Try this:

1. Take a paper towel and fold it over so it is four layers thick
2. Then soak the paper towel in Windex.
3. Then take the printheads from the printer and set them each (jethead down) onto the saturated paper towel.
4. Then press the bottom of the Printhead into the towel.
5. Then add more Windex and periodically press the heads into the soggy towel.
6. Repeat this a few times and possibly let them sit on the towel overnight.
7. Finally clean them off with rubbing alcohol and put them in the printer.

Basically what often happens is the jets with have dried ink on them and Windex is able to clean them out better than anything else.

I want to disable messages about the inkcartridges.


Sadly not. The HP Photosmart C7280 insists on having a full set of cartridges installed in order to print. It does this because the printheads are actually part of the printer itself and can sustain damage if they pull air into the printhead.

The out of date message is also non-negotiable I am sad to say.

Hello there:
This problem is usually due to a print head that needs to be replaced
I have provided the information that you will need ok
best regards mike
This document provides information on how to replace a printhead or ink cartridge.A printhead may need replacing when print quality issues cannot be resolved by cleaning the printheads or a front-panel display message indicates a printhead needs to be replaced.An ink cartridge needs replacing when a front-panel display message indicates either:
  • Low ink levels
  • Ink cartridge approaching expiration date
CAUTION: Never remove an ink cartridge and a printhead at the same time. Use the table below to identify the correct ink cartridge part number: Ink cartridge Part number HP 14 black print cartridge C5011A HP 14 tri-color print cartridge C5010A Use the table below to identify the correct printhead part number: Printhead Part number HP 14 black printhead C4920A HP 14 cyan printhead C4921A HP 14 magenta printhead C4922A HP 14 yellow printhead C4923A Replacing the ink cartridges Follow the instructions below to replace the ink cartridges:

  4. With the ink cartridge label face-up, push the new ink cartridge firmly down into the appropriate slot until it clicks into place.The color ink cartridge inserts into the right-hand slot as indicated by the rainbow colored oval. Figure 4: Inserting the new cartridgec00064459.jpg

Print quality


I have seen where the melted ink overflows and makes the other ink in that color get stuck. This makes it so the ink in that color does not get close enough to the heater to melt the ink sticks. You can try giving it a push from the top of the stack and see if you can get it to break free a bit. You can try this on whichever colors this is happening to. Be very careful not to try and run it too much because the printhead with no ink coming to it can ruin the printhead. When this happened to me however, I had to replace the ink loading station. You might have to call a Xerox certified tech to come out.
Hope this helps

Print head problem


Dear palia1234,
Blinking in orange 5 times indicates that the printhead error occurs. You need to replace the printhead with a new one. But be careful before replacing the printhead, check your printhead if any smoke smell or indication of short circuitry present. Replacing the printhead in this case will harm new printhead. You'd better to take your printer to the nearest service center.

Regards,

Printer Not Responding, 7 orange flashes


Don't replace the print head soooo fast...

Take the print head out first and clean the gold contacts...
I used a very fine sandpaper like emery cloth...

You might get 4 yellow blinks after that.
That is because the printhead was turned upside down to clean and the ink looked low and/or out.

Just wait a few minutes after cleaning and reset...
Mine worked fine after that.... smile....

Well, here is the proper way of fixing or troubleshooting that paper jam error in your printer

Open the printer access door and remove both of the ink cartridge, then remove also the printhead, after that close the printer access door, without those parts. Then it will show a message in the printer screen, "Printhead is missing or has come loose" or "Printhead Not Detected" Install the printhead, just the printhead without the ink cartridges. After that close the printer access door. Then it will show you a message"Ink cartridges is not installed,install ink cartridges". then open again the printer access door, then install the black ink cartridge without the color ink cartridge. then close the printer access door, then message must be " Color ink cartridge is not installed, install color ink cartridge" then install the color ink cartridge." the message must be,"New printhead is detected calibration require, load paper and press start"

Thats the way of overiding the paper jam error message of your kodak all in one printer
hope this will help you guys

Ink cartidges practically full but printer says they need replacing


Sometime the ink dry if you do not use it.....Try this :

Put warm water on a soft clothe and gently press the clothe with the printhead you'll suppose to see ink on your clothe. That's the better way to clean a printhead.

DO NOT SCRATCH THE PRINTHEAD WITH YOUR CLOTHE..
