I noticed some faint horizontal lines on a 300D print yesterday. I
had seen them on my new CRT monitor previously but I assumed that
it was a CRT oddity (I'm still getting used to moire after using
an LCD for 3-4 years). At the time of the print I thought that I
had a blocked jet, but after some more editing just now I've
realised that since both the CRT and printer display it, the issue
appears to be with the camera.

Is this normal? It shows in areas where there is a fair amount of
one colour, like sky. I'm hoping it's a normal quirk of the sensor
rather than something more serious like a half dead multiplexing
transistor.

Here's a sample 1:1 crop of some sky, it's not the best example but
hopefully the lines are apparent.

Can't tell from your sample. I have a 300D and sometimes get faint
horizontal lines from my printer, but never see them on my monitor.

Zoom in, the lines are very small, like 6 or 7 pixels, but certainly looks
wrong and different to my photos from my 300D.

Those look like jpeg artifacts from really high compression settings. (Yes,
I know it's a tiff, but once you've got jpeg artifacts, saving as tiff won't
get rid of them.)
