Epson 1200 - Scan Speeds Benchmark Results

Post by David Chie » Wed, 15 Mar 2000 04:00:00



Benchmarks from the Epson 1200S SCSI scanner.  Would appreciate
if an Epson 1200U USB user posted results as well
for comparison.

Epson 1200S attached to Adaptec 2930U2 SCSI card in
400Mhz AMD K6-2 system with 128MB RAM and 8GB HD.
Twain 4.10E from www.epson.co.uk.

Scanned image was the printed Photodisc test target at
http://160.87.101.59/ printed on 8.5x11" paper with 0.5"
margins all around, image scaled to margins of page,
aspect ratio maintained.

At 1200 & 2400 dpi, HD access occured to swap portions
of RAM to disk, however, the scan rate did not slow
(ie. the timings are mostly unaffected by the HD access).

At 1200 dpi, 1/2 of the image (8.45"x5.5") was used
for the test instead due to the huge size of a full page.
Times were multiplied by 2x to get the final scores.
At 2400 dpi, 1/8th of the image was used.  The top portion
of the page closest to the scan head was choosen to reduce
any head seek times across the empty flatbed to reach
the portion to be scanned.

8.45" was the maximum width allowed by the Twain scanner
software.

Unmask Sharpening on or off did not affect scan times.
