I think I'm getting somewhere, however I am afraid I have not killed off that calibration completely yet.</div><div>Basically, the scanner is still going through some initial short test sweeps to set the light levels. This might not be such a problem, however the scanner now has its light disabled and will eventually be covered and sealed in darkness with the only open area being a 5" square in the middle of the scanning plate.</div><div><br></div><div>At the moment if I cover the calibration area when scanning, I get the following message..</div><div><br></div><div><div>scanimage > foo.png</div><div>[genesys_gl841] **********************************************</div><div>[genesys_gl841] **********************************************</div><div>[genesys_gl841] **** ****</div><div>[genesys_gl841] **** Extremely low Brightness detected. ****</div><div>[genesys_gl841] **** Check the scanning head is ****</div><div>[genesys_gl841] **** unlocked and moving. ****</div><div>[genesys_gl841] **** ****</div><div>[genesys_gl841] **********************************************</div><div>[genesys_gl841] **********************************************</div><div>scanimage: sane_start: Document feeder jammed</div><div>greenb1:~ greenb1$ </div></div><div><br></div><div>Which stops the scan all together, so that's one bit of calibration I need to override. I can still scan successfully with the cover off (some ambient light hits the scan head initially).</div><div><br></div><div> But also in the debug info, I can still see quite a bit of calibrating and shading going on. I can now see "<span class="Apple-style-span" style="font-size: 12px; ">[genesys] Calibration: Cannot open /Users/greenb1/.sane/canon-lide-60.cal" so perhaps that's a good start? I'm hoping that you might be able to </span>see whether our _GENESYS_FLAG_NO_CALIBRATION edits in the backend were successful?, or did I screw up the compiling part?</div><div><br></div><div>If the GENESYS_FLAG_NO_CALIBRATION did work, then it looks like I need to dig further to remove these calibration steps. But perhaps it's just not compiled properly or I am still using the old backend somehow.</div><div><br></div><div>I have included the debug info from a normal (open top) scan as well as the error (document jam) scan with the cover over the calibration area.</div><div><br></div><div>Any Ideas?</div><div><br></div><div>also - just so I can get a handle on what the scanner is doing, I assume the slope tables are something about setting the motor speed to match the sampling rate.
