HP DeskJet 660C
 

Found one dumped and as i don't use one and never used one thought
i'd have a go repairing or at least learning something about
these things.
As stand alone not connected to pc it powers
up , lights come up and seems to go through a self
check routine. Pushing power-off and it parks
up and powers down. Flashing Yellow LED presumably
indicates paper out whether a sheet in and grabbed by
the drop down black plastic bar mechanism or at
entry only. I cannot find what senses paper-in.
If while switched off and i manually feed a sheet in then
it will eject that sheet after selftest on power up but
not register any sheets under it.
There has obviously been a flood of green? dye
at some point, not over any circuitry or lines.
Green?, as dye heads are present , one is black and the other
yellow+red+blue.

You are probably getting ink errors of some sort.

Not sure about the 660C but just worked an 825C that it seemed like the
cartridges were bad based on the self diagnostic and test page (see the
HP site on how to run these). So I tried to replace the ink cartridge
with a generic that works in my 827Cse and listed as working for the
800 series but got that flashing yellow light.
I Freecycled this and the guy I gave it to said it worked fine after he
put in new OEM cartridges.

The green ink has come from a small tank with a sponge immediately
next the parking area. Presumably a test squirt point for all inks.

The black cartridge has ink in it by shaking.
The color/colour one seems empty by shaking.

I assume just the paper-in sensor at the top and
if fails to complete self-test, yellow flashing LED
then it will not grab a sheet. So no paper out sensor as such.

This HP support site seems to support the theory that it's a ink
cartridge recognition:
http://h10025.www1.hp.com/ewfrf/wc/d...cname=bpd04230
and you're right that sponge catches the ink when it does a cleaning
cycle. Can you get your computer to recognize the printer? If so what
does the utility say is the status of the ink cartridges? I've hear
there are chips that can be hacked. There are sites that talk about
this for making a printer continuous feed.

I cleaned the active micro-perforated bits of black and colour cartridges
and replaced them, powered up and yellow LED stopped flashing
so i held down the 'resume' button for 5 seconds and the
machine printed out a black test page.

I'll have to now connect to a pc and also find out about refilling
the cartridges
