Question about HP Photosmart 7850 InkJet Printer

Open Question

How do you clean the print heads on an HP 7850? Printing is uneven and can barely see the ink. It is usually very simple to find where you do this on other printers but I can't find it on the HP. Thank you for your help.

SOURCE: quit printing black

did anyone ever solve this issue? We have the same printer and can't get the Dam thing to just acknowledge black ink only.. When any of the color cartridges are low the stupid printer won't allow us to proceed printing in black until we replace the cartridge that is low..$#@**&^*$#

SOURCE: black ink not coming through

I had the same problem. Ended up replacing the black/yellow "printhead" and that corrected the problem.

Why is my hp officejet 6110 printing everything green


You didn't use the HP printer cartridges? I know they are expensive. but the quality is worth it . I trust not a cheaper ink in a quality printer. You may need to check this HP url

When you get to Solution four: Use an automated tool to clean the printhead a helpful tip is to repeat the printhead cleaning up to 4 times .

Uneven printing


You need to clean the cartridges and the print head. Remove the cartridges and clean the nozzles with a damp cloth, let it dry for a few minutes and then insert them back and now try to print a few pages, it should take about 5 - 6 prints before printing properly.

Suddenly stopped printing in black though colour is OK.I've tried all the usual things!


the ink head is probably jammed with dry ink. wihen the head is jammed, a lot of ink will pool at the bottom right of the printer. clean that pool, and dab the black ink head with a damp paper towel, but do not rub. blow the ink head with a can of compressed air. run a nozzle cleaning, and nozzle check until the printer is printing better. the nozzle check prints out grid for each color. if the grid is complete the printer is fine. sometimes a few horizontal bars will be missing and cannot be cleaned.

Very slow printing - HP 5610 all in one


Very simple solution: The cartridges still have ink in them but printing is very slow. Remove the cartridges from the printer. Take a wet paper towel and wipe the print head on each one until the ink flows from each head. Usually it is the color cartridge because it is used less than the black one. Once ink is flowing again, reinsert the cartridges into the printer and your normal printing speed will return. This worked for me, no thanks to the "experts" or trouble shooting guides.

INK Color is off


Hello,

That's usually a sign of a cartridge that is running low on ink. Especially if it happens in the middle of the picture. Also, make sure that you have HP Premium Photo paper when printing photos. Also make sure that you click the properties button on the print dialog screen and choose the correct paper type. It will make a much better picture. You cn find more information on the types of paper on page 7 of the manual.

Hope this helps. Please remember to rate this information.

Thanks

Heads are clogged. Has it been sitting for an extended length of time? Ink will dry up in the heads and tubes. Alot of work to take apart and clean and may still not work. Try to get a service manual at justmanuals.com
