Hanged with "unknown printer error" LEDs ; doing the 2 button , 1 button
procedure resets something and printer goes back to normal. But for how long
? or is it a page count thing like deemed lamp life "error" on video
projectors, reset there resets the hours counter. Or is it like the excess
toner sensor on a photocopier by monitoring for a sense current through the
rising toner heap . Is a build up of gunk on the sponge falsely saying the
dump tank is full or piping is clogged and producing the error.
Removed the right cheek end and exposed the sponge area and a rocking sponge
carrier mechanism that I've not managed to release. How to go deeper or is
it a matter of just cleaning the gunk off the sponge and suction pump or
similar to empty the sump and check that the silicone tubing is not clogged
(somehow).
If it aint actually broke - don't poke comes to mind.
It looks as though you have to separate the whole underneath plastic section
from the upper metal framework to get to the tank

I managed to unclip the rocking sprung loaded sponge carrier and could then
see the path of the silicone drain tube and hardly a stain on the base of
the sump. Filled the sponge hopper with meths and it drained away into the
sump. So just leaving what sort of reset does that button pushing sequence
produce ?

Hard to tell. Were you able to do some kind of reset and if so what was
the result?

fossicked upon this on www but not what it does , other than returning to
functionality

green (power / data) and red (ink / paper feed) lights flashing alternately
:

1. Switch off printer with panel switch.
2. Switch off printer at mains switch - leave off for 20+ seconds.
3. Hold down roll feed and sheet feed buttons.
4. Switch on at mains.
5. Switch on at printer panel.
6. Continue to hold down roll and sheet feed buttons until both green and
red lights flash together in synchronisation, not alternately.
7. Switch printer off and then, after a few seconds, on again at mains
switch. When red and green lights are both flashing in synchronisation,
release the roll and sheet feed buttons.
8. Immediately after that, press and hold down the ROLL FEED button (the one
at the extreme left) and keep it down until the machine finishes whirring,
cleaning etc and the green light comes on steady - process takes more than
30 seconds
9. Release the roll feed button and all should be well.

Well I would assume the procedure wipes volatile memory and restores
that to factory from a ROM. That is if the printer has some settings
that can be stored. If not it might just reset a page counter.

Likely a processor halt of some sort; most likely culprit is the
power supply filter capacitors, as usual.

I don't think this model has any sensor for ink-dump-full.
If lubrication is needed, it MIGHT know that the carriage
has stalled.

This model has an optional Ethernet, as I recall, and there's some
long menu-setup available (hold the magic buttons and it prints
a menu... takes lots of paper to do a full setup).
