My notes on this are scattered -- I should have organized these back
when the details were fresh in my memory...; I just found another
section of a text file where I have other links and the information
about the possible kinds of reset.
One of the menus had a game, I really think it was pong, but I need to
find the power brick and connect the printer^Wscanner again to check in
which menu it is.
And I just saw a note saying yet another menu is available if you press
back four times (I'm guessing this is in the "home" screen of the
regular interface?). (Which I now see is actually also described in the
two-page article I linked yesterday (page 2, [1]))

At another website, a page [2] mentions a procedure to reset during
power on, I wish I had seen this before sending my previous
reply. Although it requires the "keypad", which I'm not sure 6600 has,
from the photos I've found so far?

(Also, make sure the messages you get after resetting are errors, I
remember seeing, when I was doing the reset-clean reset-instal-remove
try-anything-I-can-come-up-with cycles, messages that could actually be
closed to get back to the home screen, which can be easier to miss when
you've been getting an endless stream of unskippable errors.)
There might have been something about 'clearing' the printhead state by
cutting the power to the printer (so not powering off using the button,
but by disconnecting the power brick from the printer) with the top of
the printer open (and the cart/head in the middle), but I haven't found
yet where did I get this information from (if I'm even recalling it
correctly...). Another page [3] says that a "nozzle test" supposedly
fixes the error.

Nozzle test is supposed to be at least in the menu you get with 4x back,
see the list of entries in page 2 of the two-part article [2].
A note mentions replacing the CR2032 - also mentioned in [3] - 6500A has
one, but I'm not sure it's easily accessible in this model, I was able
to remove and replace it because I was *trying* to access the spittoon
(I didn't get that far, though). As I was doing that, the battery slot
was more easily accessible than with all the covers in place...
