When a pressure roller in a printing or industrial machine begins to fail, it often triggers specific fault codes that help technicians identify the issue quickly. These fault codes vary by manufacturer and model, but many exhibit recurring indicators based on the nature of the failure. One frequent code relates to roller overheating issues. If the roller overheats or خرابی غلطک پرس پرینتر fails to reach the correct operating temperature, the system may display a code like heat fail. This can be caused by a degraded heater coil, a faulty thermostat, or reduced thermal conductivity due to coating erosion.

Another common fault code involves sensor malfunction alerts. The machine may show codes such as low pressure detected. These occur when the sensor detects inconsistent pressure during operation. This is often a result of a roller that has become misaligned, has lost its spring tension, or has created localized depressions from continuous heavy-duty cycling.

Roller position or encoder faults are also prevalent. Codes like position tracking failure indicate that the system loses synchronization with roller movement. This usually points to a corroded encoder surface, a slipping drive mechanism, or a roller that is binding during rotation due to seized or degraded bearings or accumulated residue.

Motor-related faults can also be tied to pressure roller issues. If the motor driving the roller faces excessive resistance, the machine may trigger a current surge error. This typically means the roller is binding, the surface is too rough, or there is abnormally high resistance caused by material residue accumulation on the roller surface.

Lastly, communication errors between the control unit and the roller assembly may appear as communication timeout. These can stem from poor terminal connections, deteriorated contacts, or electronic component burnout caused by repeated thermal cycling.

Recognizing these fault codes early can prevent further damage to the system. Regular maintenance, cleaning, and inspection of pressure rollers help prevent common failures. When a fault code appears, always check the roller’s surface integrity and alignment first before replacing expensive components like sensors or motors, as the root cause is often a simple mechanical problem.
