Troubleshooting

If you have any operational problem, please check the following troubleshooting hints. 6.1 Questions and Answers
Question: Why the scanned image always comes out to be too dark? Answer: 1) Modify the Gamma setting to 1.8 for your monitor and, when printing, set Gamma to 2.2 for your printer. 2) Use the Brightness setting of the TWAIN user interface to get a brighter image. Question: The scanning speed of my scanner is much slower than that of those installed at other computers. Can I speed it up? Answer: Set you PC printer port to the EPP mode from BIOS setting. Question: Why does my scanner scan at a very low speed? Answer: If you have installedWorks for Windows,it will install Window Printing System (WPS) in your WIN.INI file. This will take up the printer port time remarkably. You can remove the WPS from your WIN.INI file, as follows:

Question: The printer does not print the documents. Why? Answer: Pass-through printing may pose a problem for some printers. It is suggested to add a second printer card for printing purpose, or you may call your authorized local dealer for further support. Question: Does it take long for the scanner to initialize? Answer: If your printer port supports SPP mode only, it takes about two minutes for the scanner to initialize. If your printer port supports EPP mode, the initialization speed is much faster, about 20 seconds. Question: Why sometimes pass-through printing does not work at all? Answer: It may be that you fail to power on the scanner. When doing pass-through printing, please be sure to power on the scanner. Else, without power, the scanner can not transfer the printing data/signals to the printer.
Question: Why my GDIprinter does not work with the AV260C Plus? Answer: Disable the Auto Scan function in the application, then your printer will function in normal working condition. Question: Why some parallel port devices and softwares keypro do not work with the AV260C Plus? Answer: The AV260C Plus can do pass-through printing all right , but the pass-through printing may not work if you connect the parallel port with devices other than printer. Therefore, if you would like to connect some parallel port devices other than printer, please do not connect them to the same parallel port that AV260C Plus currently uses. It is suggested to use other parallel ports to connect these devices or keypro. For instance, you can connect the AV260C Plus to LPT1, and connect other parallel port devices to LPT2. Or you can add a data switch to avoid the problem.
