300 dpi should be fine for my needs, I believe the Brother
HL5140 Laser can do better though. The problem was mainly the
resolution setting in xsane which initially defaulted to 80 dpi.
The ideograph in the menu looked to me like the symbols for
setting line width, brush size or something in Gimp and I did
not recognize it as resolution. Once changed to 300 dpi I got
usable copies.
I find the following for the HL5140 printer: Max Resolution (
B&W ) 2400 dpi x 600 dpi
I assume 600 dpi is along the horizontal axis? It is presently
configured to print 300 dpi.
The HP5370C Scanner: Resolution 1200 dots per inch (dpi) optical
resolution
1200 x 2400 dpi hardware resolution
unlimited interpolated resolution (HP Scanjet 5370C scanner only)
I guess that says I should be able to set xsane to scan 600 dpi
and produce copies, however there were other problems. Each time
I changed resolution in xsane I had to unplug the USB scanner
and restart xsane or things would "lock up!" Something bad was
happening because after producing the needed copies Thunderbird
Mail locked up too, something that is not normally a problem. I
eventually bit the bullet and rebooted the computer.
I left one doctor's office with copies of my blood work and
wanted a second copy to give to the hematologist. Usually the
computer/scanner works nicely as a copy machine but I guess
that's the first time I used this computer for that purpose
since installing F-15 64 bit. I was panicking when things didn't
work as expected! Sorry.
Thanks,
Bob.
