DeskJet 3520: How to replace the printhead for Deskjet 3520

After 5400 pages, I got the 0xc19a0042 error on my printer. I changed the ink without best result. But when I opened the printer and cartridge and printerhead support touch, I often can print a few prints before the error will appear again. It cannot be a permanent error. Anyone know what could be the problem?

I bought a new HP printhead, but can´t find instructions on HPs or internet pages. Should I unscrew the upper part?

I hope that someone has had the same problem and can help me with some advice.

Thanks for all tips. I have now resolved the issue. As I said before, I bought a HP printhead on ebay. I opened the printer and with the exception of the stop of the cover that was no problem. For deassamble the lid Cap I had to pop out with a screwdriver. I pulled the power and LCD. Then, it was easy to lift off the cover and the scanner and change the print head with all the electronics. I cleaned up all the old ink of the word of the printer and it was a lot of ink. After putting together again it worked again.

  • Does anyone know how to clean the printheads for epson SX100?

    I got an Epson SX100 which was resisted for some time, while the ink cartridges are a bit dry.  There are still a lot of ink but I want to clean the print heads or nozzles, but I can't make it work.

    Answering your question: Epson could.  Tried to contact the manufacturer of the product in question rather than the manufacturer of the operating system (one of many) you could connect this printer?  :-)

  • Replace the screen for one with a higher resolution on Satellite P850-12Z

    Hi all

    I read a lot on the internet about the replacement of the screen on computers laptop toshiba and also I saw a video on [how to replace the screen for a Toshiba Satellite P855 | http://www.youtube.com/watch?v=Ncz3ZaI2I-s].

    Is it possible to replace the screen for a Toshiba Satellite P850 12Z (original: 15.6"@1366x768) to another screen with a higher resolution (say: 15.6"@1920x1080 or 15.6"@1600x900)?

    I'm sure that the graphics card is able to function perfectly with this screen (nVidia GeForce GT630M 2048 MB dedicated) and also I read a lot on laptop screen replacement, and I know that this screen has a connector 40 pin and it is an LED Panel, so I won't have to worry about the ups.

    I found several screens (15.6"@1920x1080) who say they are compatible with Toshiba, but I wan't to make sure a higher resolution Panel replacement is possible.

    Thank you in advance.

    Hello

    Exchange of the display is not supported by Toshiba, so I don't think that someone here can help you with this.
    I assume that Toshiba offers multiple views for this model of laptop. Only seller is different but resolution 1366 x 768 is always the same as on the original laptop specification.

    You can try to contact the nearest Toshiba service provider and ask for help. If someone can help you with that service of Toshiba. They have access to the database of Toshiba and can possibly tell if another view is usable on your machine.

    All this is quite complicated.

  • How to replace the contents of the settings/passwords backup server / current browser bookmarks?

    Classic scenario: after the bookmark long manual organization Firefox Sync adds trash of its server to my laptop or tablet.

    Where can I find how to replace the content of the backup of the server by settings/passwords / current browser bookmarks? Stupid me, I put a new synchronization and lost this ability.

    It is not recommended to go back to the old version of Sync

    The old version is removed he'll stop being available soon, it takes getting used to using the new version.

    IIRC, it is actually possible to force synchronization of the old working with Fx29 & Fx30 using an old profile or preferences of piracy, but I don't think I should encourage users to try this, but it would be better than using an older version of Firefox which is really bad. In fact using an old outdated version of Firefox is so bad, that it is customary to recommend using a browser on alternative day of someone else instead.

    Firefox ESR is aimed at corporate users, definitely, at the moment, it will use the synchronization of the former. Who will update soon to use synchronization well again, and this time, I guess the synchronization of the former will probably totally frowned upon for example are not available at all.

    It is possible to use the feedback system to leave a short comment on Sync. I would recommend this making, but at least to make very many people of spirit comments that I doubt will have no effect.

    Thanks for these videos. It may be useful to replace the memory, but I think that the owners of the laptop should not open the case. This may void the warranty.
    Be careful about this.

  • How to replace the CD/DVD-Rom on Satellite Pro 2100

    Hello

    My laptop's dvd - rom drive is old and broken, now that I have here an other dvd - rom drive, but I don't know how to remove the old dvd - rom without removing all parts of my laptop. Is there some service manuals how to replace the dvd - rom drive?

    Hello

    I m not 100% sure on the CD/DVD drive replacement on this laptop, but I assume that the procedure is very similar to other portable players.
    For the most part the ODD is secured with the screw at the bottom of the unit.
    You will need to remove this screw to get out and to swap the drive.

    But be careful and don t there if you have no experience!
    Moreover, not all readers are compatible and supported in reason parameters master/slave/c-salt. If you n t know which drives are compatible you should ask the ASP in your country for advice!

  • Qosmio G50 - 10J: how to replace the optical disc drive (ODD)?

    Hello

    the optical drive of my Qosmio G 50 does not work properly, it reads only some movie-DVD, but unfortunately not videogameDVDs at all, so I can't install any games.
    The guarantee is also outdated. So I wanted to ask if it is possible to change the disk myself, if it is then how I had to do and if by the laptop would be in
    risk to get damaged?

    I would be very grateful for each tip and all the help guys can give me!

    Best regards
    a.z.

    Hello

    In various cases the ODD replacement is very delicate.

    If you wish, you can consult this forum category.
    Here you will find some videos how to replace the ODD on the different laptop models:
    http://forums.computers.Toshiba-Europe.com/Forums/Forum.jspa?forumid=115

    This is also a nice Youtube Channel which provides the instructions how to replace the ODD:
    http://www.YouTube.com/user/toshibaeuropesupport

    But the ODD laser lens may be dirty. In my case I could solve similar problem, cleaning the lens of the laser by using a cotton ball and alcohol tip.
    But make sure that this!
