My printer is going so slow it takes several minutes to print one separate page. I have 3 of these printers for over a year and this is the first time I have had this problem. I swapped it out with one of the other printers and tried to print from a different computer and program but it didn't make a difference. Also prints slow in the copy mode.

Here is the link to all the support options for your printer including user manual and troubleshooting if you need it; http://h10025.www1.hp.com/ewfrf/wc/product?product=421991&lc=en&cc=uk&dlc=en&lang=en&cc=uk first follow this troubleshooting procedure if you have a windows pc connected; http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00093466&lc=en&cc=uk&dlc=en&product=421991&rule=36216&lang=en and this one for Mac; http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00108051&lc=en&cc=uk&dlc=en&product=421991&rule=36216&lang=en Hopefully this will resolve the issue, especially the third item about turning off the paper type sensor. any help you need with any of the procedures, please ask again. If this doesn't work, then; Make sure your drivers are up to date and not corrupted - download new drivers from; http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&cc=uk&dlc=en&product=421991&rule=36216&lang=en& see if you can borrow another printer from someone (doesn't have to be the same, but that would be best), install it and then see if you get the same problem, confirming if the data transfer from the pc is or is not the problem. If the other printer works fine, then the next thing to suspect would be the power supply - try plugging into a different power socket, and try and get hold of a new power adaptor and see if that works. Replace any connecting cables to the pc with new good ones, just in case that is the problem. Hope this helps, if the machine prints at all then it should be fixable :)

It is a cartridge problem. Solution for my hp 3645 (I have the same story as bb18, but different printer) was to remove color cartridge! 
The printer is fast now, of course it does not print in color :) (I`m waiting for a new color cartridge) Good luck,
Marcin

If this printer has the duplexor feature there is a plate just above the paper tray and the paper may be stuck in there. Pull out the paper tray and look for a sorta blue button on the top right side inside of the printer. Push that button and the duplexor tray will drop down and that is where the paper may be hiding.

This could be from the image you are printing. If you are printing from a computer or memory card, the dpi (dots per inch) may be higher than some.Standard printing is typically 400dpi, and you can change the settings on your computer or the printer directly. Memory cards and some photos from your computer may be 600dpi and will likely take much longer to print since there is more "color information" that it is trying to fill.
Let me know if this helps.
