Problems with Matte Black and Grey after cleaning and refilling

Thanks Mike,
Thought they were ready for the Waste bin.

Well got my new printhead, but the problem was still there. I Took the chance and disassembled the printer nearly into it's atoms. And low and behold! There were a few bad solderings where the flex-pcb from the printhead carriage meets the "main"-board. Re-soldered them and re-assembled the Whole bastard, and I now have a working printer and 2 printheads! I guess it's always good to have a spare
Glad I'm an Electronics Engineer though. A damn lot of parts!

Well done!

Thank you, Stratman.
And now to my nexT Canon problem. My 5 year old lens (24-105 F4L IS) has failed. When I bought it, it was close to 1900 USD. Repair is 675 USD and a new is 925 USD. Ordered a new one today - will arrive tomorrow. DAMN YOU CANON!!!

To soften the blow, consider how much less expensive the new lens is in today's dollars.

What a savings!

Wow, we'd love to see the procedure!

Mostly I simply followed the disassembly instructions in the service manual until page 32. Then I had access to the logic board. On that board there are flex-cable connectors the are soldered to the board, and there were the bad solderings. Then the most exiting part: putting it back together Again!

Lars,

Nice repair work sir.

I had my Nikon D800 & 24-70 F2.8 fall and when I opened the camera bag the lens was split in half and the D800 was dead!! Sent it to Nikon repair and after $900 all is good. Haven't taken my Pixma Pro 100 apart yet, but just about everything else!

BTW I am an EE also, design silicon chips.

Cheers,

Mike
