You should consider replacing a laser printer pressure roller when you start noticing persistent anomalies in output that don't improve after performing a deep maintenance cycle or replacing the toner cartridge. Common signs include streaks, smudges, or faded areas, especially if they appear in a fixed pattern across all prints. Another indicator is paper jams that occur more frequently, particularly near the heating assembly. If the paper comes out warm but the toner isn't properly fused, the pressure roller may have lost its heat resistance. Over time, the rubber surface of the roller can become brittle, scorched, or polished, which prevents it from exerting consistent force to adhere toner evenly across the media. Most pressure rollers last between 30,000–220,000 copies, غلطک پرس پرینتر depending on usage and printer model, so if your printer has reached that range and you're seeing these problems, replacement is essential for optimal performance.

Always refer to your printer's manual for the manufacturer’s service interval and approved replacement components to ensure proper function and avoid damage to other components.
