I stored the printer for a while. When I hooked it back up it says that it's out of ink(Blk) but there is ink in the cartridge.Ehat can I do? It was stored with all cartridges having ink in them.

take the black cart. out and dab on a wet paper towel, unplug printer and use q tip to clean the print head where the cartridge goes with alcohol, if that doesnt work you have a bad cartridge

There isn't a reset button, just agree with the printer and push the "OK" or Cancel button, and keep on printing. Long story made short, most ink cartridges come with pre-stamped ink levels or expiration date, that you or I can't change. That the price you pay for superior tech and why ink cost so much. I hope that helps.

some times even a new one can be faulty take it back to the shop for a replacment

Please clarify the issue. The printer should automatically switch back and forth as needed. If you want to force it to print only black, yu can do that through the printer properties, preferences, and check the tabs for an option to print only black.

One or both print cartridges are defective.Look under the "check ink" what message come.If it's BLK change black cartridge, if it's CLR change the color cartridge.If BLK and CLR change both cartridges.

The small black ink cartridge is the photo black cartridge. If you're not printing any photos that's why it is still full.

It seems like you are using incorrect printer cartridges.....

Make sure that part number on ink cartridges should be :

MK990 Cartridge, Ink, Standard, Series-9, Black CTRG,INK,STD,SERIES-9,BLK 0 1 0 Yes 1 N MK991 Cartridge, Ink, Standard, Series-9, Color CTRG,INK,STD,SERIES-9,CLR 0 1 0 Yes 1 N MK992 Cartridge, Ink, High-Yield, Series-9, Black CTRG,INK,HIYLD,SERIES-9,BLK 0 1 0 Yes 1 N MK993 Cartridge, Ink, High-Yield, Series-9, Color CTRG,INK,HIYLD,SERIES-9,CLR 0 1 0 Yes 1 N MK995 Cartridge, Ink, Series-9, Photo

pls make sure that there is no error in blk cartridge nor ther any warning symbol, ensure as well that you have installed corrctly and you can see the presence of the blk ink on your console. in other areas pls check when printing on the printer properties and select blk to identify what is the real prob.

we can start from here goodluck

bye, bye mfc...
