Canon imageFORMULA DR-S150 error E5-02: Memory Fault

The Canon imageFORMULA DR-S150 error E5-02 is a critical code related to the overflow of the scanner's memory cache during the handling of large or high-resolution documents. This error appears when the internal processor cannot manage the data load sent to the PC, causing a capture system lock. Often, the problem is linked to transfer speed or outdated firmware.

  • 2Outdated firmware failing to manage memory.
  • 3USB connection cable with interference or reduced speed.
  • 4Logic error on the scanner's mainboard.

Solutions

Quick Diagnosis

If the E5-02 error appears when attempting to scan a large batch of documents in high-resolution color, the scanner's internal memory is exceeding its processing capacity.

Step-by-step Solution

  1. Close the scanning software and restart the computer.
  2. Turn off the scanner and let the electronics rest for at least 5 minutes.
  3. Try scanning with a lower resolution (e.g., reduce from 600dpi to 300dpi).
  4. If the issue persists, update the scanner firmware from the support website.

Prevention and Maintenance

Avoid simultaneous high-resolution scanning if the device has a heavy job queue. Keeping the firmware updated improves internal memory management.

When to call a technician

If the error persists even after reducing resolution and updating firmware, the internal memory chip might be damaged and requires a mainboard replacement.
