41C wand--how fussy should it be?

[quantalume]

I purchased an 82153A wand recently, my first 41C wand, but I've used similar HP reflective optical wands in the past, with and without the sapphire tip. This particular wand won't read any of the barcodes printed from the wand manual available in the museum document set, even codes for single keystrokes. The manual scan is fairly high resolution, and the printed barcodes look pretty decent to my eyes. The wand will, however, read barcodes printed from the PPC DVD. Is this to be expected, or do I have a marginal wand? Also, is there a high-resolution PDF somewhere of the barcode sheets that came with the wand? Thanks.
