MG5620 PGBK print only distorted

[Geekster]

Hi!  I have a Canon MG5620 printer that started printing distorted in PGBK only.  The vertical lines print as vertical elipses between the second horizontal line at the bottom and the top of the graph display on the "nozzle test" page.  My problem is, can this be fixed or is it time to shop for a new printer.  I can post the print if required.  Thanks for the guidance!

Hi Geekster,

The nozzle check pattern is a maintenance function which is stored in the printer's memory.  Since cleaning the encoder an additional time did not improve the print quality the printer will need to be replaced.

What do you mean by "the nozzle check pattern is a maintenance function which is stored in the printer's memory?" The PGBK image prints but ALL the vertical lines are ellipses. Also the number of pages and version that prints at the end of the nozzle printout are double printed on top of each other. The text printed in the column by the C/M/Y/BK/GY colors is perfect. It is only an issue with the PGBK printing, and ONLY VERTICAL printing.

If this was a encoder strip problem would not all text be off?

This is incredibly frustrating. Our business has over 20 of these Canon MG series printers and several of them have developed this exact same issue. To be told to replace the print head that costs what a new printer costs is nuts. 

I can't believe there is a clear explanation for why this happens. The only reason why there are not hundreds, if not thousands, of people reporting this is that they don't know what to search for to find this thread. I have spend hours looking for an answer and finally found this thread. Most people I bet give up and trash the printer, of course this is what is desired by Canon (new sales).  If we don't find a satisfactory solution we will stop buying Canon printers and ink period.

If someone can find an answer that is NOT to clean the encoder strip (never solved this) or replace the print head it would benefit many, many people.

This happened more than a year ago.  Solution likely involved print head replacement.  Canon makes HP too.  Go with printer with head in replacement cartridge or just go to a Brother laser printer.  I did, didn't look back at wasting ink to clean nozzles, fantastic printers!

this is not a solution unless Canon wants everyone to switch to another printer manufacturer

I see exactly the same problem in MG5650

I am experiencing exactly the same on MG5750. I have wasted a ton of ink cleaning the nozzles, and the timing strip but the issue stays the same. This is ridiculous.

Same exact issue here with my MG7520. I also have changed cartridges and cleaned the timing strip and print head.

This is caused by warping of the PGBK printhead which is supposedly due to overheating of the printhead. I have replaced the printhead when this happens and had the new printhead go bad in just a few days. Don't know if this is because of the printhead heater getting too hot or the heads not cooling because of non Canon ink or printing too many pages without stopping. Supposedly turning on the quiet setting helps by making the printer print more slowly. There are ways to make the printer use the dye black ink to print text but that has to be more expensive. (If there was a printer from another company that would print DVDs I'd switch but no luck at present.
