    Re: DPL users/owners of Howtek/Aztek scanners

    This information is most useful. I have the 4500 Service manual which specifically mentions lubricating the lead screws. One question I have is when you mention use teflon silicon lubricant on the rails, which component you are talking about. I did not see that in the service manual. Please help me out.Since these scanners are old and the service is next to impossible, it behooves us to keep them in good shape. Thanks once again

    The bottle of the teflon silicone lubricant is clear so you will notice the teflon accumulated the bottom. Shake it a little before applying. I use a piece of old flannel to clean the rails but any soft fabric should do the job.

    Unfortunately I am missing Section 7 of Howtek 4500 Service Manual. Can somebody upload it please!

    I've a 4500 and use DPL Pro and Silverfast. I've done a lot of testing and have seen no advantage of using the pro software. I only ever use Wide Gamut Negative and Generic Chrome.

    For transparencies though I prefer to use Silverfast. It has a very nice balance of shadows and highlights and seems to get better focus more often.

    However for negatives, DPL is the biz using the Wide Gamut Negative and then inverting by hand in photoshop.

    I also operate a Heidelberg Primescan, Screen Cezanne Elite Pro and two Fuji Lanovias

    Tim,

    Thanks for your comments on DPL Pro versus Silverfast. I have a Howtek 7500 that is working well with a MAC running OS 10.4 and Silverfast 6.6 and have been wondering if there would be any significant advantage switching to PC and DPL Pro. I scan primarily negatives, color and B&W, and am curious as to the advantage you see in DPL over Silverfast for negatives with Wide Gamut Negative and then inverting in Photoshop?

    In my opinion Silverfast 6.6 is a much better choice for Howtek scanners than Aurora. Even if you have a full set of disks for Aurora you still need a dongle to make it work, and in the Macintosh world Aurora works only with the old classic (pre OSX) system.

    The only significant problem I have found with Silverfast and the MAC is that Version 6.6 only works with OS 10.3 and 10.4, and MAC OSX is not very SCSI compliant so the choice of card is very important. I was using the D4000 with OS 10.4 with an Adaptec 2906 SCSI card but this combination would not see the Howtek 7500, and I also had problems with an Adaptec 2930 card. The most reliable SCSI card I have found for MAC OS X with the 7500 is the Acard AEC-6712WM/TUM.
