Firstly how many times does it blink. If it's something like 7 times
than it's a waste tank full error.
It blinks orange-green-orange-green, etc.

Burried in there is the service manual, which does contain the blink
codes. But if it never stops, that's a "rom error". I've not even
met the rom or the system board personaly, but even if I have and I
could say it was socketed, I wouldn't know where to get the rom in file
form nor does the average person have a ROM burner.. with the exception
of their motherboard.
The blink codes are also listed on this site

To double check you "could" try going into service mode via the
following procedure, with the USB cord disconnected in the unlikely
event there is an issue with the PC's usb.
------------------
I. Make sure the printer is off but is plugged in
II. Hold down [RESUME] (Triangle pointed down) and hold down [POWER]
and wait 5 seconds or so.
Release [RESUME] but Continue to hold [POWER]. Double click [RESUME].
then Release [POWER].
Press [RESUME], than [POWER]. This should cause the printer to print a
simple diagnostic that'll list it's ROM number and list CDR SENSOR=OK
in red for the last line.
Press [RESUME] twice then [POWER]] to print off the second diagnostic.
Press [POWER] by it self to exit service mode and return to being a
printer.
------------------------------------------------------------
This should isolate whether the printer is not printing because it
doesn't want to, or isn't printing because something is wrong. Odds
are it's the logic board, or a connection to the logic board if you
can't get the sucker into service mode at all, or can get into service
mode and it won't print the diagnostics. If you can, odds are you have
a diaper full condition.
If you are curious about worst case scenero, you can ask about
"QM2-1548" the main logic board. How much it costs to replace, or how
much it costs to get. But odds are if you do have a failed logic board
that looking for a used ip4000 with a bum head, and using your head is
a viable solution. Or, buying another printer, cleaning up your print
head, and selling it on e-bay. I don't know if this is your problem,
but given the ip4000 sells for $100 to $150 on closeout sites, and a
new ip4200 runs about $80... if your printer is toast parting out and
buying a new is often most cost effective, and does someone a favor.
