I read earlier that black and magenta were printing but not cyan or yellow.....HP says to gently wipe the side of the electronic band but not the bottom, I did all of the above...and the printheads carefully, no change w/ the printout from "clean printheads"...the cyan had an occasional blue line(very fine) and there was no yellow.

So I trickled warm water over the cyan and yellow printheads....then thought what the heck, got a bowl of warm water and swished the printheads half submerged. They print perfect now I have the reds, yellows, greens and all the colors back w/ the clean printhead option and printed a coupon, it was perfect.

I hope it's not a short term fix...I developed the problem when I didn't print for a long time, hope this helps someone, Cyn

BTW, I flashed a light down in the recepticle for the cyan and yellow printheads and they were gunky w/ blue and yellow gook, so I clean that out w/ a damp lint free rag....paper towels shredded and I had to carefully remove the remnants.

HP Officejet Pro K8600 won't print in color, just in black


Ink levels are an estimate. They are approximated according to how much color might have been used. You may be out of all the color inks, they may be dried out or clogged. There should be a head cleaning operation for the printer, but it uses ink too.

How can i check which ink are out


Your printer should have come with a disk. This disk would have installed the necessary program that runs printing jobs, as well as keeps track of the ink level. Locate this program on your computer (may be under All Programs, Accessories under the Start Menu).
If not, Go into the Control Panel: (see below)
carsandcomps_3.jpg



Above, you see "Hardware and Sound"; and below that shows "View Devices and Printers. Click on this. It will then bring you into the below dialogue box, of which shows any and all printers currently installed and which are being used. (see below)


carsandcomps_4.jpg

Once you have located your printer here - (name etc). Go into your Start Menu: In the Search Box at the bottom type "programs"; look for the words "show which programs are installed on your computer", should be the fourth in the list. Below is what the list will look like. Find your printer here to ensure it's installed.

carsandcomps_5.jpg

Once you have determined it's installed, you need to locate the printer program in your file system. Once you retrieve this, click it to open it. The program should allow you to view the ink levels. With most printers, when ink is low it will automatically open a dialogue box showing the ink levels for each cartridge. If you're printer is not equipped with this feature, then the only way to know if any need changed is when printing a document, and any color is not present.
I apologize for such a long response, as I wanted you to know how to access these files. If you are printing, and all colors appear to be present, without fading, or "blotchy" spots, then your cartridges are still good. You should be able to do a print test (calibration or alignment test) to determine this as well.
Please let me know if you need further assistance.

The color cartridges have all been replaced in the HP Officejet Pro K850 now all the pages are printing blank?


Try re-seating the ink cartridges and printing a test page. Those were new HP cartridges, right? Not some garbage from a ink cartridge refiller off ebay?

How do I check my ink levels


Method one: Check the ink levels from the idle screen on the color graphics display Look for four icons at the bottom of the color graphics display. The icons represent the ink level remaining in each of the four color ink cartridges: black, yellow, light cyan (blue), and light magenta (pink). A larger and more accurate view of the ink levels can be displayed from the Setup menu. If an ink cartridge containing non-HP ink is being used, a question mark displays instead of the ink drop in the icon for that cartridge. The HP All-in-One cannot detect the amount of ink remaining in ink cartridges that contain non-HP ink. Figure 1: Non-HP ink iconc00841629.jpg NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer service or repairs required as a result of printer failure or damage attributable to the use of non-HP ink will not be covered under warranty. If a hollow ink drop icon displays, the ink cartridge represented by that color icon has very little ink remaining and will need to be changed soon. You might be able to continue printing for a short period of time with ink remaining in the print head assembly. Replace the ink cartridge when the Replace Soon warning message displays on the color graphics display. Figure 2: Low ink level iconc00841630.jpg When the Empty Ink message appears on the color graphics display, the indicated ink cartridge is out of ink. Replace the indicated ink cartridge. Method two: Check ink levels from the Windows computer The estimated amount of ink remaining in the ink cartridges can be checked from the computer. See the on-screen HP Director Help for information on checking the ink levels from the Printer
  1. Open the printer Toolbox. To do so, do one of the following:
    • Open HP Solution Center, click the Settings menu, then point to Print Settings , then click Printer Toolbox .
    • Right-click the HP Digital Imaging Monitor in the tray, then point to your printer model name, and click Display Printer Toolbox .
    The Toolbox opens.
  2. Click the Estimated Ink Level tab. The estimated ink level gauges display.
Method three: Check ink levels from the Setup menu
  1. Press Setup on the printer control panel.
  2. Scroll down and select Display Ink Gauge . The Ink Gauge status from the Tools menu will only display on the color graphics display.
Let me know if you have any other questions. Please rate this solution. Thanks.

HP Officejet Pro L7650 Print head problem


The reason why the printer refuses to print if you get low on one or more colors is that the system runs off negative pressure through the ink lines to the print head. If you were able to continue printing with an empty cartridge you could get air in the respective ink line, disrupt the negative pressure, make it so that that color will no longer print, and require you to get the printer serviced to fix the problem. I own a Cartridge World ink refilling store and I feel this is a good machine (compared to some of the others out there). The only down side with this type of machine is the print heads expiring or getting clogged as you are experiencing. The reason the black is clogged and not the other colors is that the black ink is pigment based and the colors are dye based. The pigment based inks do tend to clog print heads over time. You can try to rehydrate the print head with warm distilled water. if you can't get it working to your satisfaction you can buy a new black/yellow print head for $72. With this type of printer you should print at least one black and white and one color document per week to keep the print heads fresh. If they sit too long without ink flowing through them then they can get clogged and print poorly. I hope this helps belay some of the resentment you hold towards your printer.

HP K850 cartridge problem


I had the same problem, all cartridges lights came on.
I did two things:

1st: I clean the print cartridges plugs with Q-tips, just to insure there wasn't any ink build on the plugs. If you look were the cartridges are, you will see four plugs one for each of the cartridges. Each plug has four contacts. They should be a bright metal color. If they dull in color, they have ink on them. Unplug the printer and pull all the cartridges out and gentlely wipe the the contacts with Q-tips. Re-stall all the cartridges.

Note: The cleaning did not solve my problem but its good maintenance since in was looking for a solution.

2nd: What work for me was I un-stall my printer totally. Turn off the printer then turn off the computer, had a cup of tea, rebooted the computer and re-install the HP cd disk and drivers, turn the printer back on. After I reinstall the software and put the printer back on my network, everything is working fine for the last two days. The lites are off and the HP toolbox is reading the ink cartridges status correctly. I believe that a virus change the printer drives.
