Lexmark x4550 wireless scanning
I have a Lemark x4550 wirelessly connected to my WindowsXP desktop computer. It prints fine however I can't get it to scan. Using the control panel on the printer it asks me to select the computer to which I want to scan, I choose the computer and it starts "Downloading Application List". This usually results in an error stating it "Cannot retrieve application list". However sometimes it will give me a list of applications and if I select one of these and try and scan an error screen comes up stating the scan failed. There's also no scan icon in the Lexmark Imaging Studio. Any suggestions. |

No help, I know, but I've never really heard anyone talk about being happy trying to scan wirelessly, except for some specialy usages like barcodes. MM I second MM, I have never heard of scanning wirelessly. There is too much communication between the computer and scanner for wireless to work. The Computer needs to talk with the scanner to set the parameters and the scanner needs to talk with the computer to send the image back. This must be done in real time. I think it has as much to do with the sheer volume of data that must be quickly passed as anything. Even "low rez" scanning, say actual size @ 72ppi generates a lot of bits, and of course if the scanner has to wait for data buffers to clear from scanner to puter and whatnot, it often just craps out, to use technical term. I think barcode scanning can work okay, like grocery store encoding and the like, but there isn't really very much data involved to read UPC stripes. MM |

There's no reason the protocol and network used cannot handle the bi-directional needs of scanning. Wireless "g" and "n" are sufficiently fast enough (if no other problems exist) to manage the data flow. There is nothing inherent to a wireless network that makes it less capable than a wired network given that the wireless network, sof****e, protocol, layers, and hardware are configured correctly. Come to think of it, why would Lexmark release a line of wireless printer/scanners that won't work on wireless networks? The scanner works fine sending data to my laptop, its just my desktop machine I cant get to work. If the scanner works fine with the laptop, it follows that the scanner is fully cappable of interacting with a computer over a wireless netwrok. Therefore, the problem must be with the Desktop or the configuration. I'm curious if you ever connected the laptop to the Lexmark using USB? Some networked printers have to be configured as a local printer to be successfully set up as a networked printer. Connect the Lexmark directly via USB, (re-)install drivers, (re)-install software. Can the Desktop communicate with the Lexmark without errors? If it can, shut everything down, disconnect the Lexmark from USB. Restart the Desktop, and Add the Lexmark as a network printer or change the Port for the printer that was installed - Check your manual for best method if one is suggested. Can the Desktop communicate with the Lexmark without errors now? What happens if you share the Lexmark on the laptop and then connect to the share (Add - Network Printer)? Can the Desktop communicate properly with the Lexmark now? |

It all depends on how smart the scanner is, if the scanner is a true network scanner which can dump encode data and dump files to a NAS automatically, the bandwidth is pretty minimal -- Just look at the size of the resulting file. However, if you're talking a $35 bargain basement scanner, then you're absolutely correct about the bulk of data. |
