Image MF4350d Scanner slow and erratic

[vis]

My mf4350d has suddenly started scanning slowly and the scanner starts and stops when scanning . This occurs with the document feeder or  or when scanning from the platen glass. The  scanning using the mf tool box 4.9 or using program called paper port. Both programs have worked successfully in the past. In addition I have a epson scanner/printer which does not have any problem scanning at a acceptable speed.

Any Ideas whether this is software or hardware?

Hi Vis.

I know that slow scan speeds can be frustrating.  This issue could be caused by a few things, such as TWAIN conflicts, USB hubs or switches, or faulty USB cables.  The items I recommend checking, first, would be the length of the USB cable.  We recommend that the length be 10' or less.  If you're using a USB cable for the Epson, try connecting the cable between the MF4350d and the computer, or if you have another cable handy, swap it with the current cable.  If you have the units connected over a hub or switch, remove the MF4350d from the device and connect it directly.  Also, try connecting to a different USB port on the computer.

Should the above troubleshooting steps not resolve the issue, we recommend that you Contact us for further assistance.

I am also having a problem with my MF4350d. I have 3 of them, 2 work just fine, but a few months ago one of them starting scanning documents much slower. It occurs when copying or scanning. I have a short USB cable. It sounds like some sort of setting, but I could not find how to correct it.

I Have the same problem when connected through LAN... 1 of 3 devices is working slow. Tried on USB (works fine). What could be the problem?
