Toner is the powder ink that latches on to the paper to create text and images. It is stored in the toner cartridge. An image drum is the unit that copies the text and images from the computer and then transfers them to the paper, along with the toner.
Most of the highly viscous printing inks, such as offset printing inks, are thixotropic; therefore, the viscosity of a printed ink is higher than that of the printing ink on the rollers in the printing unit. Hence, the thixotropic phenomenon dries the highly viscous printing inks.
In a nutshell, ink cartridges contain liquid and are used by inkjet printers and toner cartridges contain powder and are used by laser printers. The ink inside an ink cartridge can be either dye-based or pigment-based, depending on which cartridge you have.
The first, direct-imaging, is (usually) a waterless printing process based on imaging the printing plates while they are on press. Plates are burned by laser within the press itself. The job is printed, and the plates are then rolled up into a waste canister so new plates can be imaged—all while on press.
The toner cartridge contains several components including the color pigment used to create letters and images. The imaging drum is the unit that transfers the toner to paper by following the principles of electrophotography. Not all laser printer models require both toner cartridge and imaging drums.
The rheological properties of an ink may depend on different parameters such as deformation γ, processing time t (thixotropic behavior), processing shear rate , temperature T, etc. Inks may also have a yield stress τ0, the minimum shear stress τ above which the ink can flow.
Paints and inks are non-Newtonian fluids, meaning their viscosity is dependent on shear rate.
In ink terminology, viscosity refers to the extent to which ink will resist flowing. The viscosity of an ink will depend on the printing process it is designed for, and the nature of the substrate to which it will adhere. An ink`s viscosity is a component of its body.
A fluid that becomes progressively less viscous when shaken or agitated is called thixotropic. The opposite (and less common) behavior is a fluid that becomes more viscous under constant agitation; this is known as a rheopectic fluid.
While ink is still relatively expensive to refill or replace, toner powder is much more affordable over time. This also makes it more efficient and less wasteful because inkjet cartridges often force users to refill or replace them before they`ve been completely depleted.
Here`s a quick and simple answer: Ink cartridges are expensive so companies can make a profit. Most printers are sold at a loss. A manufacturer makes money NOT by selling consumers an inkjet or laser printer, but by selling the supplies needed to print. The manufacturer controls the technology and the prices.
The toner cartridge is the container that holds the toner powder. The drum unit is an electrically charged cylinder that fuses that toner powder onto paper to create text and images. Both of these components are essential for producing a print.

Inkjet printers sprays ink droplets while laser printers melt toner powder onto paper. With this difference in application between the two inkjet and laser printer types, it`s a common belief that smudging is more common with inkjet printers than laser.
An image drum is a vital part of a laser printer that is responsible for transferring the toner and image or text to paper. It has several different names, it`s also called the imaging unit, drum unit or photoreceptor drum.

Brother toner cartridge low toner override
ANSWER : Thank you. You are a genius. Of course this is not a substitute for cartridge replacement but it is great for extending the life of the color cartridges and allowing you to continue to print until you can get new cartridges.

Expired Toner and Suggestions for Source of Toner
ANSWER : Hi Frank, I had a very similar question two weeks ago, but my “old beloved workhorse” is an HP Laserjet 4L. From the good old days! I too had made bad investments in “new but old truly HP” toner cartridges, hoping to coax more life from my printer. I ended up choosing to try a remanufactured cartridge from www.4inkjets.com. It was a gamble, but the website said they had a 100% satisfaction guarantee. And I can tell you they have lighting fast service. I’ve now printed 50 pages without a flaw. JOY! While the cartridges and technology are different, I suggest you try the same place. And good luck!

run with empty ink cartridge
ANSWER : The only way is to buy a chip resetter and reset the chip on the cartridge. You can find them online for about $5. You just hold it against the cartridge until the light turns green. You do run the risk of damaging the printhead due to overheating because of no ink in it.
