Came across an error condition tonight and could use some help / advice.
Summary:
Canon Pro-2000 printer. Getting a few hardware errors: EC21-2F53 and EC21-2F51. Got this after installing Canon PGY and a B PFI-1700 carts in the printer. Pulled and cleaned (gently) the head surface (a good bit of ink on the substrate plate holding the heads) and reinstalled. Still not budging. Did order a new PF-10, but hoping that there may be a few things to do in the mean time.
Detail:
Got a used Pro-2000 from a guy that was moving onto other hobbies. About 2000-ish prints (per the printer status panel). He had been using 3rd party ink refilling the PFI-1100 carts and telling the printer to ignore the chip warning. Did several sample prints and all seemed to be fine at the time. Moved the printer to my house, set it up, several 8.5x11 prints later (using the USB printing the PDI chart) showed that the printer was functional.
Weighing all the carts showed that there was some ink in all carts EXCEPT the CO tank. It was dry.
Over the past weeks I’ve been ordering and installing PFI-1700 Canon official inks and finally got the last two in today. I agitated the tanks before putting them in the printer, and loaded a 24” RC Luster roll in ready to start a few more tests (and to help flush out the old ink). That’s when the fun started.
Upon starting the printer, I got the EC21-2F51 error. So I did as instructed — printer off, waited for about 3 minutes, printer back on — same error. After a couple of other restarts, I tried to print another sample image from the USB stick and now I get the EC21-2F53 error.
I pulled the print head, gently cleaned the print head surface (not touching the print nozzle areas), inspected the metal contacts, reseated the print head and the 2F53 error now constantly appears.
Googling around and looking at the forums on DP Review, Luminous-Landscapes, and the JToolman FB group, I did not find similar hits or issues.
What I am thinking is this:
1) Did Air get in the lines from me agitating the ink and putting it in the printer and then trying to get a test print out quickly? (BTW, when I did select to “change the head”, it did an ink purge, and this did not reset the issue)
2) Given that there was non-OEM ink in the immediate reservoirs, would there have been some reactions (gelling, interactions) that may have interfered with the printhead?
3) is there any other “resuscitation” processes that I can to do clean the head, or further purge the lines?
4) is there any other service menu that I can get into that may help diagnose or reset the issue?
Any and all advice is welcomed!
Thanks in advance
