4. Make sure the paper or media type setting is appropriate for the fuser temperature.NOTE:Unlike ink printers, laser printers use heat to fuse a plastic toner to the surface of the paper. Make sure to use heat-resistant paper, and labels and envelopes that use adhesives compatible with the heat and pressure of the product's fusing process.
   1. If you are experiencing any issues in the following list, adjust the setting.

Maybe you need to clean the drum, blades or the developer roller. Maybe the problem is in the toner you use.

Try the setting for glossy photo media. You want a minimum of ink. Also use the transparency media intended for ink jet AND observe the correct side to be printed on.

Right click on the printer icon. Click Properties. Click Preferences.
Click Paper/Quality.
Find where it says Type is. Select transparencies from the pull down menu.

The printer has no ability to know the paper type, this setting happens in SOFTWARE, like Word. Then the command is sent to the printer, more commonly you would change papertype for photo printing....Look in the software, and not the printer itself.

I possess a digital copy of this manual. If you are interested, I can be reached at [email protected]. Please make sure to include the "HP K80xi" manual in your heading. Hope this works for you.

Use this item to configures the fuser mode associated
with each media type.
Change the fuser mode only if you are experiencing
problems printing on certain types of media. After you
select a type of paper, you can select a fuser mode
that is available for that type. The available selections
might include some or all of the following modes:
NORMAL: Used for most types of paper.
HIGH 1: Used for rough paper.
LOW: Used for transparencies.
HIGH 2: Used for paper that has a special or rough
finish.
The default fuser mode is NORMAL for all print media
types except transparencies (LOW), and rough paper
(HIGH 1).
CAUTION
Do not change the fuser mode for transparencies.
Failure to use the LOW setting while printing
transparencies can result in permanent damage to
the printer and fuser. Always select Transparencies
as the Type in the printer driver and set the tray type
at the printer control panel to TRANSPARENCY.
When selected, RESTORE MODES resets the fuser mode
for each media type back to its default setting.
Hope this helps

Hello,

Nice printer.. Hope this will give hints. Considering transparency papers, please try another batch of or a piece of transparency paper. Try to adjust also the graphics preferences (dark to light) aside from transparency paper selection. Have a nice day.

Best regards,
