge lexmark x2650


“Lexmark does not support the refilling of its ink cartridges. Refilling the ink cartridges can cause them to leak, thus clogging or even damaging the print head. Any damage to your printer caused by refilled ink cartridges may not be covered under warranty”. Please use genuine Lexmark cartridges for best results.

Printer won't recognize new ink cartidge


Most common problems like this come from non-genuine cartridges, or refilled ones.

Refilling ink cartridges


hp74a.jpg HP #74 Cartridge Refill Instructions
Black cartridge

Instructions
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:
http://www.refillinstructions.com/black.htm 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

Printer is not printing black


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 !

Black ink cartidge


If a black cartridge will not print, with no error messages, it is probably th printhead. Clean it with proper cleaning solution. Refilled ones if done yourself or by someone else, can also have air bubbles, Try blowing down refill hole with tissue under the cartridge to stop ink spills. Also, if you press a folder non scented wipe under the cartridge firmly, you should get a solid little black line or impression. This will tell you if the ink is getting down ok. Try reprinting.

Canon MP780 didn't report out of ink and now will not pring blanck


Have you tried cleaning or aligning the heads? Were the first cartridges refills? when an ink cartridge is refilled (depending on the model) the printer needs to be tricked into thinking a "new" cartidge is being installed. You may need to check the owners manual to see if the is the case. I have had to use tape to block off certain contacts, then remove the cartidge and block off another section of contacts, then remove tape all together and re-insert the cartridge.
