The main difference between laser and ink printers are the type of cartridges each printer uses. Laser printers use toner cartridges while ink cartridges are used by inkjet printers. A laser printer uses an electrical charge to instruct where and when the toner should be dispensed onto the paper.
Enterprise-level devices are designed to handle higher print volumes and end-users. In contrast, Pro-level devices are ideal for no more than one to two end-users. For some situations, we do recommend Pro series printers.
What`s the difference between a Laser printer and a LaserJet printer? To put it simply, there really is no difference. A LaserJet printer is a laser printer. It`s just a brand name much like a Kleenex is a tissue or a Q-Tip is a cotton swab.
If you want to print a lot of text, a laser printer might be better. If you want clear, high-quality images, go with an inkjet. Overall, you should consider your space and money constraints, as well as other aspects like noise, whether you`ll want to use photo paper, and how much time it takes to print a job.
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.
Laser printers produce higher overall print quality when taking into account both text and images. However, inkjet printers specialize in color image printing and produce high-quality color photos. When it comes to crisp, clean black and white text and color images, laser printers are unmatched.
Inkjet printers typically run at a lower price point than laser printers, and printer ink is cheaper than toner. However, laser printers and toner have a longer lifespan despite their high cost. Meaning laser toner cartridges have a lower cost per printed page than printer ink.
Color Laser Printer or Black & White Laser Printer

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.

While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output. Given that they`re based on their own unique technology, you`ll find that they also have their own unique advantages and disadvantages.

ANSWER : I would suspect the fixing film has wear. You can prove the theory by doing a half-stop test. This stops the print before it enters the fixing film assembly. Load paper in the drop down MF tray in the front. Send a print job and when the tail end starts to enter, open the cartridge lid on top to stop it. Then remove the toner cartridge and look at the paper. If you see the marks, it is from the toner cartridge. If you don’t, it would be coming from the fixing film since the paper hasn’t entered it.
