Digital BW, The Print

Hi All;

After all my grousing about this dither-banding problem, I thought I 
should post the solution I arrived at, with some greatly appreciated 
help from Michael Askew. I'm sure this has been posted before, but 
it bears repeating-I can't be the only one that missed it the first 
three times (can I?).

The head alignment (Uni-directional and Bi-directional) did not 
help. Mind you, I got better resolution, and got rid of most of the 
color fringing, but the banding was still there. On Michael's 
advice, I turned off first the "finest detail" option, and then the 
Bi-directional. Turning off "finest detail" made a huge difference-
80% of the banding went away. Turning off Bi-directional (aka high-
speed)got rid of the rest of it, and cleaned up the fine detail some 
more. Never did think much of that HI-speed option, every printer 
I've ever owned has done better without it. Now if I can just 
translate this to QTR-ese, I'll be a happy camper, and I can do 
something else with the 7500-has anyone perfected that coating-fluid 
in-the-printer process yet?

The "finest details" option has to be used only if you print line 
graphics as from CAD. In normal mode it only increased the amount of 
data drasticaly and slow the printing speed down.

You are right, but anyway you may try the "paper feed compensation" 
feature from service menu. This feature is able to compensate most of 
the horizontal bandings. Uni or Bi directional mode.

I apologize to write something most of you know, I believe.

There are many features to tune the printing of Epson LF printers - 
hidden in service menu (accesible by hitting of right arrow in Ready 
mode) or accesible from Epson service utility program.

Try to check it, maybe you'll find the solution of yours problems 
offered directly from Epson.

My 2 cents.
