My dell a920 printer/scaner will not scan

When the print cartridge contacts are dirty and the printer cannot detect/communicate with print cartridge.

Clean the contact points on the cartridges with a dry, lint-free cloth.

1. Open the top cover of the printer.

2. Remove the print cartridges.

3. Clean the copper-colored contact points on the cartridges with a damp, lint-free cloth.
Use a dry, lint-free cloth to remove moisture from the contacts.

5. Insert the cartridges back into the printer.

6. Close the top cover.

7. Try printing again.

If you still cant communicate try with new cartridge .

To solve the printing problem..


# 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.
