Refilling Ink in Canon Pixma MP830

I refilled the black cartridge and the printer seems to resent it! Kept sending "low ink" message, but I could override that (there was a 'print anyweay' option). But now I'm getting message U130: "remaining level of ink cannot be correctly detected." And I can't find out how to override it. Must I forever pay ruinous prices for Canon cartridges?

    JTRA, you said "you can reset the ink counter for the black ink cartridge through the printer properties/maintenance or by simulating replacing the cartridge again."
    Where is "printer properties/maintenance" and what should I do when I get there?

    Re simulating replacing the cartridge again,
    I did multiple simulations of replacing ink tank, also wiped chip down w/alcohol in case there was dirt o it. No progress. I put in a brand-new Canon tank--no progress, but at least I could tell the printer to go ahead anyway by pressing OK. Then the color tanks needed refilling, and that caused the same problem. Now I get message U130 saying ink level cannot be detected, and I can't find a way to override.

    Thank you so much for that info about pressing the reset button for 5 seconds or more. Wow! That really worked. I was getting really frustrated.

    thanks again.

    Having the same problem with a pixma 600.Brand new cartridge, but "The remaining level of the following ink
    cannot be correctly detected. Replace
    the ink tank" . 
     It's great that we can ignore the alarm by holding the reset for 5 seconds, but now that means that it's ignoring the problem and may now damage the print head right? How can we fix the problem rather than ignore it?

    You should be able to override this and tell it to use it anyway. Compatible cartridges for override assistance.

    My Canon pixma ip90 printhead is new, ink cartridges are full, but my printer doesn't work.
    Any ink is blowed on paper sheet.
    The printer has correct sounds and printhead movements seem regular.
    What I can do to configure printhead correctly?

    My 6 or 7 year old iP6000D printer has been a real champ until now. When "Print" activated it goes through the motions of printing, back and forth with slow feed through the printer; however, there is not a single pixel of ink on the page. No error messages appear in the LCD display and I'm still using Canon inks - no refills of any type. I've run all the Tool Box tests, still no ink (and yes the cartridges are full to nearly full. This problem occurred without any warning - it worked one day and didn't the next. I love this old machine but I currently have my eye on a new Epson printer if this one can't be salvaged at a reasonable price. Thanks for any help you might provide.

Hello, I found this in a repair manual for the MP830. summery is to press and hold the stop/reset button for 5 or more seconds. I copied the info from the manual too. The remaining ink amount unknown. [1683] (Applicable ink tank icon) The remaining level of the following ink cannot be correctly detected. An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one. Printing with a once-empty or refilled ink tank can damage the print head. If printing is continued without replacing the refilled ink tank, press the Stop/Reset button for 5 sec. or longer to record the use of a refilled ink tank. Note: After the above operation, the function to detect the remaining ink amount is disabled.

When you replaced the cartridge, did it ask if the color and black ink was replaced and did you answer yes for the black ink only? Either way, you can reset the ink counter for the black ink cartridge through the printer properties/maintenance or by simulating replacing the cartridge again. There shouldn't be any issue by not using canon cartridges.

Canon pixma mp150 printer shows error E 2 7 and alarm light is on also cartridge holder is stuck on right hand side and wont slide to the left

If you are able to produce a self test print, this is good since it illustrates that the cartridges are electrically stable...if you observe any 'E' or 'V' error states (i.e. "E xx" or "V162" for example), this may indicate there is possibly an internal electrical problem with one of the ink cartridges. Refer to your user guide if E/V error messages are displayed.

Inkjet411 support page on the PG-40 black / CLI-41 color ink cartridge series: :

If, after following the suggested ink monitoring/level reset procedures, you still have an error condition which prohibits regular printing, then the ink cartridge probably has internal electrical damage (micro-electronics failure); such a failure is unrelated to the ink cartridge refilling process. Typically, when the cartridge fails the problem is 'masked' by the ink out/empty condition so it can be difficult to distinguish between the two. Many cartridges eventually do encounter problems or failures, especially after their original ink is gone and they are re-used, and this is often unrelated to the refill process (i.e. typically ~2 years from original manufacturing date). Refer to picture at bottom of this page:

Canon 30/31/40/41 - Refilled Cartridge Activation Instructions:
Canon 50/51 - Refilled Cartridge Activation Instructions:

If, following a reset of the printer via the 'Stop/Resume' button, printing is permitted but the 'Ink Low' indicator continues to be lit then one of the inks cartridges may be suffering from marginal internal electrical performance - a potential failure of the cartridge may eventually occur which will prevent printing.

However, if your printer works routinely after inserting a brand new PGI-40 black ink cartridge in it, then this will confirm root cause of failure as being limited to the ink cartridge iteslf.

CAUTION: Be advised, the use of compatible/clone cartridges (i.e. sold thru the internet from overseas) are known to be problematic and may cause printer errors and/or permanent PRINTHEAD failures. We do NOT suggest refilling these types of ink cartridges.....refilling of Canon original/genuine ink cartridges is only suggested!

Canon 30/31 Ink Refilling Services & Additional Cautions:
Canon 40/41 Ink Refilling Services & Additional Cautions:
Canon 50/51 Ink Refilling Services & Additional Cautions:

If you ever need to purchase a new ink cartridge(s) and are trying to cut costs, we suggest you try a remanufactured ink cartridge from as their ink cartridges typically have the lowest cost in the USA, have a high reliability rating, come with a 1-year warranty and provide free shipping for all orders above $20 (these are remanufactured ink cartridges which have been pre-tested in an actual printer; purchases are only available to USA residents).

Just refill our black ink for canon pixma ip 1200 and it gives out lines in beetwen image. How can i fix? it says it needs to unclogged but i kept cleaning through maintenance tab and result is still the...

Canon recommends genuine canon ink jet cartridges. If you bought a remanufactured ink jet cartridge and it did this, I would return it immediately.

But, since you filled it yourself, there's no recourse with the ink company, I don't believe.

Even if you were successful with refilling, they can only be refilled 2 or 3 times at best.

Cannot send and receive fax after refilling PG-40

I own a Cartridge World ink refilling store and I think that the fax not printing is Canon's new approach to kick out refills from their all in one machines. We cannot reset the ink level indicators on these cartridges and if people can no longer print faxes if their ink says it's low, then they can never use refills if they want to use their fax machine. I think it is also a way for Canon to make more money on their ink sales by making consumers buy new ink before theirs runs out. As far as I know there is no way to fix this problem.

Cannon MP220 displays colour ink vol unknown

For the Canon Pixma MP220, I kept getting a message saying "Col Ink Vol Unknown" after refilling and replacing a cartridge. After reading some of the other responses it appears as though Canon cartridges contain internal chips that prevent you from using them after they have been refilled. However, I tried a few things and this is what worked for me.

1. Insert your refilled Canon cartridge like normal, close the lid.
2. The Error message "Col Ink Vol Unknown" should still appear.
3. Use the "Menu" button to scroll to "Maintenance" (press "Menu" 8 times to find it), then press "OK" to conduct a "Nozzle Check" and a coloured test will print out.
4. The Error message will still appear but you will be able to print using colour AND with black and white. For some silly reason the Canon Pixma MP220 won't print using black and white if there is no coloured ink...

Hope this helps!

Refilled Canon PIXMA MP830 and still get ink levels are low! how do you reset levels

Whoever filled this cartridge for you did not reset the chip. I own a Cartridge World ink refilling store and our chip resetter was about $100. I would not purchase from that particular refiller again because they have displayed a lack of knowledge about their product. If you buy from Cartridge World, they always reset the chips for you.
