PIXMA MX850 Error Code B200

[grampatex]

Suddenly error code B200 no explanation in manual have canon pixma mx850

[ellis1]

Before getting into the print head cleaning, try just removing all the print cartridges and re-powering the printer up. Hopefully it will go through a complete cycling and come up with the message "can't recognize print cartridge," or something similiar. At that point re-install cartridges, (making sure they all have ink in them) and re-cycle the power. Be sure all the cartridges are pushed down all the way to the "click" and locked down.

If the cartridge ass'y is all the way to the right, just pull gently on the ribbon cable until it's accessable.

Pulling the ribbon cable is very bad advice, think about it. What if the head is jammed or locked, the cable may become dislodged or broken.

A B200 error means 'Abnormal head voltage', visit help and support for your model and check the error code.

There is one thing you could try and appears quite logical,  get the print head in the middle either by doing a 'change cartridge, power ON wait for the cleaning cycle then open the top and remove the plug the hard should be unlocked and freely  moveable.

Removed the print head, with a clean soft cloth moistened in warm water clean the gold contacts on the back, then try again. DO NOT touch, or scratch the print head nozzels on the bottom.

A B200 error usually means a new print head..... you will be very lucky should a new one work, because when the print head goes it sometimes takes the logic board. Should the logic board be faulty 'pop' goes the new print heat.... and these are NOT returnable.

Sometimes a B200 error will pop up and a series of flashes of either amber or green, or amber lights and green might flash alternatively - count the flashes, i.e  the amber or green and amber flashes 10 times, pause and flash another 10 and so on until the printer is powered down.

The correct way to release a print head is to turn the large gear on the left hand side, this unlocks the head parking unit, the head can then be easily slid by grasping the head unit..... not the ribbon cable. Sometimes the wiper breaks off and jams the head, this will also cause error codes.

how to solve printer

[Chromejob]

I've registered here to post about my recent experience with a Pixma MP620 that I've had for years (very light use as a scanner and printer, ink always kept supplied).  I recently refilled all the low tanks,[1] and after the last "fill-up" did a deep cleaning to correct some alignment issues. Test print page was perfect.

Yesterday while printing a PDF, I canceled the print job from the Windows printer status window, then the Canon print dialog (status was still "Preparing print job..."). Upon examinig the printer, the dreaded B200 error was annunciated.No paper was in the paper path, nothing else out of order. The print head was parked normally.

I've tried a long power off (cord disconnected, 2+ hours), no joy, removed and reseated the ink tanks, no joy, removed and cleaned the print head and ink tank inputs (Qtip and isopropyl alcohol, as I learned working on military grade avionics), no joy, turned the printer back on without the print head and tanks, and installed each as directed by the status window, no joy. Still the B200. I did notice that when I installed the print head there was no error other than "ink tank unrecognized," when when I installed the ink tanks, no further error. I may buy new tanks from Costco to see if that clears the error.

Haven't had any results from magic button combinations.

Following Diane's recipe (I agree, running warm water over an electronic component is ill-advised and probably futile), I'm soaking the bottom of the print head in isopropyl alcohol three times until the alcohol remains relatively clear. Then, shake dry (no patting or touching), then air dry for at least 24 hours, then blow with gentle compressed air, then ... crossing my fingers ... installing the print head and ink tanks in sequence.

But ... this is why I'm here posting.

I'm here to post to Canon that this is unacceptable and will prevent me from buying your consumer electronics in the future. The circuits need to be sophisticated enough to identify the point of failure (e.g. "print head voltage," "print head ink issue," "self-test failure") so that the consumer can receive a general repair prognosis and estimate from a service center. A generic error like "B200, check manual" leading to "power off, wait 5 minutes, power on, if no change, submit to service center" is useless. The consumer is not a pot of money for you to dip into without prior consultation! ... Particularly when repair or replacement of parts may cost more than a new printer.

This is also wasteful. If I KNEW for certain that the print head was damaged, I'd buy another. But the lack of information leaves me no choice but e-cycle the printer and buy another -- by another brand -- at Costco. Cheap product planning like this doesn't just result in a poor printer, doesn't just result in future lost printer sales, but trickles down to prior customers who become negative ambassadors who shun the brand and encourage others to do so. Save a few pennies on the design and manufacture of a printer today, costs many dollars soon after.

[1] I'm curious if others encounter the B200 error after using third party refilled tanks, or third party new tanks.

Hello everybody,

I don't want to take the side of Canon now, but just to report to you that my Pixma MX850 has been working fine ever since my "treatment" (first post). I can't state what happens with refilled or third party ink tanks because I always use original ones.

[rwrose911]

Nice answer. Too bad it does not work.

[hoffners]

Having the same error as Rick, but our Canon is an MX712. Tried the suggested fix in this post but still have the same error. Please help.

Just to clarify, here is what we did to attempt resolution:

Hello Rick_Ridgeway.

Please try the following to see if we can resolve your issue:

1.  Turn the printer off.

2.  Unplug the power from the printer for at least 5-10 minutes.

3.  While unplugged, remove any paper from the unit.

4.  Double check for any obstructions found in the unit or paper paths.

5.  If no obstructions are found, plug the power back in and turn the unit on.

If the B200 error persists or the tanks cannot be accessed , please contact our support group using the "Contact Us" link below for additional assistance with this matter.

Pixma Pro9500 Mark II - I got the B200 error but the print head cartridge is locked into the right-hand position and I have tried other suggestions trying to get print head to move to center position so i cd remove ink tanks and print head to clean it.  Nothing has worked so far.  Does anyone have suggestions for releasing the carriage so can access.  You cannot pull it over; it is locked into position.  Thanks

[Mandroid]

None of this has worked for any of us. I am frustrated and at the end of my rope with this. Can you please update with a better answer?!

[iamlaurie2]

Canon Pro9500 Mark II - Actually after some conversation with my (not so local) local repair person which led person to believe I could do this (I hv maintained ofc computer system in past), he explained how I cd open printer case (since it was out of warranty and not working anyway nothing to lose) and turn the wheel which is hidden inside case behind the buttons which would release my printhead from being locked to right side of carriage and not accessible.  I followed his directions and was able to release my printhead which I soaked several times in alcohol to clean out the ink - was a lot in there.  But even with it cleaned, I still got error message which he said would mean that my printhead was probably toast, possibly had been damaged beyond being fixed.  So I'm still trying to figure out if it is worth buying another printhead which is not cheap and risking that something else is wrong.
