You can leave the Printer ON all the time and it is safe. You can setup the Energy Saving Mode to put the Printer in Sleep Mode when not in use. 1.
For healthier print heads and more efficient ink consumption, however, it`s better to leave your printer on. Constantly switching your printer off and on will decrease your printer`s lifespan, so try to keep the off/on to a minimum.
As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.
Ink cartridges can usually last two or three years if properly packaged and stored. But in a standard case, they will eventually dry out and become useless after this period. However, many major ink cartridge makers don`t put expiration dates on their cartridges.
The simple answer is yes. After all, printer ink is a liquid and liquids, especially small quantities stored inside an ink cartridge will eventually dry out.
Over time dirt and dust accumulate inside the printer, which affects it`s functionality. Cleaning a printer regularly can prevent a low print quality or damage to the device.
To keep cartridges from drying out, always turn the printer off using the Power button, and wait until the Power light goes out before you pull the plug or turn off a power strip. This allows the printer to move the cartridges to a capped position.
Ink cartridges can last about two years if they`re properly packed and stored. After two years, you may still be able to use them. But, they can begin drying out and cause some potential issues if you use them on printers, such as getting a dried printhead. An opened ink cartridge can only live for about six months.
The average lifespan of a printer is around 3-5 years. With proper upkeep and maintenance, some printers can last longer, but eventually your machine will need an upgrade.
Generally, the average lifespan of an inkjet printer is around 3-5 years under normal usage. If you use the printer more frequently than average or if you`re using it for a business, you might find the life of your printer is shorter.
Here are our recommendations: Generally, the average lifespan of an inkjet printer is around 3-5 years under normal usage. If you use the printer more frequently than average or if you`re using it for a business, you might find the life of your printer is shorter.
Begin by removing the ink cartridge. Next, carefully wipe off any excess ink on the nozzles of your printer. Then, take your print head and carefully use a small swab with rubbing alcohol to rid it of any excess ink or dust.

HP deskjet 460 Waste ink tank full
ANSWER : I worked fixing printers for 5 years for Verizon and some of the older printers were notorious for the waste receptacle filling and overflowing with ink. My solution was good old warm water. Remove the waste container and scoop out as much as you can with a small screwdriver, wiping the discard on a paper towel, then just run warm water from the faucet into the container till all the residue is removed. This is just water soluble ink folks, if you want to test it, scoop out a glob and dissolve it in warm water, its easy as pie. I never once bought a new ink discard reservoir. I just cleaned out my mobile 460 printer reservoir by the same method. There are no electrical connections its just all plastic.
