MG7150 PGBK printing distorsion

TrevorH — Sat, 01 Oct 2016 09:46:47 GMT

I have a problem mentioned in other posts on other printers - but unfortunatey no definite solution. The test print output shows the problem

I have tried cleaning, deep cleaning, aligning, updating drivers and removing the printhead to clean it outside the printer. A possible other solution is cleaning the encoder film.

I can't see how this could be the problem as the print deformation consistant across the page. The encoder runs all along the page also - so the problem with it would have to be the same along its full length? I may be wrong so I will clean it to see if it changes anything. The problem in doing this is access to it. How do I remove some/all of the printer panels to gain access? Any assistance will be appreciated.

I can't understand how the above pattern deviation is so regular? I assume there are 2 printing passes to generate the output. It looks as if there is a progressive delay in pushing the ink out of the head towards the centre of the pattern. This would account for the pattern generated. If it was a "simple" print blockage/restriction I can't understand how it is so uniform?

Any feedback / advice etc. would be welcomed.

I am dissapointed I have not had any replies?

On searching the web I think the distortion is a common failure fault.

My printer is not yet 3 years old! After showing the printout to Canon they stated they did not know the reason for the fault but try cleaning, etc? I approached another company that said it was the print head. With this I again contacted Canon who wrote "Thank you for your email. Unfortunately, we are not able to confirm that replacing the print head would resolve the issue."

I would have expected Canon to have some technical savy - but obviously they don't.

I would like Canon to contribute to the parts replacement/repair as I think it must be an inherent problem with their printer.

If you are thinking of purchasing a Canon PIXMA printer please bear in mind that its life may not be very long?

I've exactly the same problem. I consumed 2 sets of original cartdrige to try to do a good alignement and head cleaning but nothing to do.

Someone have a solution for this problem?

Further to my previous post. After discussions with Cannon. They said "the correct procedure is to approach the actual retailer". I did this and they refunded my original purchase cost - rather a good result.

For me it is impossible because I bought the printer online long time ago.

Maybe the only way is try to change the printhead by myself, I founded it at 36€ shipped from china.

Anyway I forced the settings to print in photo mode to bypass the use of the PGBK ink. Now the text is readable but the printer is so slow to print a single paper and I will be change a lot of normal black ink.

Its so strange that a lot of canon printers have this problem and the solution is just the refund or the assistance.

Are you really used only original ink?

Me too. Canon should be helping us and fix this problem!!!

My printer is a MG7120 but its the same problem. Only switching the paper type to matte photo or high-resolution paper (which stops using the PGBK ink) has worked. This is wasteful and SLOW.

Has anyone found anything else useful?

I ordered online a new printhead in a chinese shop. 33€ I am waiting that it arrive. I tried to clean accurately the printhead un assembled it but the result was just that the printer now print all the colors but the distortions of PGBK is still present and evident.

My MG7120 has the same problem, I was sure it was the printhead so I ordered a new one, but to my great disappointment the problem didn't go away, I used all new ink tanks as well. Might be time for a new brand, and I've used Canons for something like 10 years now, ever since I got my first printer.

I brought up the exact same issue recently on this forum, see http://community.usa.canon.com/t5/Printer-Multifunction-Support/Canon-MG5650-Page-Black-Text-Double-Printing-blurry-text/td-p/217843

This issue only affects when using Page Black ink and when the printer is forced to photo mode and so uses Photo Black ink, the text is sharp - so it's not the encoder strip being 'dirty' otherwise all printing would be affected be text, graphics or photos.

I am wondering it's because I am using non-oem ink cartridges, there is a random counter being triggered by their use, and when this runs down it triggers the print engine software in the printer to mess up the printing deliberately - a bit like the recent Volkswagen issue where the engine management software determines that the car is undergoing an emissions test and so changes the engine characteristic to pass that test! Canon wants you to buy another printer.

Think about it, it affects many types of printer, using a different number of cartridges, so the print heads are different and so therefore the drive electronics all showing the same issue on paper. As other people have said replacing the print head does not make the issue go away.

If it is as you think could be a way to do for example an hard reset or a real factory reset so the printer can restart to print well. On my experience, the first time that I changed the printhead,the printer restart to print well for a very short period,Unfortunately I don't use so much the printer and when I retried after I don't remember well but could be one week the problem restart to be present,so I tried to buy again a new printhead and all new cartridge to be sure but unfortunately the problem isn't solved and now the printer just in the pgbk doesn't print well.

I'll join this club with my MG5450.

My case started with occasional B200 errors that interrupted print jobs. Tried every trick I could find - including thorough cleaning of the print head. No help. So I concluded the print head must be faulty. It probably gets too hot after some printing and then B200 occurs.

Then I ordered a new print head from China -> black PGBK distortion from the beginning. Color printing works fine. Tried cleanings & alignments. No help. Then I temporarily put the old print head back: no distortion. So I concluded my new print head must be faulty. Now this thread gives me hope/second thoughts.

I have contacted local Canon support twice. They just gave the usual cleaning instructions and proposed contacting the (very expensive) service.

I'll soon buy new - most probably a non-Canon - printer, unless the root cause is soon found. Color printing everything is so s.l.o.w.
