SOURCE: Not printing after color cartridge ran out - new black cartridge installed.

Yes, this printer has fixed printheads and must have ink in each color to prevent damage to the printheads. Even when printing black only each color is spit in the servicing area to keep the printhead unclogged.

SOURCE: Won't print unless all ink cartridges have ink.

Try changing it in the properties section under device settings
or go to color management if you have it and change the setting to black only,.

SOURCE: Black color will not print. Installed a new black

Ink is a lubricant for the print heads. Some color ink is used even if you only print in black or vice-versa. If you printed with a color missing, you could destroy that print head from the friction of running without ink to lubricate it. That's why most printers won't allow you to print with a color missing even if you aren't using it.

If you allow a color to go empty, the residual ink in the head could clog and become permanently blocked. You would never be able to print that color again. So always replace ink cartridges as soon as they are empty.

Leaving your printer on takes very little power. Every so often the printer sends a signal to cycle the ink in the heads so it doesn't clog. If you turn your printer off, the next time you turn it on it will do a cleaning which wastes a lot of ink. The excess ink is soaked up by the waste pad beneath the printer. When the waste pad is full, the printer stops working. Unless you want to spend more than the cost of the printer or waste a lot of time on a messy cleanup you will end up throwing the printer out. So shutting it off actually shortens its life.

If you leave the printer off for extended periods of time, the ink in the heads will clog and you will have to throw the printer away. Someone I know with a Canon (though this can happen with any inkjet) had to have the heads replaced twice within the first few months before the Canon tech told her to stop turning it off. Since then it has worked perfectly for over a year.

How to clear blocked print heads:
-leave the printer on for a day
-run several head cleanings and print the nozzle check pattern
-if that doesn't fix it, remove the cartridge(s) from the blocked head and drop alcohol where the ink enters the printer.
-reinsert the cartridges
-run one head cleaning
-wait about an hour then run some head cleanings.
-dip the print heads in Isopropyl Alcohol overnight, which you can buy from chemist
-if that still doesn't work, your heads may be clogged to the point where they need repair or replacement, which will probably cost more than a new printer.

Mg7120 won't print black on paper,but will print pictures with black just fine


It looks like you may have 2 black ink cartridges; one for black-and-white printing, and one for color printing. The larger one may have clogged nozzles. Run a cleaning cycle several times, and see if that solves it.
Other options which would be entirely at your own risk:
1. Dabbing the print nozzle head with warm water on a cotton swab.
2. As above with a mild solution of rubbing alcohol.
3. Soaking the print head overnight.
4. Applying vacuum to the print head.

Is there a charge. I have a canon mg2520 and was printing and it stopped. I find I am out of colored ink. Can you not print if colored is out can't you print just black or grayscale.


No charge for information Sandra

My Canon MG7120 recently ran out of one colour and continued to print, albeit in strange colours. Printers are getting cleverer and it would surprise me if they make them so you can't use them if they are empty.

Try removing all the cartridges. Then unplugging from the wall, count to 20, plug back in, switch on and when all the start up activity stops, replace the tanks.

How to change the ink cartridge


Follow these instructions when you need to replace print cartridges.

• Everyday printing: Use a black cartridge along with a tri-color cartridge.
• Color photos: Use a photo cartridge along with a tri-color cartridge.
To replace the print cartridges
1. Make sure the HP All-in-One is on.
CAUTION: If the HP All-in-One is off when you open the print cartridge door to
access the print cartridges, the HP All-in-One will not release the cartridges for
changing. You might damage the HP All-in-One if the print cartridges are not
docked safely when you try to remove them.
2. Make sure you have letter or A4 unused plain white paper loaded in the input tray.
3. Open the print cartridge door.
The print carriage moves to the far right side of the HP All-in-One.
4. Wait until the print carriage is idle and silent, and then lightly press down on a print
cartridge to release it.
If you are replacing the tri-color print cartridge, remove the print cartridge from the
slot on the left.
If you are replacing the black or photo print cartridge, remove the print cartridge from
the slot on the right.
1 Print cartridge slot for the tri-color print cartridge
2 Print cartridge slot for the black and photo print cartridges
5. Pull the print cartridge towards you out of its slot.
6. If you are removing the black print cartridge in order to install the photo print cartridge,
store the black print cartridge in the print cartridge protector or an airtight plastic
container.
7. Remove the new print cartridge from its packaging and, being careful to touch only
the black plastic, gently remove the plastic tape by using the pink pull tab.
1 Copper-colored contacts
2 Plastic tape with pink pull tab (must be removed before installing)
3 Ink nozzles under tape
CAUTION: Do not touch the copper-colored contacts or ink nozzles. Also, do
not re-tape the print cartridges. Doing so can result in clogs, ink failure, and bad
electrical connections.
8. Hold the print cartridge with the HP logo on top, and insert the new print cartridge into
the empty cartridge slot. Make sure you push the print cartridge in firmly until it snaps
into place.
If you are installing the tri-color print cartridge, slide it into the left slot.
If you are installing a black or photo print cartridge, slide it into the right slot.
9. Close the print cartridge door.greatcir.png

Printer will not print dut to other color cartige. being empty.


The color cartridges print text that appears black by mixing the three primary colors (cyan, magenta, and yellow) to make composite black. To achieve a realistic black, large quantities of colored ink are used. Because black cartridges use much less ink to create a similar shade of black, they print more pages in black than the color cartridge.
If the color cartridges on the printer are next to empty, you will not be able to get perfect prints at all.

Please have the cartridges replaced to do the printing jobs again.

The color cartridge runs out very quickly even though I rarely use it. I make sure to print in black and white, and I manually choose the option "Use Black Cartridge only" but the color cartridge runs out...


Printer manufacturers design their printers to print some color mixed in with the black when you are only printing black. That is why your color cartridge is running out when you only print black and why it prints "weird colors" when the color cartridge is empty. Printer manufacturers sell the printers at a loss and make up the profit on the cartridges.

Lexmark X1100 printer will not print black


I came up with a work around for printing black.

I changed the black cartridge with the color cartridge.
Then when I have a letter to print, I change change (or write) the letter text to yellow, red or blue.
Then I can print out a letter.

By printing the text as yellow, red or blue the cartridge will try to print with only 1 color, but will print out black.

If you do not use one of these primary printing colors the out put will be unusable.

I can not of course print out pictures.
