Re: Canon PIXMA MX922: PGBK not printing

Hi hiker922,

 

Because reseating the printhead and performing printhead cleanings did not get PGBK to print correctly, your PIXMA MX922 would require service. You are eligible for Canon's Upgrade Program.  This is for out of warranty units which have been diagnosed to require service, or for some reason are incompatible with a new or upgraded system.  This option allows you a one-time opportunity to purchase a replacement product, discounted from the list price.

 

To help you get up and running quickly, we also offer free standard shipping (if the order is completed by 12:30PM ET).  If you would like to take part in this option, please call our Sales Department at (866) 443-8002 seven days a week, 8am to Midnight.  Let them know you have been working with technical support and the Canon Upgrade Program was offered.

Re: Canon PIXMA MX922: PGBK not printing

We have the EXACT issue and spent 4 + hours today trying everything we could find on line, including the suggestions above.  Our printer is less than 7 months old.  Very disappointed.

This worked for me:

 

 The two round plastic blobs circled in the photo above must be (carefully) skimmed smooth.  I used my finger nail for this.   The BGBK cartridge then worked just fine.    

 

Reasoning behind my solution? .....

 

In the cheaper copies of the original cartridge, this plastic supports may protrude beyond the green plastic board.  This prevents the 5 rectangular copper contacts from making full contact with their "mates" inside the printer.  Result.... intermittent, little or no printing commands reach the BGBK cartridge and, therefore, little or no printing is performed by the cartridge!

Re: Canon PIXMA MX922: PGBK not printing

Here's the real solution. [Removed 3rd party link per forum guidelines]

 

You need to just flush out the printhead as it's most likely clogged.   You can tell this by taking a damp paper towel and trying to press against the underside of the printhead along the ports (the lines in the printhead).    You should have about 6 short lines in a group (the color printing ports) and then on longer port (the PGBK port).   I could see colors on the towel but nothing, or very, very little from the PGBK port.   

 

When you do this, know that you need to spend some time with it.   Make sure the tap water is hot (as hot as you can stand, maybe wear cleaning gloves) and you need to spend a couple minutes on the foam pads and then rotate and spend a couple minutes on the printhead plate and then repeat until you really see ink coming out of the different printhead ports (lines on the plate).   Again, the PGBK outport is the longer line.     The first time I tried this I didn't go long enough with the water and didn't really turn the print head much to keep working the clog.   After seeing that the PGBK port was still not putting out any ink I really went at it and spent maybe 10-15 minutes just flushing with hot water until finally I started seeing small chunks of black ink explode out of the PGBK port and the associated foam input pad.  Then I knew I was on to something and kept going untill it ran almost clear.    

 

Afterwards, I used some 70% isopropal alcohol from the medicine cabinet to just clean the ports and contacts after drying, thinking this might prevent salts from the tap water from hurting it.   But you're probably fine just shaking the water off and patting it all dry with some paper towels.   

 

Seriously, I can't say enough about how dejected I was until I really tried this and everything instantly started working again.   We almost just bought a new printer which would have been a waste given all the ink I still have.   

 

I really hope this helps someone else who finds themselves in a similar position.
