You should consider replacing a laser printer pressure roller when you start noticing recurring print defects that don't improve after cleaning the printer or replacing the toner cartridge. Common signs include uneven toner deposition, ghosting, or washed-out text, especially if they appear in the same location on every page. Another indicator is repeated paper transport failures, particularly near the fuser area. If the paper comes out tempered but ink lifts under touch, the pressure roller may have lost its heat resistance. Over time, the the fuser roller’s elastomer layer can become worn, خرابی غلطک پرس پرینتر cracked, or glazed, which prevents it from maintaining uniform contact to adhere toner evenly across the media. Most pressure rollers last between 40,000 to 250,000 prints, depending on usage and printer model, so if your printer has reached that range and you're seeing these problems, replacement is likely needed. It's also wise to replace the roller when you're installing a new fuser assembly, since they function as a synchronized pair and replacing both at once can save time and labor. Always refer to your printer's manual for the official maintenance guidelines and compatible parts to ensure reliable operation and avoid harming internal mechanisms.
