MG5620 PGBK print only distorted

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!

Re: MG5620 PGBK print only distorted

All of the pigment ink based printers can suffer from a clogged print head due to dry ink and clogged nozzles.  Cant say  this is your issue 100%, but its a good place to start when print quality starts to diminish.

 

You can use instructions for 5460 on the 5620...  see these posts:

Rick, thanks but I don't believe it is cleaning.  This is not a random thing, the vertical lines are almost perfect ellipses with some distortion in the horizontal ones.  Several prints show the exact same pattern, even when laying one over the other.  I have used the clean, deep clean, even took out the printhead and washed it all out.  I believe the printhead is OK and that the flaw is either in the hardware or the software.  Nothing random here, looks like intelligence involved.  Might be time to shop for a new printer but I really liked this one!  Have lots of extra ink too.

Hi Geekster,

 

Could you please take a picture of your nozzle check and attach it as your next reply.

 

We look forward to your reply.

Hi Geekster,

 

Based on the nozzle check pattern you provided, it seems that the encoder strip inside the printer needs to be cleaned.  Please click HERE and follow the steps to clean the encoder strip.

Re: MG5620 PGBK print only distorted

George, thanks for your help!  Well, I cleaned the encoder strip again, first thing I tried, only this time I made swabs from pencils and soft cloth, one with alcohol and one dry.  I thoroughly cleaned both sides of the strip and examined it carefully for flaws, and as far as I can see it is clean with no damage.  So, I printed a nozzle check page and laid it over the old one on a light table and it is exactly the same.  Surely if it was the strip I would have changed the pattern somewhat.  I don't understand the printer's use of the strip, is it only for the PGBK ink and all others are random?  Sounds to me like there is either a software fault or a hardware fault, but definitely not an intermittent since it is so consistant.  Any other suggestions?  Again, I love this printer and hate to see it go but maybe I'll shop around? 

Geekster, (George as well).

No comments?  Is the printer pretty much toast?

Thanks!

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.
