Canon i550 Printhead

[Copy link]

Post time: 2010-1-30 10:22:17 |Show all posts
I have a Canon i550 which died all of a sudden with the 7 orange flashes. I have soaked the printhead overnight in hot distilled water but this seems to have had no affect. When I put in the printhead and switch the printer on I immediately get the 7 orange flashes - how can it tell so quickly that there is a problem with the printhead? Could this mean its burnt out? I have tried running the deep cleaning cycle, realining the print head etc but none will work. Do you have to reset the printer in anyway after removing the print head. I fear I will be investing in a new printer......

Had the same issues as everyone else, 7 orange lights on the I550. Tried everything, nothing worked. Emailed Canon and to my suprise, this actually corrected the problem.
Good luck,
Please follow these steps for isolating and resetting the printer:
1. Open the printer's front cover, and then open and close the print
head lock lever (do not remove the print head).
2. Make sure all ink tanks are seated properly.
3. Make sure all packing materials have been removed.
4. Make sure no paper is jammed in the printer.
5. Disconnect the printer cable from the printer.
6. Close the front cover and turn the printer off.
7. Unplug the printer from the power source, and then plug it back in
after 30 seconds.
8. Power on the printer.
9. Attempt to print a Nozzle Check pattern by holding down the Resume
button until the Power light flashes twice.
10. If the error returns, the printer will require service.

To remove the printhead ...
1. Remove all the ink cartridges.
2. lean the print head towards the front of the printer.
3. Raise the print head out.
Note: the printhead is the device that the ink sits on, not "in". It's the piece with all the foam recepticles.

Dear Canon Tek.... I don't know how to remove the print head to wash it under water... I couldn't find any instructions in the manual or on the Internet. If you have time for a simple explanation, I would really appreciate it. thanks and have a grea new year.

I'm having the yellow button flashing 7 times problem...which I understand is the printhead...I'm willing to try to wash the printhead but I'm not sure what part of the printhead I should run under water...is it the 4 spots where the inks flows or the bottom of the printhead when it's standing upright which seems to have some ink on the bottom? I don't want to put the wrong thing under water. Please help...thanks, Jeanie

I had similar issues with my i550. My ink was full, and although my nozzle check patterns printed ok, the print head alignment patterns wouldn't ("C" pattern only printed the top half of each pattern, the "E" pattern wouldn't print at all, and "F" pattern only printed top half).
I first tried soaking the printhead in warm water. That didn't do anything. I tried the Windex soak three or four times. Again no help.
I finally got fed up and just bought a new printer. I would have bought something other than a Canon this time around, but Canon is still the best IMO. HP stinks because of high ink prices and the fact that their printed photos smear like crazy with even a little moisture. Epson, I wasn't impress with their resolution. So I bought myself another Canon (MP960) and it works great!!! What I found really impressive is the automatic duplex printing. That will definately save a lot of paper, especially around tax time!

My Canon i550 has stopped printing magenta and yellow correctly. I tried the warm water treatment and also the EEProm resetting, but even after more deep cleaning cycles the magenta and yellow start to print the nozzle check pattern but soon appear to run out of ink, even though I can see the liquid ink in the cartridges.
Any ideas?

You don't need to drill. On the top of the tank (on liquid side), peel back the label and you will see a little plastic ball bearing plugging a hole. Take a push-pin (the ones for cork boards) and pry the ball out. That is where you fill your ink.
Some refill instructions tell you to fit the syringe tip into this hole and hold the tank upside down (syringe pointing up) and fill the tank. I find this to be really messy because the pressure builds up inside and eventually just starts pouring out.
I just take a syringe and needle. Hold the tank with the label/hole up, and squirt the ink into the hole. To plug it back, I use a small set screw with an allen wrench. Hope this helps.

On the pixma 1700, I worked for canon technical when they were unvailing the pixma line and that was the first question I had for me. They had no answer. We got a ton of calls on those, people saying that they were missing the tray and wondering why their papers were flying all over the place. $35 isnt too bad for them, I think they retailed for about ~80. They were given away with about every new computer sold for a long time.

Hi All, I need help on refilling the BCI-3e carts on my Canon S750. My instruction kit is not much help. Do I drill and fill on the liquid tank side at the latch end or drill and fill on the foam/felt side at the discharge nozzle end? I tried drilling on the latch end and ink poured out of the discharge nozzle. I must have opened the air vent or something!
I need ideas to fix my daughters machine that now prints all but black. How about filling the non-black carts with black ink and just don't print any color? Thanks JQC

Well, so far I've tried cleaning the printhead per CanonTek's instructions, without success, then reinstalled my old Lexmark 3200 (had a good black cartridge, but color was out). Then I found a Canon Pixma IP1700 and bought it new (spent about $5 on gasoline), unopened for $35, but also found out--after getting it home--that it has no output tray and uses a tricolor cartridge different from i550. How in God's name--and I'm an atheist--could anyone make a printer without an output tray?
I have had Canon products for many years, esp. cameras, and they have been great and I loved my i550, but the lowest price printhead I could find was $62.50 plus shipping of about $9. Outrageous for a little chunk of plastic and metal with some circuitry. The heads are precision made, of course. Anyone know of a refurbishing facility for them?
My time is, of course, worth a lot more than what I'm putting into this, but I used to work for another printing company named Xerox and am now a retired systems engineer. I am now thinking about soaking the printhead for another day in alcohol/distilled water, then letting it dry for a couple days to see if that works. In the meantime I'm setting up the 1700. What the H--it was only $35.
The big problem may be getting rid of the i550 shell in which all the mechanical parts seem to be working just fine. And, anyone want a used Lexmark 3200? It has always worked just great, though it makes a fair amount of noise and is no speed demon.

Hey, you wouldn't happen to know where I can get a replacement s520 print head for cheap, would you? i just thought you might, as you are a service tech...

Post time: 2010-1-31 15:26:28 |Show all posts
does anyone know what to do when the LED is not blinking but
flashing orange only all the time (no green inbetween)?
Best regards,

nice to hear I am not alone with my problems. I also have a Canon
i550 which suddenly didn't print anymore. I then disassembled the
printer, cleaned the printhead with distilled water. After
reassembling the printer, I tried to print black only for the
first time, the printer seemed to work but no ink got onto the
When also trying the other colors using the nozzle test in the
printer settings (Windows ME), the printer made a painful
scratching sound and beeped. This was very unfortunate
because the routine said that the task should never be
interrupted. - But I had no choice, I immediately pulled out the
power cable. I remembered that I had forgotten to install the
little spring on the right edge of the ink-soaking cushion below
the printhead. The current situation is that when connecting
the printer to the power cable, the orange LED is flashing
continuously without blinks. Pressing the power and
resume buttons to get into service mode produced no
results. Also removing and reinstalling the printhead
doesn't help in contrary to past attempts where that worked.
Does anyone know a possibility to get the printer out of
that state to be able to enter service mode and reset the
waste ink counter or flashing the EEPROM?
I would be thankful for any help,
best regards,

Canon tek you are a saint,
tried your method and it worked
had to do it twice but who cares
tip: I used a hair dryer to dry the print head after rinsing the ink holes clear. Medium heat gentle air

First of all thanks to Canon tec and others who have contributed to this thread. I too had the dreaded seven orange flash error code on my i9100. I tried all the suggestions many times and once got printing for 15 minutes, but then the dreaded lights came back. Somewhere I read that someone put his printhead in the freezer for three days. I thought that was a bit odd but got me thinking about the possibility that my printhead had overheated - its carriage managed to jam on the CIS tubing and resulted in the dreaded seven oranges. If the head had got distorted it was just possible that a low temperature might contract the distortion. I put it in my fridge for a couple of hours and the printer sprang into life for a short while. I took the plunge and put it into the freezer for half an hour – and amazingly its been working for over a week now. It would be interesting if this works for anybody else and what the explanation really is.

I doubt that any printer with 7 orange flash lights after a long time use(mine is over 3 years) will come back. If there is any, pls let me know.
I got my canon s520 work again only on the black color after the soak and dry treatment. But the color seems stopped working even the ink is going very well. And it sound all right, even great. but just not color on the paper at all.

When I follow your instruction to go into the support mode I still see blinking 7xorange and 1xgreen. Do you have an explaination?
Many thanks
