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.

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.
The message `Fuser Error` or `Self-Diagnostic` means either the fuser has reached the maximum temperature allowed or there has been an error in detection of the correct temperature during specific times of the printing process.
The fuser unit or fuser is a critical part of any laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without it, the printer cannot operate.
What causes ghosting? The most likely culprit is either the imaging drum unit or the fuser unit, however humidity and the incorrect paper type can all play a role in ghosting. Ghosting is often caused by a malfunctioning imaging drum unit.
The fuser is a part of laser printers that bonds the toner and paper together using heat and pressure. Fusers need to be replaced every 75,000 – 300,000 pages depending on the printer model.
The fuser unit must be replaced every 100,000 pages, usually along with the transfer belt and feed rollers as part of a maintenance kit. The error code 010-351 indicates that the fuser has reached 100,000 pages and should be replaced immediately. The printer will not operate until the fuser unit is replaced.
Paper could also be jammed inside the fuser where it would not be visible. Remove the fuser to check for jammed paper inside.
The drum rolls the toner onto the paper in the form of your print. The toner is melted & pressed onto the paper by heat from a fuser as it passes through its rollers. Your print comes out of the printer.
The following are the top reasons why paper jams occur:

unsupported paper/media is used. incorrect paper settings in the tray and/or the print driver. paper loaded incorrectly and/or paper edge guides not adjusted properly in the tray.

Generally, you should keep the machine in a dry room. This is because humidity can affect the toner powder and cause it to clump, which has the potential to cause printer ghosting. You should also clean your printer regularly to prevent the chances of the printer not working properly.
The Fuser operates in the temperature range of 175 – 215o C (347-419o F).
Consumables (and mechanical parts) are the things you need to replace during the life of the printer, and can include: Toner cartridges. Ink cartridges. Printer fuser units.
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.
There are replacement rollers and sleeves on the market that you can replace and turn a non-functional fuser into a good working one. Rebuilding fuser assemblies is not a new thing. Copier technicians have been doing it for years since the first office copier was created.
This is accomplished by the fuser lamp. The lamp operates at 120VAC or 250VAC and is typically rated at 500W to 600W. The control signal from the heater control circuit is typically low voltage (< 9VDC).
Thermal printers briefly heat either the surface of special paper or a colored ribbon that marks the paper, but they don`t require warm-up time. None of these technologies need off-duty power to maintain proper function.
Fuser kits replace the heating element in Laser printers that fuses toner onto paper. These elements wear out from normal use, and many printers need a new fuser every 60,000 pages.
A fuser unit is a pair of heated rollers within the printer that fuses the toner onto the paper being printed on. Toner particles are pulled to the paper to create the desired text and images as the paper passes the imaging drum.
The fuser unit is a consumable item that requires periodic replacement. After you have printed approximately 100,000 pages (letter or A4 size paper), the message `Replace Fuser` will appear on the LCD display. NOTE: The actual number of printed pages will vary depending on the print jobs and paper you use.
Low-quality paper leaves an accumulation of tiny paper bits often referred to as “paper dust” inside the machine. This “dust” is one of the top causes of paper jams. More dust means more jams. Besides jams, the dust also contributes to poor-quality prints and causes machine parts to wear at a faster rate.
You`ll know the drum is dirty if you notice that the print quality has become blurry and features blank spots or oddly-colored spots despite having full toner cartridges. Horizontal lines across the printout when the paper passes over a dirty area are another sign that it`s time for some maintenance.
The guides in the paper tray are there to make sure the stack of paper is exactly where the printer was designed to grab from. If the paper is even slightly askew, the rollers will pick it up a little crooked, and — guess what — the crooked sheet will immediately get jammed.
Fuser Wrap Jam: A fuser wrap jam occurs when the fuser detects the leading edge of the paper, but not the trailing edge.
If your printer is spitting out pages full of strange characters, symbols, or strange formatting, your inkjet printer drivers may be outdated, incompatible with your operating system or corrupt. Drivers are important to the proper function of your inkjet printer and it is best to check for updates regularly.
