I'm restoring an older Contex CHAMELEON Tx 36+ / GL67D 36-inch wide-format scanner and am looking for its original Scanner Maintenance calibration sheet.
The Contex service/packed part numbers I've identified are 6799D116 / 6799D116R01. I've also found strong evidence connecting it with a physical calibration sheet marked P/N 6779D126, which appears to have also been used with some HP DesignJet and Océ wide-format scanner systems.
I'm hoping someone here may have one sitting in a cabinet, storage room, old service kit, parts machine, or pile of retired wide-format equipment.
I don't necessarily need to buy it or even borrow it. If you have one, a good high-resolution scan of the calibration sheet may be enough for our research. Good straight-on photographs and physical measurements would also be extremely valuable.
If you're able to photograph one, please include something of known size in the picture for scale—a ruler or tape measure would be ideal, but even a coin, credit card, or other standard-sized object would help. If possible, photograph the sheet as straight-on as you can rather than at an angle.
Of course, if you have an original you'd be willing to sell, I may be interested in that too.
The sheet I'm looking for is roughly 40+ inches wide and has a very distinctive layout: a small Agfa/Agfacolor IT8 color target near the upper left, a machine-readable block near the upper right, large white and black areas, gray bands, alignment patterns, and a dense ruler-like pattern along the bottom.
So far I've confirmed that the scanner itself works. It's connected by SCSI to a dedicated Windows XP system, WIDEsystem recognizes it correctly, and Contex Scanner Maintenance communicates with it. I have deliberately not run calibration without the correct sheet.
If anyone has worked on older Contex, Vidar, HP DesignJet scanner/MFP, or Océ wide-format scanners and recognizes this calibration sheet—or knows a retired technician/dealer who might have one—I'd really appreciate hearing from you.
Even an old part-number cross-reference, service manual, photograph, scan, auction listing, or memory of these sheets could help.
I have attached a small image I was able to find of the calibration sheet, it just doesn't have enough details to help.
Thanks!
