Solutions

Diagnóstico rápido

The E-501 is a logic system error. If the control panel responds but printing fails to start or the unit freezes on start-up, the memory likely needs to be cleared via a software reset.

Solución paso a paso

  1. Power cycle: Turn off the printer and wait 60 seconds before powering it back on.
  2. Reset values: Hold down load and menu buttons while powering on to perform a factory reset.
  3. Check cables: Ensure the communication cable (USB/Parallel) is securely connected.
  4. Firmware update: Check if a firmware update is available on the manufacturer's website.

Prevención y mantenimiento

Always use a surge protector. Avoid unplugging data cables while the device is processing, as this corrupts the print cache.

Cuándo llamar a un técnico

If the error reappears immediately after a factory reset, the mainboard may have sustained physical damage.
