If some keys do not work, checking the connection quickly might be enough to solve the problem.
If you have access to another computer, use its printing and connect it to your computer. If the new printing works, you know that your original printing, or its connection, is to blame.
Reconnect your original printing using another USB port on your computer. Restart the computer and try again.
Wireless printings are energy-hungry. Replace the printing batteries before restarting the computer. Make sure the wireless printing is "connected" to your computer via Bluetooth: your computer will ask you to configure this connection at startup.
If key groups do not work, the printing probably has an electronic fault that needs to be repaired by a professional. If no keys work, check the connections on your printing. For the right Printing in Sydney this is the perfect option.
My printing is dirty
Dirty keypads and clogged keys affect your productivity, and pose a health risk because of the harmful bacteria hidden in them.
Flip the printing over and tap it to drop dust and dirt, then use a vacuum cleaner with a small nozzle to suck debris between the keys.
Use a wet wipe to remove grease on the keys.
In case of heavy grime, remove the keys by gently lifting them with a small flathead screwdriver. Take a picture of your printing first to find out where to put them back. Soak a cotton swab with isopropyl alcohol and wipe the residues under the buttons and around them before putting them back in place.
The right tools
Isopropyl alcohol, also called isopropanol or rubbing alcohol, is an ideal cleaning product for electronic devices. It lifts fat and glues with ease and evaporates quickly. You can get them from pharmacies or electronics stores.
