I recently had to refill Photo Black and another color cause they were low on ink. After refilling them when I try to print a picture where black is next to another color it looks like its smearing some and almost blending with the other colors in spots.

I tried doing a deep clean a few times and cleaning the bottom plate and roller cleaning. when that didn't work I took out all the ink and printhead and cleaned that and then put all the ink back in. Same problem.

I have had this printer for like 3-4 years I believe and use it pretty much a few times a week. I use precision color inks and put them back in the original carts after resetting them. I have been using the drip method I believe its called where I drip ink onto the inkpad to fill it.

Any ideas or help what might be causing this would be greatly appreciated.

Thank you,
Chris

@nasabuzi, your problem could well be a dirty timing strip, the link below will help your find its location and hints on cleaning, please reframe from running more than one Deep clean in a 12 hour period (Very damaging) and leave the print head in the machine and let it do the cleaning for you... Safety First..

The Pro 9500 is one of the great printers, so look after it because it’s irreplaceable...

Hi The Hat thank you for getting back to me. So I just tried cleaning the timing strip some and it looked clean but once I rubbed a Qtip on it with isopropanol black showed up on the qtip. Its not the easiest thing to clean with its location and everything. I have done a few test prints and they look slightly better but not perfect so another attempt at cleaning might be in order.

Yes this is my 2nd 9500 after the first one encountered a waste pad error and had to buy this one, which I am tempted to pick up another one for cheap and start with that one.

The problem looks to me like the black is bleeding into the yellow, so could the yellow or black ink be a wrong type? Maybe dye ink instead of pigment?

Cleaning the timing strip is always a bit tricky and should be done carefully, both sides of the strip need to be cleaned with a paper cloth, just take it slowly.

The reason why the Pro 9500 is a gem is because you can reset the waste ink pads and as long as you have a working print head they will go on for years and years...

I tend to agree with @PeterBJ. Looks like dye ink bleeding when it contacts solid areas of pigment inks, It would be interesting to know if this print is on plain or on photo paper.

Anyway, the OP always uses Precision Colors inks and it seems hard to believe that they put dye ink in Pro9500 bottles, but mistakes happen sometimes. Of course, if @nasabuzzi has previously refilled his carts with ink from the same bottles without issues, then the problem lies elsewhere.

Too much ink caused by a wrong paper type setting ?

Thanks for the help everyone and yea it looked like to me the inks were bleeding together but in only certain spots. The image I uploaded was printed on matte paper with the matte paper setting selected, same as I have done for several years now and this just suddenly popped up.

So I did try using a 2nd yellow cart with the precision colors ink I have and the same bleeding was happening but just slightly. I have a new Photo Black cartridge coming thinking it might be the actual cart. Just trying to sort of go thru this item by item to see what is suddenly causing this.

It’s less likely that the cartridge is to blame, because these things are made so they can’t go wrong, unless of course it gets damaged, did you remember to shake all your refill bottles before commencing refilling, because failure to do so can cause similar issues..

Yes I definitely do a nice little shake for the bottles before filling but next time I will try extra shaking.
