Hello,
I am on the lookout for an all-in-one inkjet printer that will also
print on dvd/cds
I had been looking at the Canon PIXMA MX925, however while this
printer ticks all boxes the reviews suggest that it constantly goes
into cleaning cycle using/wasting ink.
Every inkjet printer (all makes) does that, the only question is whether this
printer is any worse than the rest; while I don't know the answer to that I
would be surprised if it is any different to any other Canon inkjet.

Epson uses piezo electric heads and the original bubble jet was Canon, the
original inkjet was Siemens (I think) but the name was adopted by HP. Epson
heads clog more than any other manufacturer because of the very high tech heads
they use to produce high quality. The fact is that piezo heads last a long time
but clog easily and are extremely difficult to fix - they need to be used
regularly.
I have never seen a Canon head burn out and I have never seen a Canon printer
where a clogged head could not be unclogged. Most manufacturers use heat to
deliver ink and they can burn out but nothing like as common as peple think,
the usual problem is clogging which requires ink to be forced through the head
to clear it. Several manufacturers have large capacity tanks and tfor those
that don't external tanks are usually available.
Epson quality is high, the downside is the reliability of the piezo technology.
In maybe 2500 (at least) printers I have worked on I have seen maybe 5 that had
burned out heads - very rare indeed - clogging is the issue.

Thanks for the history compilation, interesting indeed.

One Big advantage is that the Epson does not have to use Water Based
Inks.

One issue I had with Epson is the almost comical efforts at recognizing
cartridges (some Epson, some 3rd-party). I spent half the printing time
switching chips between sets of carts to keep the damed things
recognized, it was no fun at all.
And in addition, clogging was a problem a lot of the time, many many
cleaning cycles. Quality however was excellent when things worked.

With Canon on the other hand, while much simpler to refill and use for
home use (i.e., irregularly), head burnout (nozzles for one or more
colours) is a perennial fear: I am used to cleaning nozzles sometimes
for days at a time to clear old ink, but it happens that still then,
though printing works mechanically, no ink is delivered. In the case
where the printhead is electrically damaged, the printer would give a
printhead error and no longer print (nor scan or do anything else in
that case, damned all-in-one fraud).
