Solutions

Quick Diagnosis

Error 42 appears when trying to send a print job or after a failed startup. If the message appears on the screen, try disconnecting the network or USB cable: if the error disappears when disconnected, the issue lies in the communication port or the host computer.

Step-by-step Solution

  1. Turn off the printer using the side switch.
  2. Disconnect the power cable and the data cable (USB or Ethernet).
  3. Wait about 5 minutes for the board's capacitors to discharge.
  4. Connect only power and turn it on. If it starts correctly, connect the data cable.
  5. If the error persists, try updating the firmware from the official Lexmark website.

Prevention and Maintenance

Use high-quality surge protectors. The Lexmark E360d is sensitive to electrical fluctuations; a UPS (Uninterruptible Power Supply) is the best investment to avoid these codes.

When to Call a Technician

If after performing the power cycle and testing with another USB cable, error 42 is still present, the system board is likely damaged.
