How to Replace an Empty Ink Cartridge in the HP Officejet 8702 All-in-One series Printer – an Illustrated Tutorial in 7 Steps

Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. HP often designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed.

HP recommends that you use original HP ink cartridges. XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print at least double the pages of a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.

You can check the estimated ink levels from the printer software or from the printer control panel. The icon below displays the estimated ink levels. Ink level alerts and indicators provide estimates for planning purposes only. When you receive a low-ink alert, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until you are prompted to do so. HP recommends that you replace any missing cartridges as soon as possible to avoid print quality issues and possible extra ink usage or damage to the ink system. Never turn off the printer when ink cartridges are missing.

You can align the printhead from the printer software and from the printer display.

How to Replace the Battery in the FireX Smoke Alarm PADC240 – an Illustrated Tutorial in 19 Steps

Hazards
More accidents happen at home than anywhere else. Replacing the battery of a smoke detector is not without hazards. Make sure you know what you’re doing. The FireX smoke alarm PADC240 is mains-powered and connected to your 110 volt or 220 volt home electrical system. The 9 volt battery only serves as backup in the event of a power failure. Since smoke alarms are placed at ceilings, there’s also a risk of falling. If the battery is not replaced correctly, it might not work properly.

  • Read our disclaimer
  • Read the official manual
  • Hire a qualified electrician if insecure

When is replacement of the battery needed?
The alarm will chirp at random intervals to indicate that the backup battery is running low and needs replacing. However you should replace smoke alarms, when they are ten years old or sooner if they don’t respond properly when tested.

This manual has especially been written for the FireX Smoke Alarm PADC240, but might also be useful for other FireX smoke alarms with a 9V battery back-up, like the I240C and PAD240.

Necessaries
To replace the battery of the FireX Smoke Alarm PADC240, you need:

  • New high quality, long lasting 9 volt battery, NOT a rechargeable one
  • Small screwdriver
  • Step Ladder

Replacing the battery

1. Always turn off the electricity. Locate your house’s main electrical panel. Before replacing the battery, turn off main power by removing the appropriate fuse, or switch the circuit breaker that serves the smoke alarm to the off position.

2. Check that the green light on the unit is off. This indicates that the power has been successfully turned off. Other parts of the room or your house might continue to have lights and power.

3. Find the slot for the insertion of the screwdriver to enable you to remove the alarm from the base.

4. Insert the screwdriver into the slot until you feel a slight movement, indicating that the alarm has been disconnected from the base.

5. Grip the whole top of the smoke detector with your hand and turn it about a half inch counterclockwise. This will release it and you can pull it straight off. Some force might be needed, as it doesn’t necessarily come off easily.

6. Carefully unplug the cable without damaging any wired connections. The beige connector plug with the three wires should pull straight out. It’s probably tight but that’s what you need to do to get the battery compartment open. We did NOT have to push, pull or squeeze plastic “catches” or buttons to release the connector plug, but we had to use muscle power. If you can’t get enough grip on the connector plug with your fingers, you might use waterpump pliers to get it off, but do this at your own risk!

10. Connect a new, 9 volt battery to the connector. Use a high quality, long lasting battery. Using rechargeable or low quality batteries may cause your smoke detectors to fail. The 9 volt battery will have two prongs that need to be pushed into place tightly. The battery will fit only one way. Be sure the battery connector is securely attached to the battery terminals.

How to Replace an Empty Ink Cartridge in the HP Tango X Series Printer – an Illustrated Tutorial in 9 Steps

Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. HP often designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed. HP recommends that you use original HP ink cartridges.

XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print 2 to 3 times as many pages as a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.

You can check the estimated ink levels from the HP Smart app or from the HP printer software (Windows).
