Top 10 Canon Pixma MP500 All-In-One InkJet Printer Questions & Answers

I think I have come up with a solution!

When the error happens:

Open the cover and re-seat the cartridge.
Tilt the whole printer forward about 30 degrees or more
Close the cover.

This has worked for me multiple times now. I think there is a small sensor behind the contact chip that detects ink levels and when my printer is flat the level of ink is lower than the sensor, when I tilt the printer the error vanishes because the ink covers the sensor. Though I am not sure why the software in the printer determines that there are duplicate cartridges instead of just a low ink warning.

If you still can't get it try taking a standard pencil eraser and gently rub it over the contacts to clean off any oxidation, also do this to the prongs that contact the chip that are inside the cartridge carrier, They bend easily so do it very lightly.

I had the u043 problem on the blue cartridge on my mp830.

I was using non-original replacement inks but re-using the chips from the originals - replacing the blue cartridge would cause it randomly work but i then noticed the chip holder was not centred so I realigned it and hey presto! the problem was solved first time.

When you filled your cartridges were they empty? If so there is a good possibility that the nozzles are gummed and dried up. If you are going to fill them yourself watch the indicator that comes up on the screen it will tell you when you are getting low. If you get a low indication fill it asap. This will keep your nozzles wet and free flowing. Waiting until its empty can cause them to gum up and altimately dry out. My solution is to go to the store buy brand new cartridges. Go through the the full set up that your manufacture recomends. This means using the install new ink cartridge utility that came with your printer. Print a test page and print a nozzle aligment page. Just remember never let your ink completely run out before filling. If you follow this you will never run into this problem again.

For error 5100 try the following, I know it works on some Canon printers:
Unplug printer, press and hold "resume" button, press "power" button and hold down, release "resume", press "resume", release and press again. Release both buttons and now press "resume" 4 times. Power off. Re-start.
Hope this helps.

Other forums report this problem as a faulty ink cartridge that cannot be recognized or gets recognized as the wrong color. Calling canon tech support will usually result in a free replacement from Canon. If not, try purchasing a new cart before ditching the printer.

The gray-colored arm (it's not that small) is to the right of the cyan cartridge. It is the arm or extension of the gray-colored hinged cover. Remove all ink cartridges, lift the gray-colored arm up, and pull the print head out. Clean the print head with a cotton ball soaked with water or rubbing alcohol. Dry and re-install the print head.

I had the same problem. I was using original brand cartridges and it was still not working. Here's how I got it to work. I recommend doing each step and then trying to print a test page to see if it is working.

1. I used a Q-tip with Isopropyl Alcohol and cleaned the gold contacts on both the cartridge and the mating contacts in the printer.

2. Then from the Setup Menu, I found a menu called Tools. From there I ran "Align Print Cartridges".

3. From the same menu I also ran "Clean Print Cartridges"

4. I then ran a few test prints by going into the Setup Menu and then choosing "Print Report" and then selecting "Self-Test Report". It prints grid patterns in black & white as well as magenta, yellow and blue. The black grid pattern had some missing lines until I printed this report a few times.

5. I made a few photocopies and now the printouts no longer have large stripes of missing ink as it did in the earlier steps.

Good luck. Hope this helps.

After removing all the ink cartridges, I removed the print head and soaked it in propyl alcohol overnight. Then blew it out gently with an aerosol 'air duster' and washed it again in fresh propyl alcohol followed by another blowing out. After gently blotting the print heads on a soft tissue and replacing the print head plus cartridges, it necessitated two deep cleans to get the inks through and all now works again.
Make sure that you switch off the printer at its On/Off switch and not at the supply. I think I may have done this and left the heads not parked properly - hence the drying out!

Cleaning your head might resolve your problem. Perform the below steps to clean the head:

Print Head Cleaning / Head Refreshing If the printed nozzle check pattern is broken, missing, or a specific color is not printed, clean the print head (Cleaning) or print head deep cleaning (Deep Cleaning). Note:

1. Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount of ink in the ink tanks.
   
   
2. Print head cleaning is performed when you connect the power cord. Your machine may perform print head cleaning periodically to avoid clogging.
   

Overview:
Step1:
Print the Nozzle Check Pattern.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is poor, perform print head cleaning.
Step 2:
Perform print head cleaning.
This unclogs the print head nozzles
Print the Nozzle Check Pattern again.
To check whether the print head nozzles are clogged, print the Nozzle Check Pattern.
If the print quality is still poor, perform two print head cleanings.
Print the Nozzle Check Pattern again.
Step 3:
Perform deep print head cleaning.
This is a more powerful cleaning.

   Do not do any other operations until print head deep cleaning is completed.
   
   
   
4. Print the nozzle check pattern and check the print head status.
   
   Note:
   If the printed result does not improve even after doing print head deep cleaning, turn off the printer. Then, after 24 hours or later, do print head deep cleaning again. (After a given time interval, ink could dissolve itself, resulting in ink unclogging.)
