Mitsubishi Electronics DV1248ST user manual TPO lamp goes out when I lift the TPO unit

2 The Auto Crop function sometimes fails.

Diamond View performs the Auto Crop function by first estimating the outline of the image. If the outline of the image is unclear or can not be easily recognised, the driver will not be able to decide the correct shape to crop. This is usually caused by an irregularly shaped image, image data noise or a dirty glass plate.

If this happens, clean the scanner glass plate with a lint-free cloth and press the TPO unit gently while scanning.

3 The TPO lamp goes out when I lift the TPO unit.

Check to see if the TPO unit cable is connected firmly to the scanner.

4Calibration fail occurs when I scan transparent originals. Check to see if:

The slide/film frame is positioned correctly.

The calibration area of the transparency scanning frame is at the front of the scanner.

The TPO unit is working properly.

The TPO unit cable is firmly connected to the scanner.

5FineReader doesn’t work.

First of all, please make sure you have chosen the right data source for FineReader Sprint. If not, please choose the right scanner in FineReader.

Secondly, set the scanning image type to Line Art. For better recognition performance, set the driver threshold to an initial value to 128. This value may need to be changed depending on the content of the image that is to be scanned.

6 The driver sometimes show the message “SCSI card not found”, and a few minutes later, it works properly.

To prevent damaging the scanner due to an unstable mains power supply or a short-circuit condition on the SCSI bus, the fuse on the SCSI card could be open for a while. During this period, the SCSI card does not function but after a few minutes, the fuse temperature cools down and the fuse recovers. You can solve this question by turning the scanner power off and turn it back on after a few minutes.
