The better of the lot among portable scanners can work independently. Others, like the HP Scanjet 1000 Mobile Scanner, need to be connected to a PC to do the job of scanning documents.
You are ready to go once the software has been installed, and Scanjet 1000 is connected to the PC via the USB cable. This cable also acts as the power source for the scanner. We tried initiating a scan using the scanner key, but without success. Finally, we had to fall back on the scanner software to do the job.
Though the default scanning resolution is 200 dpi, you can opt for between 100 and 600 dpi. Similarly, the default file format of PDF can also be changed under the options tab. Though noisy enough to attract the attention of everyone in the vicinity, it has to be agreed that the Scanjet 1000 scans really well. In fact, it can easily scan both sides of the document, just select the software option of saving both sides being scanned in a single file. Once a page is scanned, the software asks if you wish to scan another page. Scanning at 600 dpi takes longer, though the results are impressive.
