I am getting a regular pattern in my prints, most easily seen in solid
areas. All areas have a regular array of light lines on 4 mm spacing. What
is the cause?

Sounds like a clogged print nozzle.
Have you run the head cleaning routine?

James - that is a condition called "banding." It can be caused by clogged
jets. run a nozzle pattern check to see if they all print ok. If not, do a
cleaning routine and then check the nozzle test again. If you still have a
problem redo the light cleaning and nozzle check. If still not ok do one
heavy cleaning followed by a nozzle check. If you still have a faulty
nozzle check no use to do more cleanings per the canon software. Go to the
nifty-stuff forum, sign in, click on the FAQ link, and read the first thread
about what to do when your printer isn't printing correctly.

Banding can also be caused by a poorly feeding cartridge. Although it is
fairly rare, an OEM Canon cart can be at fault as well as an aftermarket
cart or refilled cart. I don't know how old the printer is, but the BCJ
line of printers is an older generation of the Canon line, so I would
imagine that your are far out of warranty. If you can't clear what appears
to be a clog, you may have a printhead that is starting to malfunction.
Canon printheads use a thermal system to propel the ink onto the paper and
the jets can eventually burn out.

Thanks for the suggestions.

I have tried multiple cleanings, and doesn't seem to help. What is confusing
to me is that all colors seem to show the same effect, even on the nozzle
alignment patterns. It doesn't seem to be consistent with one clogged nozzle
or defective (Canon) cart. Perhaps it is the printhead.

James - generally, a few light cleanings and one heavy cleaning are all you
should try. If they don't work you either have a bad clog or some defect in
the printer - print head, poor electrical contact with the head, defective
board, defective ribbon cable, etc. Unfortunately, none of the printer
manufacturers document cleaning methods beyond the cleaning utility in the
printer software. There are two good sources for printhead cleaning beyond
that which the manufacturers describe. Arthur Entlich, a participant on
this newsgroup, sends his Epson printhead cleaning manual by email on
request, and the Nifty-stuff forum has the best info on Canon print head
cleaning.
