How to Identify and Fix Common Problems ?

Sometimes a `Toner Low` message displays on your computer, and the printer does not print. The message is intended as a warning only so you can have a replacement cartridge available and avoid possible printing delays. You do not need to replace the cartridge until print quality becomes unacceptable.
The replacement toner is already used in another printer
A used toner cartridge will have the reset lever. But because it has been used in another printer already, its reset lever will not be in the right position to activate the printer to reset the toner level. Please use a new, unused replacement toner cartridge.
Pop Out, Push In, Unplug. A simple trick on many Brother printers showing a “low toner” warning is to simply pop the cartridge out of the printer, wait a moment, and push it back in. This resets the printer memory and tells the machine to “look again” at toner levels.
4. Can you use generic ink in HP printers? Yes, you can use generic ink in HP printers. Try to disable the HP Cartridge protection as this will help with preventing the printers from being blocked with updates.
The most obvious sign of low toner cartridge is poor print quality. Streaking, lines or missed prints are all possible signs that cartridge replacement is imminent. If you have tried rocking the toner cartridge and are still getting poor prints, it is likely time to replace your cartridge.
The printer might be low or out of toner, it might have a connection issue, or there might be a paper jam. Clear any problems you find.
To fix toner streaks, first, print several blank pages to see if it fixes the print quality. Next, try cleaning the internal components of the printer such as the laser scanner/mirrors. If this doesn`t work, re-install the toner cartridge.
This error occurs due to the chip on your cartridge still reporting a low or empty ink level from its previous use. The chip itself cannot be reset, so when the cartridge is refilled and then installed into a new machine it will still register as empty.
Saving money upfront to purchase compatible toners can affect the quality, print volume per cartridge, and fail rate if you don`t select your vendor carefully.
Printers rely on ink or toner to produce images on paper or other media. The biggest difference between ink and toner is probably the fact that each of these works with a different type of printer. Inkjet printers rely on ink while laser printers rely on toner, but the differences don`t stop there.
As a general rule, when a printer runs out of ink or toner, it stops printing legibly. Depending on the printer model, the unit may look to replace one colour with another. For example, if you run out of black ink, your printer could replace it with blue, in order to still print the document you need.
You can continue to print with one or more empty cartridges, but HP recommends replacing them as soon as possible to avoid printhead damage.
If your new compatible toner cartridge came without a chip, you will have to re-use the chip from the original HP toner that came with your printer in order to use the compatible toner. The cartridge will work fine EXCEPT the printer will not read the toner levels.
The toner collection unit is designed for a single use. Do not attempt to empty the toner collection unit and reuse it. Doing so could lead to toner being spilled inside the product, which could result in reduced print quality. After use, return the toner collection unit to HP`s Planet Partners program for recycling.
Yes, it is possible on some laser printers to continue to print after the printer indicates that the toner has run out. But most printer manufacturers will not guarantee the print quality if printing continues after the indicator light indicates that toner has run out.
Toner Sensor
These sensors are covered with toner when the cartridge is full, then become exposed over time as you print pages and the toner level declines. When the cartridge reaches a level set by the manufacturer, your low-toner indicator will light.
How long does HP toner last? HP toner cartridges can last up to two years in their sealed packaging. Even after two years you may still get some use out of the cartridge, so it may be worth trying even after the fact. Your printer will display a “low cartridge” message when a specific cartridge needs to be replaced.
More affordable for high-volume print users
While ink is still relatively expensive to refill or replace, toner powder is much more affordable over time.
Locate the waste toner container sensor near the bottom of the Waste Toner Container. Clean the transparent plastic square. Clean the black sensors inside the printer, where the waste toner container sensor is located during normal operation. Power on the printer without the Waste Toner Container installed.
Streaks, smears and stripes on your printout are all signs of a bad cartridge, as is a lack of a particular color or a color appearing very faint. Sometimes the printer refuses to print if a cartridge is faulty.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
The quick answer is: Yes, you can (if you own a printer model that allows it) — but you shouldn`t keep printing with an empty cartridge for too long. Why? Because running on an empty cartridge for too long can cause your printhead to overheat resulting in irreversible printer damage.
Benefits of using toner and laser printers
Furthermore, toner does not dry up in the same way that printer inks do if you don`t print so often, saving time and money.
