When the machine is then powered on, the fuser and the interior of the machine heats up the toner or dust and a smell occurs until it all dissipates. In extreme cases, the smell can linger for several hours. A burning smell may also be noticed if there was a paper jam in the fuser and it wasn`t removed completely.
The smell is typically from the normal operation of the machine and can be toner, room dust, or ozone. The smell can be more intense if the printer has been off for a length of time and toner or dust builds up on the fuser unit or on the charge corona wire in the drum unit.
Occasionally, we have to deal with overheating. This is when the temperature of the filament stays too hot for too long, resulting in it melting away and distorting your print model.
Warmer temperatures have the opposite effect. The ink becomes thinner, creating unreliable, messy printing. Additionally, the higher temperature ink may cause damage to the cartridge-attached print head, resulting in the need for a new ink cartridge.
Steam coming off your printer is not uncommon, particularly if the media that you are printing on is damp. This may produce a water vapour or steam.
Xerographic copying and printing equipment may generate ozone when high-voltage charging devices produce an electrostatic discharge during a copy run. In standby mode no ozone is produced. The word ozone is derived from the Greek word for smell.
Streaking, smudging, black lines, and double images are all symptoms of a bad fuser. When you notice these printing defects and experience problems, such as paper jams or wrinkles, this is a good sign to replace the fuser kit.
Why is it important to clean a laser printer? Printing is vital to all businesses so ensuring your laser printer is thoroughly cleaned is crucial as it allows your machine to continue working efficiently. Cleaning a laser printer is easy with the correct equipment, however they are prone to dust and debris.
The Fuser is the piece that fixes the toner on the paper. This, like any other consumable part, wears out with the regular use of prints, since it is one of the components that suffers the most due to its mechanical wear and overheating of its components, due to the high temperatures it must withstand.
As with other tools, our laser systems require some maintenance to ensure it works optimally. For instance, failing to maintain the laser solution can cause overheating — which can be catastrophic.
2. Laser printer fusers heat up to a temperature of nearly 400ºF to fuse the toner to paper. The paper must move as fast as possible through the rollers so that it does not have time to burn. Talk about hot off the press!
Extremes of temperature and moisture can damage delicate printer parts, and dust can build up and cause problems with printing quality.
Normally, the fuser unit comprises two rollers, the upper roller is heated and is designed to melt the thin film of toner plastic, enabling the ink to be transferred to the paper as it passes between the rollers.
Fuser Rollers and Roller Sleeves

During the fuser melting process, the paper is pulled through the two rollers inside the fuser unit. The top roller is very hot and melts the toner particles into the paper. The bottom roller is sometimes also heated such as in the case of duplex (double-sided) printing.

While you still should keep your distance from that coughing coworker, you also should avoid sitting near the printer, as its toner could be toxic to your health.
Airborne particles within an office environment are a combination of particles generated from various sources, included are laser printers which emit paper fibres, organic vapours and inorganic gases. Research has shown that laser printers emit nanoparticles of substances, which could increase the effects of exposure.
The smell of ozone in low concentrations is often described as sweet. In higher concentrations, however, it is more pungent. Most people are not affected by ozone emissions from a laser printer. The ozone generated by laser printers has a very short life span and decomposes back to oxygen very rapidly.

Toners are heated up to make them bond to what they are being printed on. This is when they emit their signature smell.

An olfactory hallucination (phantosmia) makes you detect smells that aren`t really there in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils.
Solvents and inks can irritate the skin leading to dermatitis. Some products can cause skin allergy and asthma (eg UV inks, laminating adhesives) Some solvent vapours can make you dizzy, drowsy and affect your central nervous system.
When unpacking a new shirt or hoodie with a direct-to-garment (DTG) print, you might notice a vinegar-like smell or an off-white residue. Don`t worry, that`s not unusual – it`s from a fixation agent applied during the printing process, and it`s not permanent.
The fuser unit is a vital component of laser printers. Most fusers last between 50,000 and 200,000 pages, depending on the design.
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.
Laser printers can print much faster than inkjet printers can. Most are equipped with high-capacity paper trays, so they can print more pages at a given time. They`re also built to handle the printing of thousands of pages per month without succumbing to wear-and-tear.

Fuser burning labels
ANSWER : Make sure the labels are rated for a laser printer as the ones for inkjet printers cannot tolerate the heat produced by a laser printer and will tend to scorch. If the labels aren’t rated for a laser printer then there may be nothing wrong with printer.
