Troubleshooting

Find the problem you are experiencing
Scanner will not turn on; LCD and power indicator are dark2 checks
Power connection
Check that the outlet has power, the adapter is properly connected and the power switch is On.
Sticky switch
Turn the on/off switch on and off a few times.
CZUR software cannot be installed3 checks
Compatible software and serial number
Use a software release compatible with Windows XP, 7, 8, 10 or 11, or the supported macOS version. Check the serial number under the base; it contains no digit 1.
Security software interference
The guide offers lowering antivirus/firewall security or temporarily disengaging it during installation; reengage it after installation.
Incomplete download
Download the official software again and ensure it completes before installing.
First software use has no preview and cannot scan4 checks
USB connections
Make all USB connections firm, particularly between scanner and computer.
Device recognition
  1. In Device Manager check whether the scanner is recognized.
  2. If a yellow exclamation mark and Unknown Device appear, right-click to update the driver, or disable then re-enable the device and retry the software.
Other imaging drivers
In Device Manager disable other scanner or camera drivers.
Computer
Restart the computer or try another computer.
Scanned image is distorted or its font is twisted3 checks
Misaligned pad
Position the black document pad correctly under the scanner head; scans must fit inside its boundaries.
Oversized material
Make sure the object to be scanned fits within the matte black pad.
Interfering objects
Remove unrelated hands, the hand-button cord, phone, pen or other objects from the preview. Only the document should be in the scanning preview so the algorithms work properly.

Guides

3 product appearance

Instructions from the manual
Recognize the controls, ports and indicators11 steps
  1. The LED brightness control selects high or low brightness; Scan starts the next scan.
  2. The power switch turns device power on or off.
  3. The LCD shows whether images are uploading to the connected computer.
  4. Blinking green video-record lights mean recording is in progress; green off means video recording has stopped.
  5. The power indicator is white.
  6. A separate scan indicator is labelled in the guide; the hand-button light means scanning is in progress.
  7. Connect the computer cable to its USB connection and the hand button or foot pedal to the accessory USB port.
  8. The new and old pedal designs have the same function; the supplied design may differ.
  9. Press the hand button to start the next scan.
  10. The side-light port and touch button belong to the side-light unit.
  11. HDMI and zoom controls in the shared family drawing are optional, for HDMI-equipped models only; this ET18 Pro reference does not assert those controls.

1 scanning preparation

Instructions from the manual
Prepare the scanner and black document pad7 steps
  1. Place the scanner on a table, desk or counter large enough for the pages to be scanned or displayed.
  2. Plug either the hand button or foot pedal into the USB accessory port at the back of the base.
  3. Spread the black document pad under the scanner head and align its notch with the device.
  4. Check the head LCD: the black pad must cover the whole screen with no desk surface or stray edges in the scan.
  5. Correct full-pad coverage is essential to image-processing calculations.
  6. For books or multiple documents, use Computer Mode (USB-PC) and the foot pedal for efficient scanning; computer editing provides additional image adjustments.
  7. Avoid nearby windows and strong ambient light: excessive brightness interferes with the laser lines and scan results.
Align the black document-pad notch with the scanner base, then check the LCD to ensure the pad fills the preview.
Align the black document-pad notch with the scanner base, then check the LCD to ensure the pad fills the preview.

  3. Choose Flat Single Page for single sheets or Facing Pages for bound pages, according to the material.
  4. The illustrations show automatic edge recognition, cropping and tilt correction for single sheets, and curvature recognition, flattening and finger removal with finger cots for books.
  5. For magazines, coated paper, ID documents, glossy paper or glossy books, switch the side lights on and the top/main light off to reduce reflections; the manual limits this to variants supplied with side fill lighting.
  6. Use the device fill light to avoid a shadow from the crossbar casing.
