    My i9950 printer prints cyan cast on photo paper but seems to print OK on plain paper.

    i would appreciate any help.

    I had the same problem 3 years ago on mine and got no useful assistance from Canon tech Support other than "a fault is likely... ... send for service". However the fault apparently rectified itself, but has now started recurring. I have tried altering settings but can only get "normal" looking prints by selecting "plain" paper - selecting "matte" or "glossy" results in prints with distinct cyan colour cast. All prints remain dense and sharp and nozzle check confirms all inks can print OK. Not much consolation I know but seems to be a similar fault.

I had the same problem. Having checked other websites I came across the following which narrowed down the problem to the Photo Cyan / Photo Magenta ink tanks, and replacing the Photo Magenta one (although it was not empty) has successfully resolved the problem. Eveidently ink from the original one was not flowing and so caused the syan cast. (I experimented by subsequently removing the Cyan one which produced prints with Magenta cast)

TEXT OF POST I FOUND:-

That post is labeled "Cannon (sic) S9000 Print Head" and concerns a greenish hue error in all print quality levels OTHER THAN plain paper. In other words, all output designated as Photo Paper Pro, Glossy, High Resolution Paper, etc., results in output with enormous and unacceptable levels of green hue. All output designated as "Plain Paper" whether the output actually is on plain paper or photo paper pro, turns out well.

This problem is not unique to the S9000, as I experienced it identically with the S820 and predictably can occur in any printer with the six cartridge print head.

It is a frustrating problem because you know that the printer is physically capable of printing WITHOUT the hue (as it proves to you each time you choose a "plain paper" paper setting.)

Troubleshooting by reinstalling and updating the printer drivers, and uninstalling/reinstalling the ZoomBrowser EX, replacing the ink cartridges, and deep cleaning are all blind alleys.

A call to Canon support solved the problem for me with this simple and important revelation:

The Plain Paper setting is unique in its use of only 4 of the 6 cartridges. In the Plain Paper setting, only the black, cyan, magenta and yellow cartridges are utilized. The Photo Magenta and Photo Cyan are not utilized. In all higher resolution settings, i.e., in all other settings, all 6 cartridges are utilized.

It follows that if one's problem disappears when not using these two Photo cartridges (i.e., when printing at the Plain Paper setting), then the problem lies with these cartridges.

(In my case, I'd loaded a plain "Cyan" cartridge in the "Photo Cyan" slot during earlier trouble shooting and had forgotten to replace it with the proper Photo Cyan cartridge.)

Problems with magenta hues would admit of the same solution.

Hope that helps anyone else out there tearing out their hair trying to troubleshoot this. "

I have solved the cyan cast problem with my i9950 printer. The fault lies in the fact that the ink absorbant pad in the base of the machine is saturated with ink and in the printer mechanism there is a fan that pumps the excess ink to the ink pad. The result of this is that ink is being vaporised in the machine and it gets coated all over the circuit boards. Some of the circuits are so close together that ink joins them up, especially at the connectors. I removed both circuit boards and cleaned them with proprietry cleaners, re-installed and the problem was gone. I have now removed all the ink pads in the base of the machine and also eliminated the ink pump. I now have a small hole in the side of the printer for a small tube. The waste ink now travells down the tube and into a container to be emptied separately. Hope this helps.

Canon i9950 inkjet printer, keeps showing paper jam even though nothing there. If I turn it off and on, it prints anything from 1 to 4 pages before error message paper jam again. Just going round in...


Maybe it's just one small paper.
If it's on guarantee, take it to store, and describe the problem like this:

"Cant print. Don't know whats going on!"

So they don't charge you ;)

If it's out of guarantee, try to open all parts until you see the small paper.

Or it could be the sensor (piece of plastic) that was jammed, or get jammed when paper pass. Take a good look on that too.
