While I was in the middle of printing a receipt on on my Canon MP970 it stopped and a message said the print head is incorrect. Install correct print head. What should I do please? I am not aware of anything having been changed. Jeremy XXXX
I replied to your question about cleaning immediately and waited for your answer, which never came. I had other things to do after waiting for 15 minutes for your reply. I had already told you that I had not cleaned the machine. Since then I have tried to clean it with no luck.
I followed the programme for deep cleaning. After this I received the same message about installing a correct print head.
The photo magenta cartridge is running out and the cyano cartridge is also flashing now. Unfortunately I have discovered my spare cartridges are faulty. I have ordered replacements. Could this be the cause of the problem?
Thanks for your reply. I am still waiting for the two cartridges so that I can follow your instructions with a full set of good cartridges. I hope they will arrive on Monday but I think I would be wasting my time if I were to go ahead before the new ones come.
The new cartridges came this morning .I now have a complete set of Canon cartridges. I cleaned these as instructed, replaced and switched off and ,after 70 secs, on. Same message to install correct print head.
I have removed the cartridge and the only latch or lever I can see is the one that clicks when you push the cartridge into place and use to release it. There is nothing else that looks as if I could click it without doing damage. I am beginning to think this is beyond me and I shall have to let the printer go to a service shop. I don't even know where the print head is.
I was looking in the wrong place for the lever. I see now there is a grey plastic lever to the right. I have raised it . The empty "stalls" for the 7 cartridges is loose but I don't see how to release it if we need to get underneath. I am afraid of damaging something.
I got it out and there was dried red ink on one of the contact strips (photo magenta?). I cleaned it off but now I am having difficulty replacing the unit. I am angry with myself for not checking how it fitted before removing.
While I was waiting for your reply I found how to replace the object and I am sorry to say went ahead before I had read about the new way to clean. However without doing that I tried a test printing and it worked beautifully. Congratulations. Now I have to shop for some food so I'll postpone the proper cleaning by soaking etc. until I have the time.
Should I also do the prescribed internal cleaning of nozzles?
You have been very good and patient and I'll give you an excellent assessment.
