How to Replace an Empty Ink Cartridge in the HP Deskjet 2751 All-in-One Printer – an Illustrated Tutorial in 11 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. Unlike other inkjet manufacturers, 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.

You can check the estimated ink levels from the printer control panel, from the HP printer software, and from the HP Smart App.

To check the ink levels from the printer software (Windows):
– Open the HP printer software.
– In the printer software, click Estimated Levels.

To check the ink levels from the printer control panel:
The Ink Level icons on the printer display show an estimate of ink remaining in the cartridges.

To check the ink levels from the HP Smart App:
Open the HP Smart App on your mobile device. The estimated ink levels for your printer appear at the top of the screen, beside the picture of the printer.

XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print almost 2 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.

Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable.

Use the single-cartridge mode to operate the HP All-in-One with only one print cartridge. The single-cartridge mode is initiated when a print cartridge is removed from the print cartridge carriage.

For your US HP DeskJet 2751 All-in-One Printer you need HP 67 Black AND HP 67 Tri-color cartridges OR the XL versions: HP 67XL Black AND HP 67XL Tri-color cartridges.

How to Replace the battery of a Nokia 105 / TA-1037 Cell Phone – Tutorial



Make sure you purchase the right battery for your Smartphone. Batteries are not compatible between different brands, and often not among phones within the same brand. It’s recommended that you use a genuine Nokia 105 battery.

Which battery do I need for my Nokia 105 / TA-1037 Cell Phone?
For your Nokia 105 / TA-1037 Cell Phone you need a a lithium-ion rechargeable battery (sometimes called a Li-ion battery or LIB): Nokia BL-5C Battery, 3.7V 1020mAh, 3.8Wh.

Replace the Battery

1. Turn off the power so that you won’t lose any stored information. If the device is on, press and hold the power/end-call button for a couple of seconds, until the phone shuts down.

2. Remove the back cover. Hold the device in one hand and find the small notch that will help you to release the cover. It’s on the the bottom of the phone. Insert a fingernail into the notch. Lift upwards gently to pop the phone open. Some force is probably needed. Be careful not to damage your fingernails when you remove the back cover. Also, be certain not to bend or twist the back cover excessively. Doing so may damage the cover.

Align the three gold colored contacts with the three prongs on the bottom-right side of the battery slot, as shown in the pictures below. Slide the battery into the battery housing cavity and press down gently to secure it in place. It should fit easily and exactly.

9. Check if your new battery is recognized by the device and if it’s already charged to some extent. Many battery manufacturers ship new batteries with their batteries charged around 60%. In this case, there is no real need to charge the battery before the first use. A good rule of thumb seems to be to never charge your phone up to more than 80 percent of capacity.

How to Insert a SIM Card into a Nokia 105 / TA-1037 Single-SIM Cell Phone – Tutorial



Which SIM Card do I need for my Nokia 105 / TA-1037 Single-SIM Cell Phone?

Note: it appears that there are two versions of the Nokia 105 / TA-1037 available: a single-SIM version and a dual-SIM one. This manual has especially been written for the single-SIM phone. However, the basics are the same, so you can use this tutorial for the dual-SIM version too.

Make sure you use the correct size SIM card. Depending on the model of phone, there are three sizes of SIM card that can potentially be used in a phone: Standard Mini SIM, Micro SIM and Nano SIM. The three SIM card types work in exactly the same way from a technical perspective. They just differ in the amount of plastic housing that surrounds the metallic chip. The Combi SIM is a Micro SIM card within a Standard Mini SIM-sized unit, so if you need the smaller size of card you simply break the additional plastic away from around the Micro SIM card. This type of card allows networks to cater for more phone users with a single card. A Trio SIM is a Standard Mini SIM, a Micro and a Nano in one. Most of the pay-as-you-go SIM cards you buy from convenience stores operate under this format as they’re more useful to more users.

The Nokia 105 – TA-1037 only accepts 1 (sometimes 2) big standard Mini SIM size card. You can also use a Combi SIM or Trio SIM and NOT break away the plastic from around the SIM card. Only remove the Standard SIM from the plastic card.

Sometimes getting a replacement SIM from your mobile network provider could be a hassle. If you already have a smaller SIM or if you find yourself switching phones around a lot, you may need to adapt — with a SIM adapter — any time you need to go bigger. They are used to transform your sim card into a bigger size which is compatible with your phone. These adapters are quite cheap to purchase, however, getting a good quality adapter would mean that it would be able to let you fit your sim tightly. Using one of those thin flimsy plastic SIM adapters (they usually have a hole in the back) or use one that uses tape to hold the SIM in is NOT recommended. Don’t place an empty SIM adapter in your phone, you must use it with the SIM card already inserted. An empty adapter might damage your phone.

Popular SIM card adapters cards include, but are not limited to:

  • Gold Samdi Brand Nano Sim Adapter and Micro Sim Adapter and Nano to Micro Adapter with a Sim Card Folder and a Needle
  • Sadapter Three Adapter Pack – Retail Packaging – Black
  • Noosy Sim Card Adapter Kits with Nano Sim Adapter and Micro Sim Adapter

Insert a SIM Card

1. Turn off the power so that you won’t lose any stored information. If the device is on, press and hold the power/end-call button for a couple of seconds, until the phone shuts down.

How to Insert or Remove a SIM Card and Memory Card into a Motorola Moto G9 Play Smartphone – Tutorial



Which SIM Card do I need for my Motorola Moto G9 Play Smartphone?

Make sure you use the correct size SIM card. Depending on the model of smartphone, there are three sizes of SIM card that can potentially be used in a phone: Standard SIM, Micro SIM and Nano SIM. The three SIM card types work in exactly the same way from a technical perspective. They just differ in the amount of plastic housing that surrounds the metallic chip. If your SIM card is too big for your phone’s SIM card slot, you can cut it with a SIM card cutter.

The Combi SIM is a Micro SIM card within a Standard SIM-sized unit, so if you need the smaller size of card you simply break the additional plastic away from around the Micro SIM card. This type of card allows networks to cater for more phone users with a single card. A Trio SIM is a Standard, a Micro and a Nano in one. Most of the pay-as-you-go SIM cards you buy from convenience stores operate under this format as they’re more useful to more users.

The Motorola Moto G9 Play only accepts Nano-SIM Cards.

You can use two SIM cards with different phone numbers in a Motorola Moto G9 Play. However it’s a hybrid slot, that means the second SIM card slot is also where you place your microSD card. You cannot insert two SIM cards and one microSD card at the same time. You must choose between one SIM card and a microSD card, or two SIM cards. The Motorola Moto G9 Play support DSDS (Dual SIM Dual Standby), which doesn’t allow two calls on two different SIM cards, but allows you to forward calls that come in on SIM card 1 to SIM card 2 when SIM card 1 is occupied and vice versa. This function is called Dual SIM reachability.

Which Memory Card do I need for my Motorola Moto G9 Play Smartphone?

Make sure you purchase the right Memory Card for your Smartphone. Your Motorola Moto G9 Play built-in memory is usually 64 GB. Users who demand more memory from their Phone can install an external microSD (sometimes named microSDHC (High-Capacity) or microSDXC (eXtended-Capacity) memory card with a maximum capacity of 512 GB. Class 2, 4, 6 or 10 cards will all work.
motorola moto g9 play how to insert or remove sim cards and sd memory card 02

A popular memory card for this model is for example: SanDisk 64GB Ultra MicroSDHC UHS-I Memory Card with Adapter.

Portable storage
When you insert an SD card in a smartphone for the first time, you can sometimes choose to either use the card as Portable Storage or Internal Storage. Your Motorola Moto G9 Play uses the card as portable storage for media files like photos, videos, and music. Because it’s portable, you can easily swap the card and its content between devices. After you insert the card, you might want to update settings within media apps (like camera, music, and podcast apps), so they use the card to store content you create or download. You can’t store apps on the SD card because it is portable storage.

Many microSD Cards come with an SD Card adapter for compatibility with SD-enabled devices, such as cameras, camcorders and (notebook) computers. Memory cards usually come pre-formatted and do not need to be formatted out of the box. MicroSDHC/MicroSDXC host devices are required to accept older MicroSD cards. If you insert a card formatted with an unsupported file structure, your Motorola Moto G9 Play will ask you to reformat the memory card. Formatting your memory card on a PC may cause incompatibilities with your device. It’s recommended to format the memory card only on the device.

We recommend storing multimedia files (such as music, videos and pictures) on an external memory card in your device to free up your device’s internal memory for applications. Plus, when you purchase a new Smartphone, you can simply swap your memory card between your old phone and your new device and all your data is back immediately.

Insert a SIM Card and memory card
1. First, remove any protective case or cover, if you use any. Motorola includes a basic clear plastic one with the phone.
