How to update firmware on Howtek D4000

Postby mcfactor » Thu May 14, 2015 9:38 pm


I am attempting to resurrect a Howtek D4000 that has been sitting in storage for a very long time. It turns on fine all the diagnostics are fine. I got silverfast to recognize it and open, but when I try to do a prescan I get "cannot set window" or "cannot auto focus" if the auto focus is on (but it focuses fine manually). I saw on a different forum (howtek-d...end-t4156.html) that someone else had the same problem, that was fixed after updating the firmware. I found and downloaded the r535 firmware from Aztek, but I cannot figure out how to install it. I opened the program, a box came up then closed, leaving a .hex file and another program that does not seem to do anything. I am using a windows 7 machine with an Adaptec 2930CU card. I really just need to know how to update the firmware on the D4000.

Any help or ideas would be great.

Dear customer,

Does the lamp in the scanner light up?
The issues you describe could also be caused by an insufficient light source.

I am not sure, but I assume the manufacturer software offers a way to upgrade the firmware.

Kind regards,
Arne Ketelhohn.
