Hi Music Image
In case you don't have a downloaded version of the service manual, you find it here, with 2 supplements. Instead of clicking download, you can also just click the pdf files and save a copy.:

A parts catalog is found here:

The benefit of the pigment ink for text printing on plain paper documents is a clearer and sharper print as the ink doesn't spread as much on the paper as the dye inks do. It is also more waterproof and resistant to smearing when using a highlighter.
I didn't find any info about which settings and modes use only pigment ink in the service manual.
I don't think the printer has a built in self destruct counter/timer. I think the values on page 1-2 in the service manual are expected or average values.
It has been much debated if leaving the printer on saves ink, by eliminating power up cleaning of the printhead. I think the general opinion is that it saves ink, but that maybe only applies to the later chipped printer models? Personally I don't know.
The appendix has a table of how much ink is used in various types of cleaning. It is found on page 2-2 and 2-3 Maybe you can figure out from this table if leaving the printer always on saves ink. I can't, I think more info is needed.
The manual also has info about service mode operations. From service mode you can print out test and info pages and do an ink absorber reset
plus other things. Be very careful when using service mode operations so not to make unwanted resets or change vital settings. The changes might not be reversible.
And here is an excellent guide to taking the printer apart and changing the waste ink absorbers. This guide is in English even if it is from a German site:

The Pixma 4000 is a very good printer in my opinion, I have one. The build quality is higher than the newest models of canon printers and it is easily refilled and without chips, so I think it deserves some "Tender Loving Care" to keep it alive as long as possible
