Feeding card stock from the rear tray

[telv]

I mentioned a "slight" ridge. It doesn't originate in-house but is supplied like that (in A4 size) by mainstream paper manufacturers like Mondi. Although the ridge might be barely detectable, it can be enough to make a difference as to whether to not anything other than a fairly new printer can be relied upon to always take up the card. That is how it appears from experiments on four different Canon printers.
