Canon Pixma MP530 AIO Inkjet Printer Error U043

I've recently adquired a Canon MP530 AIO Printer after 20 copies or so, a message saying "Without Ink Error U043 5BK C" appeared, according to the manual, I have no ink on both black (big) and cyan cartridges, which is obviously false. I've removed the cartridges cleaned the head, restarted the printer with no head and still nothing. When inserting the cartridges a red light is activated when each one is properly inserted, this happened when I first used the printer. Now they seem to random on/off and there is some flickering at times but I can't get them all on as it was supose to happen. Thanks in advance for the help.

I had contacted Canon to resolve my problem.

Through the technician I am informed that the printer has to be sent back for service as one of the 4 pins on print-head print has dropped off leaving only 3pins that is why the error code U043 simply occur which is why replacing another new ink cartridge does not resolve the issue.

I have understand from him that:-

  1. Most of the time when error code flash up, usually are due to the unique feature that Canon has build on the ink cartridges not properly done which resulted to be faulty. Canon's purpose is to prevent the usage of 3rd party ink cartridges. Of course this causes inconvenient to users, but if users are not using 3rd party ink cartridges, once detected is Canon's ink cartridge issue, do contact Canon, they will provide house call for 1 to 1 exchange for the ink cartridge.
  2. Other times if by replacing new ink cartridge the problem for error code still occurs, it might be the pin on the print-head has lost the alighting, this will require for Canon to service to alight back the pin on print-head in order for the printer to operate smoothly again.
  3. If your problem is like mine, inputting the ink cartridge into the wrong slot, well I guess only have to contact Canon as the printer's components used seem to be highly sensitive, by input the wrong slot would have caused scatches on the pin, well it is better to have the ink cartridge remove by the expert than to DIY. (Maybe check with your own nearby technician if by any lucks they can help to rescue your printer, which I hope Canon does not have further enhancement on their printer with other Unique features to prevent users from using 3rd party technical support.)
I hope the above information will help all the troubled Canon printer users as I notice from previous search on this website, there are other users having problem like ink cartridge is only partial used, but error code appear to check ink cartridge, maybe trying to taking out and putting back, it works sometime and problem occurs again, by replace a new ink cartridge will help as the partial used one would be faulty already, and do call up Canon to report the issue and they will exchange a new ink cartridge for the faulty partial used cartridge.

SOURCE: Canon Pixma ip4200 printer, error 1414

Hello there,

I've gotten in touch with Canon and have something a little different to try. At the very least the error should change. (Sorry, gallows humor). Please read this entire response before taking action.

After the upcoming test procedure, I have included a link and procedure to contact Canon tech support. The assure me they will replace any faulty tanks.

The purpose of this exercise is either rule out ink tanks that are behaving or isolate the one(s) responsible for the 1414. You should write down the results of this test. Please perform the following:

1. Open the printer and remove all ink tanks.

2. Insert a single ink tank in the printer then close the cover.

3. Confirm whether the printer recognizes the installed tank properly. If it does, it will indicate it does not detect the other ink tanks, as they are not currently installed in the printer.

4. Repeat steps 1-3 with another ink tank.

5. If the printer at any time indicates two of the same ink tanks are installed, the cause will be the last tank installed. For example, if you inserted an ink tank earlier, and you later inserted another ink tank, and it said two of the same inks were installed, the cause of the issue is the last ink tank.

Click here for the Canon PIXMA iP4200 support page
Then click on e-mail support.
Fill out the form.
Under description, supply the following info:

Error 1414 Ink tank problem on my Canon PIXMA iP4200
The error won't go away.
I have replaced the <color in question> tank, reseated it, yet the error remains.

You will also need to list what inks are being used in the printer. State the type of ink that is being used and the order that the tanks are installed in the print head.
Provide the exact part number (such as BCI-6C, BCI3eBk, etc.) if possible.

The Canon support rep assured me they will be glad to replace the malfunctioning tank(s) for you at no cost. Please
respond with the results, and specify the ink tank(s) that were not recognized correctly.

They responded quickly, professionally and apologetically. They want to help get this resolved for you.

I hope this helps end the frustration you must be feeling. If you need additional help or clarification, click the ASK button.


If you could take a moment and rate this response, I would appreciate it.

SOURCE: error code: U150 The following ink tank cannon be recognized (Cyan)

U150 ink error fixed!

I too was getting the error for unrecognized ink cartridge. Then the little green circ board fell out of the end of the ink cartridge and it hit me that maybe if I put in the little green circ board from the old ink cartridge of the same color, then maybe the ink cartridge would be recognized. It worked! So don't throw out an ink cartridge that still has ink just because of that error and hold onto your empty cartridges in case you need the little green/gold circ boards.

This works!

Hi jet, I would suggest you update your printer drivers, try this, follow instructions exactly as written:

Create a new folder on your desktop and name it newhpdrivers(substitute your manufacturer in new name). Un-intall printer and printer software completely. Go to manufacturers website and navigate to their drivers/downloads or support menu. Select your model, choose the relevant software and download to the new folder you created on your desktop(watch for the light yellow bar at the top of window viewing pane, click on this and choose – download file - . Power down your computer. Reconnect the printer to the computer and turn printer on. Power on pc. Windows will detect new hardware and ask if you have the manufacturers install cd or a location to check for install files. Direct the wizard to your new software, follow the rest of the setup instructions and your done.

Printer wont reconise ink cartrige

Make sure you've removed the protective tape from the cartridges that you inserted into the printer and that the cartridges were installed properly. Are you getting an error message or is the printer just not printing? If you get an error such as Error U041 or U043, the printer may just be low on ink or have a bad ink cartridge.

Canon mp 530 error u043 cant get rid of it

It is registering a empty ink cartridge. If you had the cartridge refilled instea of replacing the cartridge that is what happened. The chip on the cartridge wont register the refilled ink and tells the printer it is empty.

The U043 error code indicates that an ink tank is not installed. One or more ink tank icons on the LCD should also be lit up. The lit up icon indicates the applicable ink tank. Verify these tanks are indeed fully seated in the print head and that they are lit up red.

You can also press the OK button to clear this message and continue.

MP500 ink tank cannot be recognized error U043

I had the same problem. My mp630 is also only 4 months old. I replaced all colour ink cartrdiges(inc black), but was only able to release the function for detecting the ink levels for magenta and cyan. Yellow and black then started giving error message U043, with them alternating between working, but never working at the same time. Getting them all clicked in with the lights glowing red does not solve the problem, as once the printer cover is closed, the same error message turns up. The only thing that worked for me is moving the chip slightly out of alignment, by pushing the sliding chip holder, and I only had to do this twice before they all started working and the printer was unlocked.
