How to Spot Pressure Roller Problems During Normal Printing > 자유게시판

During routine print jobs, it’s important to pay attention to early indicators that may indicate problems with the pressure roller. The pressure roller works in tandem with the fuser to deliver consistent thermal force to bond toner to paper. When it begins to wear out or becomes damaged, print quality degrades and the printer may experience jams or unreliable performance.

One of the first signs is streaking or fading in printed output. If your prints show inconsistent density, especially in repeating flaws across multiple pages, the pressure roller may not be applying balanced force. This often happens when the roller’s surface has developed a smooth, shiny finish.

Another common issue is paper jams that occur as paper exits the heating zone. If paper is getting creased or skewed as it exits the fuser area, the pressure roller might be losing traction. This can happen due to foreign particles, degraded internal components, or deterioration in the roller’s rubber coating.

You may also hear unusual noises during printing, such as irregular buzzing. These sounds often point to assembly failure inside the roller assembly. Inspect the roller for physical defects like cuts, dents, or foreign material lodged in its surface.

To help prevent these issues, clean the pressure roller periodically using a microfiber wipe slightly dampened with isopropyl alcohol. Avoid using scrubbing pads or heavy pressure. Also, make sure you’re using paper grades and thicknesses that are within the printer’s rated range. Using too much paper or using damp paper can increase friction.

If cleaning and proper paper use don’t resolve the problem, and غلطک پرس پرینتر print quality remains poor, it’s likely time to install a new roller. Most manufacturers recommend replacing it after a certain number of printed pages, so check your printer’s service manual for recommended service cycles. Ignoring pressure roller issues can lead to damage to other components like the toner transfer system, resulting in more expensive repairs down the line.
