WE HAVE A KODAK ESP-3 AND HAVE PUT IN NEW INK (BLACK) AND IT WON'T PRINT. THE COLOR SHOWS EMPTY BUT IT'S ALSO NEW. ONLY WANT TO PRINT BLACK BUT IT WON'T PRINT EITHER JUST SHOWS LOW INK ETC.


First: you need both ink cartridges for the printer to function properly.

Second: You may have a bad printhead, do the following:



Clean the print head then print a demo sheet.

  1. Verify that inkjet paper is loaded in the paper trays.
  2. On your desktop, start the KODAK All-in-One Home Center, then select the Help [?] icon.
  3. From the Help menu, select Maintenance, then select Print head Cleaning. The On/Off light flashes green during the cleaning procedure.
  4. When the On/Off light glows a steady green, press Photo and Copy simultaneously to print a demo sheet.

If the Demo print is bad- IE: no black, blurry print etc., then you may need to replace the print head:

Black ink problem with printout on hp7780


Always try replacing the ink cartridges first.

It sounds like the print heads in the 7780 are bad. Don't confuse the ink cartridges with print heads. The cartridges fit inside the print heads. You will need to change the heads. Here is a link to HP's how-to.

Could have the same problem with the Dell.

Paper is stuck and i can't get to it


Remove the jammed paper. Unplug the printer from the mains and PC. Inspect the rollers, etc for tiny paper piece(s) that may be stuck, or other debris. Try to clean rollers and make sure they are dry.
Keep printer unplugged for about 2 minutes and replug and try a test print.
Also make sure that you have waited long enough for the printer to heat up before giving a print job.
Finally, it could be an issue with the paper sensor. If this is the case, you will probably have to take the printer in for servicing..

Hope that helps!

Can send faxes they can read fine but when i get faxes cant read them about a week ago paper jamed in the roller do i need to clean with what product


I assume you talking about a panasonic DP-190? Do not clean the drum you may gently wipe it down, realize the drum puts the image on the paper, nick it, grease from hands, ,etc will effect copy qualilty. Remove the toner cart. clean any toner spilled. Drum may need replacement, print a toner/drum resupply form to see if the machine prints them cleanly

Streaks though the pages


Step one: Retry the print job The problem may occur only rarely. If you have not seen it in other printouts, try again. Step two: Increase the print quality mode If reprinting did not help, try increasing the print quality mode.

  2. Make sure the printer is selected, and then click Properties .
  3. Select the Paper/Quality tab.
  4. In the Print Quality area, choose the next higher quality setting. If the current setting is Draft, choose Normal. If the current setting is Normal, choose Best.
Step three: Print in grayscale (black area streaking only) If the streaks are in a black area of a black and white printout, change to grayscale printing. NOTE: This step does not apply to color printouts.
  1. In the application you are printing from, click File , and then click Print .
  2. Make sure the printer is selected and click Properties .
  3. Click the Color tab, and select Print Grayscale and High Quality .
Step four: Clean the printheads If the print quality is still bad, clean the printheads.
  1. Make sure the printer is loaded with unused white paper.
  2. Open HP Solution Center .
  3. Click Settings , Print Settings , and then select Printer Toolbox .
  4. Click the Service Tab .
  5. Click Clean Printhead , and then click Clean .
Step five: Align the printheads If the print quality is still bad, align the printheads.

  2. Open the printer Toolbox , and select the Printer Services tab.
  3. Click Align Printheads . The Align Printheads window opens. Click Align .

  2. Open the printer Toolbox and select the Printer Services tab.

  2. Press the Setup button.
  3. Press 1 and * simultaneously.
  4. Look at the color blocks labeled Test Pattern 2. Some or all of them could show white horizontal streaks. If none of the blocks are streaked, the printheads are okay.

I have a Kodak easyshare all in one printer 5100


You need to clean the printhead of the printer to solve that

issue. Because everytime you print, excessive inks are going

to the printhead that's the reason why it's clogging the

system up. That's because Kodak printers is using

"pigments" as inks that's why Kodak printers are producing

high quality prints unlike other printers - a photo printed from

kodak could actually last for about 100 years. Now back to

your issue, you need to clean the printhead from the printer

but not manually. You could clean it by going to the

software of the printer namely the KODAK HOME

CENTER SOFTWARE. You need to click the "?" mark

icon on the upper right corner of the software window then

under the General Links select Maintenance then choose

Clean Printhead. Do it at least twice and then try making

prints. If that still doesn't work try calling Kodak Technical

Support Representative: 1-800-421-6699

I hope I have been some of help. ^_^

Canon PIXMA MP780 - suddenly no power


Mine has the same problem. The only difference is it threw a few errors first (weird stuff like improper cartridge, etc.) and I had to unplug/replug in the power to get it to work. Now, nothing at all. Dead. I really liked this unit too! Always used brand new Canon ink. Any ideas?
