More D4000 banding

Postby hdd » Fri Jul 16, 2004 10:15 pm

I am also having a problem with banding while using the demo version of silverfast on the howtek d4000. banding does not happen when I use trident software. Any ideas why? Thanks.

Howtek D4000 Banding Issue

Postby electricart » Thu Feb 22, 2007 2:14 am

Hi all,

I concur that Silverfast and our Howtek D4000 also has the banding issue. We are using the latest firmware for the scanner (R535) and the latest version of Silverfast - 6.5.0r3d(Howtek) on Mac OS 10.4.8.

We have mainly seen this problem on large negatives and transparencies - most notably on 8x10 negative.

We do not have the banding issue when using the same hardware but alternative software, in our case the original Howtek Scanmaster OS 9 plug-in.

We do not have a full version of the Trident scanning software to test with, however we have tested with an OS 9 version of Silverfast to make sure the issue was not with the SCSI cable, card or the OS X Adaptec 2930 driver, and can confirm that the banding issue exists with Silverfast under OS 9 as well.

This is a major issue, especially when scanning large negatives or transparencies. We have sent multiple emails to support, we are yet to receive a reply, but we hope that the issue can be resolved soon.

Silverfast is amazing software, and has a great deal of well implemented professional features that we cannot do without, so I would highly recommend the software to users seeking an alternative (especially for an older drum scanner like the Howteks) however until Silverfast have resolved this issue regarding banding and the D4000, I would not recommend purchasing the software.

kind regards,

Dear Howtek Drum Scanner Users,
i can confirm that we found & fixed the bug, now that we had access to a Scanner that actually showed the Problem !
A Test Customer also verified on 2 Howtek Drum Scanners that the banding is gone !

The fix will be included in the next regular Web update ( within 10 days ), namely Version 6.50r8 !

If you still use Version 6.4XXX and you do not plan to upgrade anytime soon, please contact me at: ( please allow some days for processing )

and i will send you a patched 6.4XX Plugin as a patch for your installation !

( You should really consider upgrading as 6.5 offers a whole lot of new features, e.g. free Rotation ).
