iP3000 Print Problem

[ghwellsjr]

In the first post, he said he's changed cartridges (Canon OEM) when the problem with the yellow not printing first started. But then the yellow got contaminated with magenta so he's probably changed the yellow again. But since the problem switched from yellow to magenta, he has not indicated if he has replaced any more cartridges. With all the cleanings he's doing, he's probably gone through a lot of cartridges. In post #8, he indicated that he refills his cartridges so maybe he's having a problem with the way he's refilling, maybe overfilling or needing to purge his cartridges.

In fact, that gives me another idea: laserguy, why don't you simply swap your yellow and magenta cartridges. Of course the printer won't print correctly but it won't hurt anything and you can see if the problem then switches back to the yellow nozzles, keeping in mind that your yellow nozzles will now print magenta and your magental nozzles will now print yellow.

By the way, this is one reason why I like these printers that don't have chips in the cartridges. You can do a test like this with no problem. The printers with chipped cartridges will know that you have interchanged two of the colors and will refuse to print.

The carts in the printer right now are a brand new full set of oem Cannon's. The original set of oems' that were in the printer are the ones I pulled and refilled. The yellow cart that got contaminated was a brand new yellow oem Cannon. I believe the contamination problem was caused by the color side of the purge unit not working properly as noted in my previous post. The ink was sitting on top of the park pad and the yellow cart picked it up in the outlet. The magenta contamination was only on the surface of the pad at the outlet. It was not pulled into the cart. I've since purged that cart and have refilled it. In the meantime I went down to local Office Max and picked up another full set of oem Cannon carts. They were the ones that were installed in my most recent trial. So yes the carts have all been swapped several times and no the problem is not with carts I refilled.

If I swap the carts, do a cleaning cycle to get the magenta posistion with the yellow cart in place printing, won't it still print magenta there due to ink in the print head and won't that contaminate both of those two new carts or do I need to pull the printhead again and completely clean it and then swap the carts?

If you swap the magenta and yellow carts and immediately do a head cleaning, you won't contaminate the cartridges (unless they actually do have something wrong with them, which is doubtful). The printouts that you do may have a mixture of yellow and magenta but all you are trying to determine is if the problem of the magenta nozzles stopping after a day switches over to the yellow nozzles. However, as long as you have brand new OEM Canon cartridges in your printer, it is highly unlikely that they have any problem. I would reserve these tests until after you have done the test that qwertydude suggested in post #2 and I expanded on in post #19. We need to make sure the problem is not related to the rubber seals that the cartridges mate with.

Ok you've totally confused me now. In your #19 post, I got the idea that you're talking about the 4 oval/round shaped seals directly below each cart inside the printhead. I re-read qwertydudes #2 post and that's not what he's talking about. He's talking about a rubber seal over in the parkpad purge unit area which I don't see. I thought the two white porus pads were where the printhead parked itself. Below those porus pads are rubbertrays with holes in the bottom which drain to the ink waste area. I don't see any type of rubber seal that fits up against the bottom of the printhead and seals the printhead when the printer is off.

 

[ghwellsjr]

I'm sorry, you're right, I'm mixed up. You've already done what qwertydude suggested. He's talking about the rubber trays that the two purge pads sit in. The rim of those forms a seal on the bottom side of the print head.

I'm suggesting something different, which is the four rubber seals on top of the print head.

Expanding on what ghwellsjr said about the rubber seal removal. I would like to add that if and when you remove the seals out of the print head you can put them back in upside down that way you can be sure you have a good airtight seal again ( thats only if none of the rubber washers have any cracks in them)..

 

[ghwellsjr]

These are not like rubber washers, although they may look like that. They have a weird shape to them and cannot be put in upside-down.

ghwelljr,

Do you have any suggestions for renewing or reviving the rubber seals?

Something basic is overlooked. IP3000 is a simple printer. The cartridges for IP3000 are very simple too. Most problems can be fixed by replacing ink cartridges with new OEM carts. You may have done it already. The question is if the replacement carts are actually not functional and you end up chasing a ghost. Before you you unscrew those screws think about it one more time. It is extremely unlikely there is anything you can do inside that may fix the problem. It is very likely the print head will be damaged as soon as you unscrew the screws. Don't go that way. Just use another set of OEM carts.
