If people are picking through your trash to reconstruct images from selphy cartridges and that matters, you probably have bigger operational security issues.
Because that takes a rather determined adversary with non-trivial resources, you probably should avoid doing the things that attract such an adversary.
Thank you for your reply. I wasn't looking for an op sec answer but more of a technical concern around design of the product - i.e why didn't they think of it, or if they did what made them not solve the problem with other tech solutions (dummy prints, zero out, patterns, or even a thermal or physical recycle program). At least communicate this is possible like they addressed the digital safety side of it.
I don't believe it would take too much lift to automate this with a scanner+some software.
This occurs on almost every dye sublimation printer that uses those disposable cartridges. I recall seeing this on a Sony printer from the mid 90s. It's not specific to canon.
Thank you. I wonder if they considered a dummy cycle on a relevant media type after the print to zero out what's left over. Specially if some other patterns could be introduced to randomize what's left.
