Photosmart C5280. Instructions on photo cartridge 348 say remove both black and colour cartridges, then install photo cartridge in right hand cartridge holder. Printer screen then tells me to install colour cartridge in left hand cartridge holder. Surely I don't need both, do I?

your printer's black ink or the black cartridge is already empty, you need to replace it. Also the settings is not set properly.

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.

To see which color is having an issue, go to printer control panel and select "settings" > Tools> Print report> Print Quality report. When the page prints out, you will see which color is the problem. After you have figured that out, make sure the problem is not with the cartridge.
If you see lines or missing colors, clean the printhead by removing it from printer(open cover, lift gray latch on the right side of the cartridges, remove cartridges and the printhead will easily slip out by pulling up)
then soak the printhead in half inch deep amount of window cleaning solution. Preferably warm. Let soak at least 3 hours. Dry out the printhead and wipe rear conacts from moisture and dirt. Reinstall into printer and see the results.

Open the printer and remove the ink. Clean around the ink carriage and the under the ink with alcohol and a cotton swab. Pay special attention to areas with copper contacts. Keep in mind too that some printers will not print, even with full ink, if the exact type of ink it expected you to have installed is not right. Double check that the ink is correct against the manual or written instructions inside the printer using the number not the shape or color of the cartridge. Not every cartridge that fits the printer necessarily works.

I kept having the same problem as what was experienced by gobigforgod. What should I do ? Pls help.

# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.
1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.
# Reinstall the cartridges, making sure you snap them correctly into the printer.
then try to print if the alignment fails then you need to change the cart in the
printer if its original hp new cart then get replaced .....

Good luck..
