HP DeskJet 3070a Manual — Setup, Troubleshooting & Maintenance Guide

1. Ensure you are using genuine HP 65 or HP 65XL cartridges
2. Check print properties and select the appropriate paper type and print quality from the Media drop-down list in Printer Actions > Set Preferences
3. Check estimated ink levels; if cartridges are low, consider replacing them
4. Align printer cartridges via Printer Actions > Maintenance Tasks > Align Ink Cartridges on the Device Services tab
5. Print a diagnostics page to review color and black boxes for streaks or missing portions
6. If diagnostics show streaks, clean cartridges automatically via Printer Actions > Maintenance Tasks > Clean Ink Cartridges

Follow these steps in order:

1. If paper is visible from the exterior, pull it out and press OK
2. If not visible, open the cartridge access door (do not touch the white encoder strip)
3. For jams toward the back, open the cleanout door and remove jammed paper
4. If paper cannot be reached, close the cartridge access door, remove all paper from the tray, rotate the printer onto its left side, slide out the paper tray, remove jammed paper, and reassemble
5. Press OK on the control panel to continue

Prevention: Do not overfill the input tray, remove printed papers frequently, ensure paper lays flat without bent edges, use consistent paper size and type, adjust paper-width guides snugly, and do not force paper forward.

1. Verify the printer is powered on and paper is in the tray
2. Check for error messages and resolve them
3. Disconnect and reconnect the USB cable
4. Verify the product is not paused: access Devices and Printers, check the Printer menu for no check marks next to "Pause Printing" or "Use Printer Offline"
5. Set as default printer: In Devices and Printers, right-click your product and select "Set as Default Printer"
6. Restart the print spooler: Open Administrative Tools > Services, right-click Print Spooler, verify Startup type is "Automatic", and click Start if not running
7. Restart your computer
8. Clear the print queue: Open Devices and Printers, double-click your product, go to Printer menu, select "Cancel all documents" or "Purge Print Document"
9. Download and run the HP Printing Diagnostic Utility for automated troubleshooting

If you receive a cartridge error:

1. Try removing and reinserting the cartridges
2. If the problem persists, clean the cartridge contacts: Open the cartridge access door, remove the cartridge indicated in the error, and wipe the four copper/gold electrical contacts on the bottom with a dry swab or lint-free cloth
3. Wipe the printhead contacts inside the printer (four copper/gold pins) with a dry swab
4. Reinstall the cartridge and close the access door
5. If the error continues, turn the printer off and on again
6. If still unresolved, replace the cartridges

Important: Do not leave cartridges outside the printer longer than 30 minutes to avoid damage to the printhead and cartridges.

Supply Upgrade Cartridge Error:

1. Remove the supply upgrade cartridge
2. Insert the original cartridge in the carriage
3. Close the access door and wait for the carriage to stop moving
4. Remove the original cartridge and replace it with the supply upgrade cartridge
5. Close the access door and wait for the carriage to stop moving
6. If you still receive an error, contact HP support
