Julian,

in case these ideas haven't occurred to you yet: 

- sometimes perfect nozzle checks are perfect because they don't require a 
sustained ink delivery of heavy loads over a stretch of time.  So you can have 
a partial "obstruction" or not enough pressure in the lines that only shows up 
sometimes under heavy load demands.  

- The ammonia injection sounds good, but before that, have you tried cleaning 
under the heads?  There are two levels to that (!!): 

One is the Windex- (or Fantastik-) soaked  (lintless) kitchen paper  towel 
neatly wrapped to fit in the channel under the heads. The heads are raised 
with the lever at  + , then brought over the towel, lowered with the lever at - 
and manually moved back and forth to clean the underneath of the carriage.

The "advanced" version is to use a pipe cleaner . Leave the heads at +, then 
extend the pipe cleaner wire under the heads so it comes out the other side. 
Using both hands (gently) move the cleaner back and forth. Remove and rinse 
as often as necessary. This has the added advantage of not wasting any 
consumables!! Of course, you can soak the cleaner in the cleaning liquid of 
your choice, too.

Either way, expect to do several cleaning cycles afterwards to get rid of the 
junk left behind by either the towel or the pipe cleaner. The idea is they 
dislodge the hard stuff but leave soft fuzz behind which goes away after a few 
cycles.

Good luck - and whatever you do with the printer, enjoy the wedding and your 
time in Sicily (and, come on now, aren't there other cameras besides the 
Holgas that would qualify as "not having a camera"? <g>).

Cheers,


Antonis
