That is quite normal . All inkjets run a cleaning cycle when turned on to make sure there is a good flow through the printhead and to prevent the head from becoming blocked. You cannot turn it off.

    I have the same problem, but even worse : he cleans his printheads every 2 to 6 printed pages !!! It has become absolutely impossible to keep on working with this printer ! There must be something wrong ! Who can help ?

    This has got to be the dumbest "innovation" that HP has ever devised! Our 8500 decides to "clean the printheads" right in the middle of "time sensitive printing" when important clients cannot stand around and wait for a cleaning process to be over. Let me manually decide when to do this procedure and I'll gladly assume the resulting risk, as I have done in the past with all my previous HP printers. If this cannot be resolved, my loyalty to HP is over!

Hp officejet pro blank pages with full ink cartridges.


Try reinstalling all of the printer software. If that does not do it then something is wrong with the printhead itself, specifically the area that controls the flow and metering of the black ink.

I have a continious inking system and ink streak. we took it apart and cleaned the ink ports and the ink runs through the tubing firn


Hi

This is not the problem with the ink supply through the tubing. But your printheads need to be cleaned hence using the HP software which is installed in your system try to clean it and it will solve much of the problem you are facing if not then you have to replace the heads.

after you cleaning those toners put them all back to the printer. click here to view the video clip on how to put back the printhead. click here to view the video clip on how to put back the inks. close the cover. (the cartridge access door) when your done doing it, proceed to the next step.

*Clean the toners using the control pannel of the printer -press the Setup (wrench icon) button -keep on pressing the right arrow key then, look for the "tools menu" -under tools menu look for "clean printhead" -after your done cleaning it and its ask for level 2 cleaning process, please do so. -after cleaning press the setup again, look for tools, then look for align printer. -after aligning it, you should be getting the message "Alignment Successful"

How do I clean the printhead or do I need to clean the printhead


Only clean the print head when you are have ink issues. And you do so with a cotton swab and alcohol on the gold etchings on the print head only.
