Troubleshooting Streaks and Smudges from Pressure Rollers > 자유게시판

Inconsistent markings on your prints are frustrating and unprofessional and can ruin the appearance of critical paperwork. One common but often overlooked cause is the fuser roller, which directly enables the bonding of toner to paper. When this component becomes worn, dirty, or misaligned, it can leave behind inconsistent marks that run vertically or horizontally.

The fuser roller is paired with the heating element inside the fuser assembly. As the sheet travels through the system, the roller maintains uniform contact to securely bind the powder to the substrate. If the roller surface is scratched, glazed, or covered in toner residue, it will create intermittent contact with the paper. This leads to incomplete bonding zones, resulting in smudges that rub off easily or streaks that follow the direction of the paper feed.

To troubleshoot the issue, begin by shutting off and removing power from the unit. Wait for the fuser to reach room temperature before accessing the fuser unit. Thoroughly check the pressure roller for visible damage such as cracks, deep grooves, or a shiny, polished appearance. A overheated coating is a definitive indicator that the roller has lost its original texture and lost its grippy texture. Even small amounts of toner residue can trigger inconsistent output, so carefully remove residue from the roller with a non-abrasive fabric moistened with 70% alcohol. Avoid paper towels or rough cloths as they can permanently degrade the roller.

If streaks remain post-wipe, the roller may be worn out. Most pressure rollers have a recommended page yield, often up to 100,000 sheets, depending on the model. If your printer has reached or exceeded its rated output, a new roller is required. Only install a manufacturer approved or reliable aftermarket roller. Budget clones may not meet the temperature and pressure tolerances required and can trigger additional failures.

Also ensure the roller is properly seated and aligned. Sometimes, during routine maintenance, خرابی غلطک پرس پرینتر the fuser assembly can be accidentally displaced. Consult the user guide for steps to reinstall the assembly. Double-check that all connectors and clips are engaged.

Lastly, consider your paper type. Using thick, glossy, or recycled paper that is not rated for your printer can increase mechanical load. Over time, this can accelerate wear. Stick to paper weights and types recommended by the manufacturer.

If you’ve wiped, examined, and swapped the component but streaks persist, the issue may lie elsewhere—such as the fuser lamp or developer unit—but the fuser roller is a top common cause. Taking swift action can save you from costly repairs and ensure consistently professional output.
