Canon 9000 mark ii leaving ink trails on sides of prints.

[albeitcrazy]

I have two Canon 9000's and a few months back I started getting ink spots and lines on the sides of my prints. I called tech support and they had me set prevent paper abrasion. this helped for a short time, but the quality of my prints suffered. Then the streaks returned. I called service again, went through all the cleaning software options and was told it was the print head and they sent me a full replacement. Now my second 9000 is doing the same thing, so I cleaned what I could and popped a new print head in. Problem was not solved. So apparently it was not the print head and now I have wasted my spare print head by opening it. (Any way to salvage it?)

The forum won't let me include a pic of what is happening. Any advice would rock. I am refilling OEM carts with OCP ink from R-JetTek.

It's nothing to with your print head but it is to do with a dirty printer.
Your print paper path is probably very dirty. The paper is picking up those nice, fairly regularly spaced smudges.

Run some sheets of blank paper thorugh the printer. You should also run the functions for cleaning your rollers and cleaning the bottom plate. Look in you Printer Prefferences for the 9000 MKII in the Maintenance Tab uper right side of the choices.

You can't go on and on printing without ever doing these preventative steps. Ultimately this is what happens.

Good luck

I have run the cleans several times, both bottom plate and rollers. I have run regular sheets of paper through as well and nothing seems to fix it.

Well those marks are the result of ink buildup. They are not due to mechanical or electronic problems. I also noticed that they tend to occur only on the edges. Is that what you see? Or are they allover the paper surface?
If they are near the edges only then it might be that the paper is slightly curled and you are getting head strikes of some sort.

I'll let the real Canon experts here give you some other ideas.

The Hat and Mikiling will be able to help.

I have run the cleans several times, both bottom plate and rollers. I have run regular sheets of paper through as well and nothing seems to fix it.

You problem is not caused from the platen area been flooded with ink,
that would only mostly affect the back of your paper.

The most probable cause of unwanted ink is from your paper not been stored flat, it has curved or curled edges.
Try printing the same Image on the same paper but feed it in landscape and see if there is any significance difference.

It can also be caused by printing in the highest quality setting all of the time where you can get a build up of excessive ink
on the underside of the print head, a badly fitted or leaky cartridge can cause much the same problem..

The paper is stored in a cardboard clamshell flat. I ran it through landscape to no avail.
I always print high quality, but switched out the print head and still had a problem. Any other suggestions?

Have you tried manually cleaning the printer with some isopropanol on cotton buds. I was getting some marks on my MP620 and I did the recommended roller and bottom plate cleans, but The Hat recommended the above suggestion and I was amazed how much ink I cleaned up, it solved my problem. And if you are printing high quality all the time there is likely to be excessive ink around the printer.

Are you using OEM inks or a CISS?

If you have a CISS make sure that the reservoir is not raised above the printer as it will cause ink to flow through the printhead and leave excessive amounts of ink inside the printer.

Get yourself some think not coated (not photographic) paper 400gsm etc.
Then spray some (just very little) water (with spray bottle, windows cleaner works too) onto the paper and be ready to feed the paper for paper abrasion cleaning in the printer.

It will pull push, the paper several times, your printer will as clean as new. Just do not bend the paper in half as recommended by abrasion cleaning. Also make sure the paper is durable enough not to tear when wet.

Be ready to do this quick as wet paper looses durability quickly. I have cleaned my printers this way forever, the standard dry cleaning just doesn't work. And I have no time to disassemble the printers for cleaning.

P.S. After cleaning inspect the paper, there should be no tears, or paper specks missing. If you have any, look inside printer path with flashlight and remove them with tweezers.

Although I've never used this technique I did read that the paper best used damp for cleaning the paper path is paper used for watercolor painting. Makes sense as these papers are designed to have "wet strength."
