i9900 printing problem

[Sam123]

Hi,

It was recommended I post my question here.

Canon's only response it to take it to a service center. I don't believe the printer is worth the cost, but hate to just throw things away
if they can be repaired and used.

Here is the scenario:

I have two i9900 printers. One is mine the other is owned by a photographic associate. Mine works as new.

His printer stopped working awhile (months) ago and had an error message waste tank full

Contrary to the standard response of send it in to a repair facility I was able to locate the information necessary to clear this error and clean the absorption pads.

After cleaning and resetting the waste tank full error the first print came out pretty close with a good gray. I almost buttoned up the printer and returned, but thought I would go ahead and print out an 8X10 of the test image. I had been testing with 4X6. This print was way different with the now continuing deep pink tint in the grays.

It now prints with good detail, light and dark accuracy, good definition between tonal ranges. While individual colors are pretty close, and pure black is good, it can not print gray.

I understand there is only one black and these printers have a limited ability to accurately create gray tones, but my i9900 is able to get close, very slight blue tint, and with tweaking isn't totally horrible. His printer on the other hand has a deep pink tint, that can not be corrected.

I have installed new Canon inks, tried different papers and printer settings, with all the results yielding the same deep pink tint.

I installed the his print head and inks in my i9900 and it prints fine.

The print heads are clean and unclogged, the inks are good, the prints are clean and detailed.

What is left that would cause this completely unacceptable color issue??

Thanks,


Sam

The best thing to do is print a nozzle check, scan it and post it. Then we might be able to get a clue as to what's happening.

Moving friends (A) head to your (B) printer may give some light:

1) the printer pins on B may have carved a fresh clean contact surface on the contact pads of A.

2) removing the print head and/or carts may have permitted the vacuum/air balance of the offending cart(s) to be reestablished.

3) Are you both using the same print profiles when printing?

4) Is A using a recently updated Apple OS, there are problems being reported with the mishandling of printer profiles.

5) the pink cast can be the result of excessive mag/red or insufficient ylw/grn flowing from a cart(s).

6) When you returned A back to A was there an improvement???

7) It is possible that a flaw developed in the firmware code, a bit failure in the eprom.

In Jan, my i9900 failed as if it had brain damage, printing was just OK in plain paper mode, but if I tried to print with any of my profiles the colors were dead wrong. Assuming my printer profile files were damaged I printed from another computer. Same results, this is my first public comment about this bizarre behavior, the root cause may be firmware related for both of us.

The i9900 is a great printer, performed excellently for 6 yrs, I just replaced it with its egregious replicate the Pixma Pro 9000 MkII, Canon added chipped carts in attempt to extract more monies from its customers. The Pixma performs as great as the i9900 and knowing that chip resetters are avialable for its OEM carts and auto reset chip for refillable carts I moved forward without looking back. I use the excellent OCP ink for refilling @cost of $0.25 per cart.

Do note that this printer was part of a recent Canon camera/printer promotion, many of the camera buyers not interested or have a printer have offered the Pro9000 on Craig's list for about $250--your friend should check this out

If and when you discover the cause of this problem, email me, I would love the re-use the i9900 as a backup.

good luck irv weiner

Is your friend's printer plugged into the same computer as your printer? Did you check ALL of the settings in the two printer drivers? It doesn't take a very big change to throw off the grays.

It sounds like you are running his printer with the cover off. I have never heard any evidence of this, but is it possible that there is a sensor "under the hood" that is affected by the absence of the cover and is affecting the color output?

In any case, I would just generate a custom profile for your friend's printer and keep running it.

If you want to sell it, you could probably get more for the used i9900 than at would cost to buy a new Pro9000 (as irvweiner discussed).
