Color Laserjet HP4600: 51.2 k

No change in system, but the error 51.2 k now only message frequency starting.  I tried cold reboot, the problem persists.

The engine to the black was scanner/laser unit become seized.  It has been the case in everyone I met over the years.  Not an easy task to set for yourself to access the units/scanner laser from the rear. If you want to try to fix it yourself, you will need to do a google search for the service manual.  Once you remove the black/scanner laser (upper unit) you detach the spring of the shutter Assembly and remove I think that only 1 screw on the top and slide top metal on the side and off.  At the rear of the unit is the engine that is a chrome engine mounted on a printed circuit board of color.  Remove the 4 screws that fix the engine to the case and then remove the small clip that contains the part of the rotation down and gently remove the part of the spinning.  Clean the shaft of the part of spinning and then put a tiny drop of oil synthetic in the well, when the spinning part goes.  Put it back together and spin the engine a couple of times and then put in the Assembly, put the Assembly in the printer and it should work.  To confirm that you have a problem with the engine try to turn the tree before doing anything.  It will be very tight.  After you do what I told you above the motor must rotate freely.  Good luck.

  • HP Color Laserjet: HP Color LaserJet - lines/stripes

    Hello

    I have a HP color LaserJet and I get a lot of lines and streaks on my printed pages.

    I also note toner inside the printer and my printer seems to take cleaning cycles more than before.

    Thank you!

    Although I work for HP, my posts are MY opinion and not those of HP.

    I would recommend some of the things

    First of all, make sure that your firmware is up-to-date, go to the page software and drivers on HP.com download and install the latest firmware available for the printer.

    Then, make sure that the toner collection unit is not complete

    Finally, print a cleaning of the control panel of the printer page, normally, you should select the following text in the menu:

    • Maintenance of the unit
    • Calibration / cleaning
    • Cleaning page

The results are the same with a source - installation apparently progresses up to connect it the indicator product of progression from screen reached 99%, how it gives an error message "a Setup operation took too long to run. It is a fatal error, preventing the use of the product. Restart your computer and run this installer again. If the problem persists, please visit the web site of product support for your product. "It takes about 20 minutes for the phase of installation to go from 0 to 99%, and then later hooked up to 99% for 2-5 minutes, the error message is displayed.

    2. right click on the printer and select "Update Driver software"

    3. click on "Browse my computer for driver software".

    4. choose "Let Me pick one...» »

    5. Select the named driver: HP Color LaserJet MFP M477 PCL-6 Pro (make sure it's one with a dash between the pcl and 6!)

  • Color Laserjet 2550 L and XP SP3

    Hello

    I installed XP SP3, last week and since I was not able to print from my color laserjet 2550 L printer. I tried the windows troubleshooting printing suggestions for the use of different drivers, but no luck. Any body out there got any advice, it's a pain not being able to print.

    Thank you very much

    If there is no Purifier not listed on the Web site nothing listed in your programs menu or add remove software window, then all you have is a base driver installation.  Following the steps listed for remove driver and the entrance to the server properties should be sufficient.  Manual uninstallation is for printers that have utility programs or use Software Solutions of Support or Director.  Even still, following the instructions provided here should at least bring basic functionality.

  • HP Color LaserJet Pro M177 MFP: HP Color LaserJet not able to connect to connected HP

    Hello

    I try to activate my printer (HP Color LaserJet M177fw MFP Pro) ePrint and much more, but I'm not able to do it cause connection problem, I guess.

    When I'm trying to 'print the information sheet', for example, the printer is not able to connect (stay on 'Sign in' loop indefinitely).

    My printer is less than a Vodafone EasyBox router, with firewall disabled and no specific barriers defined by me.

    Should I set some port forwarding (even if they should apply to ignore the firewall, when turned on) or any other specific configuration in the router?

    the same connection problem, of course, it happens when I do touch printer and console web administration, of course.

    In addition, I'll let you know that my router is not blocking access, for example, to-from the web (i.e. I am able to manage my NAS from the outside, since he admitted to a DDNS) and other local devices

    I alreay set 8.8.8.8 and 8.8.4.4 as DNS pri/sec and had an output of cycle after the series of DNS.

    My printer also has a static IP address (defined by the DHCP protocol, based on the MAC address), so not a problem, I think.

    Thanks in advance for your help,

    Lorenzo

    Hi Lorenzo,.

    To enable Web Services fumctionality, you'll need to install the latest firmware on your printer (version 20160525)

    You can locate the current version of your printer by selecting configuration > reports > Page of Configuration, the firmware version is listed under the information section on the printer.

    Updated the firmware on Linux by following these steps, but I don't know if the latest firmware is available for Linux or not, try:

    Go to configuration, network configuration, network, IPv6 Services and turn it off.

    This DNS works better for Laserjet printers. Please change the settings to see if this will help the printer built-in Web server.

    Preferred DNS address: 209.244.0.3
    Auxiliary DNS address: 209.244.0.4

    Power cycle the printer.

      This indicates that the printer can indeed resolve the addresses. Newspapers also Awakenings that the printer communicates with the servers (connection is established and data transferred) via https (probably the web service), but always after a few minutes the clearance process is to expire.

    Hi @pisca46,

    Thank you for joining the HP Forums!

    I understand that there is no drivers for your HP Color LaserJet Pro MFP M277dw on Mac OS X 10.12 Sierra. I am pleased to see that for you!

    You are right that there are currently no drivers available at this time. In the meantime, I suggest trying the rest of this guide, of install a printer Mac driver by using Apple Software Updateand then try using the Apple Image Capture.

    Otherwise, all we can do is wait for the drivers and software provision, or plan to use an older version of Mac OS X.

  • MFP M277 dw: Color LaserJet MFP M277dw Pro issues with iMac

    I have a 2015 21.5 "iMac running El Capitan (10.11.3) and a HP Color LaserJet Pro M277dw MFP that falls in offline mode when it is idle for a while.

    Once the Mac has been sleeping, I can no longer copy, scan or fax without having to restart the printer and the iMac. And it is intermittent. This does not happen everytime the iMac goes to sleep, but no doubt it happens once or twice a week.

    The printer is connected both wireless (so that I can print from my iPad in other parts of the House.) and directly to the iMac via USB.

    I have updated all the HP software related and have applied the last update of the HP firmware for the printer as well. I also ran through all the game instructions that were provided with the printer.

    Other troubleshooting tips would be greatly appreciated.

    Hi @RBurgett,

    Thanks for joining the Forums of HP Support for a solution to your fall issue offline printer.

    I understand you have a HP Color LaserJet Pro MFP M277dw connected to a wireless network for your iPad and connected with a USB to your iMac running Mac OS X 10.11.3 El Capitan, but the drops of the printer is offline after has been idle for a while and becomes also insensitive after mode "Eve". I would like to help with that.

    If you see the message on the printer offline on the iMac, it would be because the iMac think he's using the wireless printer, when it should be using the USB connection.

    You should be able to solve that by unplugging the USB cable. Once the USB cable is removed, reset the Mac printing system. If you don't know how to reset the Mac printing system, here is a document of support that can help - reset the printing system.

    After printing Mac system has been reset, you should be able to reconnect the USB cable and add it to printers and Scanners.

    As far as being not able to copy, scan or fax without having to restart the printer and the iMac that could be solved by resetting the printing system and making sure the USB printer is listed in the printers and Scanner. When the printer seem to be insensitive, the first step is to perform a reset of the power on the printer.

    Please let me know if that solves the problem, or if you need assistance.
