Weak current College】 【scanner quickly troubleshoot troubleshooting.

Determine the scanner fault can be either observation, observation of the produce of the problem, identify the problem component, for example, the scanner does not respond, you can consider that the power cord is plugged in, or test method, test to determine problem areas, for example, scan a picture, find the scanned image is not clear enough; there is the filter method, when when using observation may cause failure found several parts, you can use the screening method to identify the fault location. Sometimes the use of methods that you can determine the source of the failure, and then find a solution.

Can't find your scanner

I believe this is the most common fault. The first observation of the law see the scanner's power and line interface is already connected, and then confirm that the power to turn on the scanner, and then start the computer. If not, you can press the Windows "Device Manager" and "Refresh" button to view the scanner has a self-test, the Green led is steady off. If the answer is Yes, you can exclude the scanner itself the possibility of failure. If the scanner led blinks indicating scanner status is not working properly. Now you can reinstall the latest scanner driver. At the same time, you should also check the "Device Manager" in the scanner is not conflicting with another device (IRQ or I/O addresses) that conflict will be changed. Remember that this type of fault is nothing more than line issues, drivers and port conflict.

The scanner is not ready

Open the scanner power source, if found Ready (ready), no lights, check scanner internal lamp. If you find the internal lamp is lit, and the room temperature, the solution is to let the scanner power on the scanner in half an hour, minute and then open it, the problem can be solved. If at this point the scanner still does not work, turn off the scanner, disconnect the scanner and computer connection between, the value will be set to SCSIID 7, after about a minute and then turn the scanner on. In winter the temperature is low, it is best to use a few minutes before preheating so you can avoid the post after the Ready light is not lit.

Scanned images color blur

First of all by observing the law see scanner on flat glass is dirty, and if so, set the glass with a clean cloth or paper wipe clean, careful not to use alcohol to clean the liquid like that would make the scanned image rendering Rainbow colors. If not glass, please check the resolution of the scanner using, such as the scanner sweep 1200dpi 300dpi more images will be blurred. Because 300dpi scanner sweep 1200dpi is equivalent to the point-and-drop to four times the size. In addition, please check the monitor settings to chromatic 16bit or above. If you are scanning a number of publications which have a certain ambiguity of Anilox is understandable, processing methods you can use the scanner itself with software, you can also use Photoshop and other image software.

Output image color is gorgeous

This is a software failure, you can adjust the monitor's brightness, contrast, and Gamma values. Gamma values are people from dark to bright tone curve of a feeling. The higher the Gamma value, feeling the color levels the more abundant. We can adjust the Gamma value. Of course, in order to get better results, you can in Photoshop and other software to adjust the Gamma value, but this belongs to the "ex-post adjustments", we can sweep the good photos of specific conditions for the adjustment of Gamma value. The scanner comes with the software, if it is a general-purpose, Gamma value is typically set to 1.4; if it is used for printing, set to 1.8; photos on a Web page is set to 2.2. There is a scanner should be performed before using color correction, otherwise you will most likely make the scanned image distortion; in addition to the scanner driver dialog box of the brightness/contrast options for specific regulation.

The problem usually come from the scanner's scan results, which often is also one of the software failure, a different scanner on these software failures have different solutions that can be corrected using the software. But a hardware failure, mainly interface, line problems, as long as everyone connected lines, set the port, use the latest driver, these issues should be easy to resolve.
