My printer will not accept a recycled color ink cartridge that I previously used!

It looks like your Photosmart 1115 printer uses an HP45 black ink cartridge and an HP78 tri-color cartridge. Some HP printers will accept re-manufactured ink carts, while other HP printers will not...just so you know. I've always bought genuine HP ink cartridges on eBay to save $$$.

If you set to black and wite it should also print pictures by the way, it does not accept grayscale because it won't be able to print in grayscale photo quality.

1 Turn on the printer and check the LCD screen for an indication of which ink cartridges are low. Note that recycled ink cartridges sometimes read "Ink low" even when they still have ink, so print a test page if you're not sure.

2 Expose the ink tray by lifting the entire LCD control panel, which is attached to the underside of the copier tray.

3 Pull out the used ink cartridge by pulling straight up from the print head,

4, insert the new cartridge into the print head and push down until you feel a click. Close the printer lid and let the printer reset the ink tray.

5 Print a test page to make sure the new ink works. If it doesn't, you may have forgotten to remove the protective tab under the cartridge.

The printer has two ink-cartridges: black and tri-color.
The black cartridge has ink left.
The tri-color cartridge has run out of 2 of the 3 colours of ink.
Buy a replacement tri-color cartridge,
and responsibly recycle the "empty" cartridge.

one ink cartridge is out of ink but...

when we try to replace one of the color ink cartridges we get this error message:

ink cartridges cannot be recognized. make sure ink cartridges are installed correctly - how do I get the printer to recognize my full ink cartridge?

if you refill the same cartridge that was in the printer
the printer would recognized the cartridge as being out off ink
you need to install another different black cartridge
the printer will identify this as a new cartridge
you then reinstall the previous cartridge back in
the printer will now recognized it as a new cartridge

Hello,

The ink cartridges included in the box are used to set up the printer. This type of ink cartridge is called a “host” cartridge. Once the printer has completed device initialization, they are marked as regular “trade” cartridges. This error only occurs if the printer has finished the device initialization process and one or more of the ink supplies inserted into the printer are a “host” supply.

Solution: The indicated ink cartridge(s) cannot be used after the device has undergone first-time setup. Once the product displays the message ' The following ink cartridges cannot be used after device initialization and must be replaced ', the designated host cartridge(s) (indicated by the color icon(s) on the display) that were rejected should be discarded or recycled and never used again. Replace the ink cartridge(s) with the appropriate “trade” ink cartridges for the HP All-in-One.

it is because the cartridges are non refillable..... they have a memory chip in them and can not be refilled except by lexmark thru their recycle center

If after you install the cartridge you get a yellow light and error message:
“The following may have run out of color. The function for
detecting the remaining ink level will be disabled since the
ink level cannot be correctly detected. If you want to
continue printing with out this function, press the printer’s
start button. Canon recommends using new genuine Canon
cartridges in order to obtain optimum quality.”

Do not click “cancel printing”. Press printer start button
to start printing. This action will bypass the ink level
detection from the recycled cartridge. It will not damage the
printer! With a recycled cartridge this action needs to be
done one time.
A full recycled cartridge ink level may not display correctly.
It may show empty.
If you want to check the ink level, you can do a “Nozzle
check” by follow the directions below:
Go to menu File select print click on “Property” click
on “Maintenance”
Click on “Nozzle check” to print out the color check.
Click on “Cartridge Alignment” to align the cartridge.
