When a pressure roller in a printing or industrial machine begins to fail, it often triggers specific fault codes that help technicians pinpoint the problem efficiently. These fault codes differ across brands and units, but many exhibit recurring indicators based on the nature of the failure. One frequent code relates to thermal regulation failures. If the roller overheats or cannot attain target heat levels, the system may display a code like thermal fault. This can be caused by a degraded heater coil, a faulty thermostat, or غلطک پرس پرینتر hp poor thermal contact due to material wear.

Another common fault code involves pressure detection failures. The machine may show codes such as pressure out of range. These occur when the sensor registers erratic readings during operation. This is often a result of a roller that has become misaligned, has lost its spring tension, or has formed worn patches from continuous heavy-duty cycling.

Roller position or encoder faults are also prevalent. Codes like pos err indicate that the system fails to maintain positional feedback. This usually points to a damaged encoder strip, a improperly seated shaft connection, or a roller that is binding during rotation due to bearing wear or foreign material obstruction.

Motor-related faults can also be tied to pressure roller issues. If the motor driving the roller cannot maintain torque, the machine may trigger a drive failure alert. This typically means the roller is seizing, the surface is too rough, or there is excessive friction 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 loose wiring, corroded connectors, 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 extend component lifespan. When a fault code appears, always check the roller’s physical condition first before replacing expensive components like expensive electronic parts, as the root cause is often a simple mechanical problem.
