Power problems. It never rains but it pours......

That's a good point. I did wonder whether I was getting a proper vacuum, seeing as I had noticed a slight nick out of one of the corners of the gasket. Someone here commented that they had a spare gasket. I will have to go back and check who, but if the poster in question is still around, would...

I'm afraid I gave up with it :-( I could get the ink to flow briefly (and with an incomplete pattern) by priming as @turbguy suggested, but it would not last. I ended up just forcing the printer to use the Photo Black instead. It increases the length of time required to print by an order of...

I finally got around to doing this! After priming the PGBK nozzles by squirting some ink through, I managed to get a patchy nozzle check pattern, which improved somewhat upon several cleaning cycles. This is positive, because previously the pattern was getting worse on each cleaning after...

Hi, I'm back after a notable absence.... I don't quite understand what you mean here. How can that 7th hole collect/transmit anything when it doesn't match up with anything on the ceramic block? I could just about understand it sinking heat (although don't know how effective that would be unless...

I am reluctant to get yet another replacement print head in case that also fails - at £40 a time it is an expensive experiment! I would like to be able to rule out other possibilities first

After having no success with this advanced cleaning, I tried to rule out printer problems by replacing the head with the original (which had functioning PGBK but faulty colour nozzles). Unfortunately I got the dreaded 'the type of print head is incorrect' message after installing all the...

ok, here are the shots I took when disassembling the print head. The one of the bottom of the head was taken before wiping off - lots of cleaning cycles had produced rather a mess here! I have inserted the images as thumbnails here. If anyone wants more detailed ones I can attach them to...

Oh I took some photos during the process. I will post them if anyone would find them useful.

Well, I finally got round to doing what @turbguy suggested. Disassembling the print head was easier than I thought. I didn't notice any particular clogs, either in the assembly or the nozzle plate, but I flushed everything on the PGBK side out with cleaning solution just in case. Put the whole...

Well I tried it - no luck :-( Having filled a syringe with cleaning solution, I pushed it gently through the PGBK ink port until it trickled out of the nozzles. I then dabbed over the whole head with kitchen paper and blotting paper, and left it to dry overnight. I replaced the head and...

I have run out of cleaning solution, so have just ordered some more which should arrive in a couple of days. When it does, I think I will try to clean out the PGBK passages in the print head. After soaking I always make sure it is properly dry before I put it back in the printer, by using...

Suffering from ink starvation...

Thanks @PeterBJ , now I understand the pattern of missing ink across the page. I always use OEM cartridges refilled by my local Cartridge World branch. I do not know what ink they use, but it has served me well in the past. I have only had two 'dud' cartridges before out of a sample of scores...

Here are two scans, first the nozzle check, then text (from a Windows test page print; the results for text documents such as letters are similar)
