Question about OKI C Office Equipment & Supplies
This is a new printer and has been installed as per the install doc; however when we print documents the text appears ok, but the images are blurred.
It sounds like this is an HP driver issue. HP drivers have built-in "optimizations" (that unfortunately have bugs) for things like printing photos. Different programs (word, for example) try to take advantage of these optimizations in different ways. When they work, they give superior photo printing (faster, with more accurate color). When they don't, you get black squares. This is why "converting" it to PDF worked for you -- Word printed it through the PDF driver instead of the HP printer driver, then when you printed the PDF file, that program avoided those optimizations when it sent the images to the printer. Unfortunately, the translation caused quality loss. If your goal was to print out something like a "proof-sheet" of photos, you might try the free photo organizer at www.preclick.com. It will print these for you, captions and everything, and should be able to avoid the driver issues.

try to heat up the printhead of the cartridge on hot water about 90degre celsius and clean the head whit a clean soft paper (toilet paper is great and cheap) and make a clean nozle on the printer software.

I have OS-X 10.4.11 and had the same issue; any printing just spat out blank pages.
I installed the following driver which completely resolved the issue:
There's a similar one for 10.5 that I haven't tested, to be found here:
If you use 10.5 and this driver works for you, please let others know by posting here, too.

1. First, try turning printer off and on.
2. Next, on the computer side, this is how you manually clear the printer queue.
1. Go to Start, Control Panel and Administrative Tools. Double click on Services icon.
2. Scroll down to the Print Spooler service and right click on itand select Stop. In order to do this, you need to be logged in asAdministrator. At this point, no one will be able to print anything onany of the printers that are being hosted on this server.
3. Next you need to go to the following directory: C:WINDOWSSystem32spoolPRINTERS.Delete all the files in this folder. This will clear all print queues(it’s a good idea to first make sure there are no other print jobsbeing processed on any of the other printers on the server becausedoing this step will delete those jobs also)
4. Now you can go back to the Services console and right-click and choose Start for the Print Spooler service!
You can also go to a command prompt and type net stop spooler or net start spooler to start and stop the service.
I hope this helps. If you have more questions, let me know.

Seem like blocked hole(s) on the color print head...
Most likely if there is a deep clean option then do it (may need a few times to unblock a hole or never).
Also get the printer physically cleaned up if you can see dusts inside (vrtical lines on color bars).
