If you’ve been using your printer regularly and suddenly notice strange issues with your prints, it might not be the ink or toner—it could be the pressure roller. The fuser unit, which applies heat and خرابی غلطک پرس پرینتر pressure to bond toner to paper, plays a vital role in print quality. When it starts to fail, the effects become noticeable in your output. One of the first signs is irregular banding on your printed pages. These often appear as uneven toner distribution and are caused by degraded silicone layer on the roller. Another common indicator is repeated paper feeding errors. A failing pressure roller may not maintain consistent contact, causing it to get caught in the fuser. You might also notice that printed images look faded or don’t stick properly to the paper. If toner smudges easily, the roller isn’t applying sufficient pressure. In some cases, you may hear unusual noises like grinding, clicking, or squeaking, which suggests internal wear. A burning smell coming from the printer is a critical sign that the roller’s fuser assembly is failing. Lastly, if your printer starts displaying error codes such as "Toner Not Fusing", it’s often a clear indicator that the pressure roller needs attention. Ignoring these signs can lead to costly internal repairs, so if you see any of these symptoms, it’s best to inspect or replace the roller before it causes a unexpected shutdown.
