What does a printhead look like? I have a HP Deskjet 540 and I was told that it needs a new printhead.?

HP Deskjet printers printheads are part of the ink cartridges and the placement area.  I would suggest first to replace your ink cartridges and clean the print heads.  If this does not fix the problem, then the less expensive fix is to get a new printer.

There is a cleaning utility on every HP printer.\nThis is how you find it.\n1.  Pretend you are going to print something.  \n2.  When the "PRINT" window appears instead of just printing \n    select the properties tab.  This will be next to your \n    printer name.\n3.  This will bring up the "Print Properties"  window.   \n    there should be tabs along the top, the last of which \n    being service.  Select that.\n4.  Click on the series device box.\n5.  This will being up one final page.   Click clean the \n    clean the cartridge.\n\nYou may have to so this repeatedly in order to bring the print quality back.

Hello. I recently purchased an HP 3600n Color Laser* from Office Depot to replace 2 of my three printers. To date I am very happy with the results. It did not completely replace my HP G85, since it is also my primary fax machine. It did however replace my Lexmark 4039 10Plus and all primary color printing. It still leaves me with an OkiData 390 to print labels. I use the 5000 box of continious feed labels, so at the moment there is nothing I can do about replacing it. Between my two companies, the wifes eBay and the three kids printing daily, we print a case of paper a month (5000 sheets).\nI would have loved to have purchased an all-in-one color laser but all things consided I am very happy.\nOne thing that swayed me to the HP, in that price range, was it came with a print server built in.\n\nI hope this helpped.

Unfortunately with any printer not just epson if you don't use them the print head will dry out.  If it has been more than about 6 months since you have successfully printed with the Epson, call it a door stop.\n\nIf not try running many many print head cleaning (maybe 20+).  Your manual will tell you how do to this.  You should hopefully see some improvement.  If not then it will need to be professionally cleaned or serviced.\n\nMake sure you read your manual so that you are doing the proper maintenance to make sure your printer works in the future.

Well, talk about annoying, and expensive, too. Yes on consulting with Hewlett Packard about how to fix. The guy at Staples told me to shut the printer off when I am not using it. He said the heat inside the printer can sometimes do a number on the ink cartridge, so I have been shutting the printer (an old 1994 HP 520 Deskjet) off when not cranking out earthshaking documents and lo and behold, the ink does seem to last longer. I have a hunch, however, your issue is different. Be sure to get in touch with Hewlett Packard and get them to give you a crystal clear answer that makes sense to you. It's to their advantage they help you enjoy their own product. Also, have a good summer, by balancing the frustration of printer problems with time spent outside running around and having fun, generally. I am wishing you the best summer yet!

It sounds as if you might not have the right driver installed for your printer.\n\nMake sure you have the proper driver installed by deleting the printer from your system and re-adding it. You may also want to check with the printer manufacturer to make sure you have the most recent driver.\n\nHope this helps.

thereis dry ink in print heads of your printer, i guarantee thats the problem (that is assuming your printer is ok, and you have installed cartridge correctly).\n\nclick Start -> Settings -> Control Panel -> Printers (and Faxes). right click on the icon with your printer name. click properties. look for a tab that say "tools" or "utilities" or "service" or something similar. there usially in a "clean print heads" (or something with the same meaning) button in it. insert paper into your printer and click that button. you might have to try in a couple of times.\n\nthe only other problems i can think of that would produce this result would be (1) cartridge is not instaled correctly (2) there's something wrong with the printer (3) bad cartridge. in this order of probabilty.\n\ngood luck

Assuming you are talking about the OfficeJet 700, http://h10025.www1.hp.com/ewfrf/wc/product?product=58709&lc=en&cc=us&dlc=en&lang=en&cc=us\n\nYou need more information.  Desk Jet 700 does not come up as a product in HP Support.

Hi,\n\nI found a firmware for your printer at HP.com\nIt says that it fixes ""Memory Full" - When loading more than one document in the automatic document feeder (ADF) to make copies, the all-in-one may display "Memory Full; Press Enter"\n\nAnd it fixes lots of other issues with this printer.

if you soak a cartridge in water, you will end up with a soggy cartridge.  don't do it.\n\nhowever, you can try to tap the printhead ON top of a small amout of warm distilled water it may break up the ink that has gathered on top of the printhead.\n\nyou may leave the cartridge sit on top of a damp paper towel for a while, but make sure the entire printhead is touching the dampness of the paper towel to avoid it drying out further.\n\none other thing you can try is to hold the printhead over top of steam (like out of a tea kettle) for a few seconds until you see the ink begin to flow.  be very careful when doing this, as you could very easily melt the printhead and it will definitely be ruined.  i only use this as a last resort.\n\ndell was started by HP, and they did nothing but cause hp problems, and most of their customers are not happy with the printers and are returning to HP.\n\nmy recommendation is to just buy a new cartridge and learn not to let it sit unused for so long.\n\ngood luck

Compatibility isn't the issue.  The problem is that you either use the printer infrequently or are using refilled or third party cartridges and your print head is dry.\n\nYou will need to run several print head cleanings to see if you can remedy this.\n\nOn a brother you have a button that says "ink"  hit that and scroll through until you see an option that says clean print heads or clean nozzles.  Hit OK.\n\nHopefully after a couple print head cleaning you will see some improvement.  However if it has been quite sometime (more than a couple months) since you last printed successfully. Then it may be time for you to replace the whole darn printer.  Or have the print head serviced.

If you're using an ink-jet printer, it sounds like the print heads need cleaning.  You often get white lines when dirt or dry ink builds up.  You can use household items to clean, but it's probably best to buy cleaning cartridges.  See the links below for further information.\n\nhttp://www.e-inkjet.co.uk/cgi-bin/cleaning.asp\nhttp://www.cartridgesave.co.uk/info/inkjet-cleaning-cartridges.html

Hi friend, I'm not sure about the model but i think it is a multi-function printer that you have. \n\nFirst, If your computer can't print and scan. Check if there is power and check if the printer cable is properly attach at your CPU. \n\nSecond, check if you still have enough ink at ink level section. You may find that at Control Panel / Printer and Fax / right click printer the one you are using / printing preference.\n\nThird, Have you try to install a replacement ink or not original ink at your printer. It might ruin your printer if your using non-geniun ink cartridges.\n\nFourth, Go at maintenance.\n\nFifth, If still not work, go at the nearest EPSON service center in your area Or visit the website of EPSON and email them regarding your issue or concern. \n\nI hope you fix your printer very soon..good luck!

First, make sure all the cables and cords are secure and connected.\n\nNext, make sure you use the manufactures CD, if available, and install the latest device drivers for the printer (if you don't have the cd, visit http://hp.com and search for drivers).\n\nFinaly, restart your PC, and try to print again (making sure you selete the correct printer to print to).\n\nIf you are recieveing errors, or have futher problems and you have a new printer, you should be intitled to free toll-free support.

somehow your printers settings have possibly been knocked out of sync.\n\nIt is probable that uninstalling and reinstalling the HP software will reset everything.  You could always start by unplugging the printer from the wall and the computer, waiting a minute or so, and then plug things in, and try again.\n\nIf this doesn't work you could always then resort to uninstalling and reinstalling the drivers.\n\nThis is where I would start.  If things still fail, I would definitely get in touch with HP.  If this is a new purchase you should still have some type of warranty or support available to you.\n\nHope this helps and good luck.

Use the utility software for the printer to clean the print heads, it should help.

I have searched everything I could think of, but I haven't found a HP Color 9850mfp.  The specs are listed in the first link.  The second offers a used HP Color 9850mfp for sale -- no price listed.\n\nGood luck locating the printer you are looking for.
