Printing problems
239 6. Troubleshooting
The wrong printer driver was selected. Check the application’s printer selection menu to ensure that your machine is selected.
The software application is malfunctioning. Try printing a job from another application.
The operating system is malfunctioning. Exit Windows and reboot the computer. Turn the machine off and back on again.
Pages print, but they are
blank. The toner cartridge is defective or out of toner. Redistribute the toner, if necessary.
If necessary, replace the toner cartridge.
• See "Redistributing toner" on page 60.
• See "Replacing the toner cartridge" on page 62.
The file may have blank pages. Check the file to ensure that it does not contain blank pages.
Some parts, such as the controller or the board,
may be defective. Contact a service representative.
The machine does not
print PDF files correctly.
Some parts of graphics,
text, or illustrations are
missing. Incompatibility between the PDF file and the
Acrobat products. Printing the PDF file as an image may enable the file to print. Turn on Print As Image
from the Acrobat printing options.
It will take longer to print when you print a PDF file as an image.
The print quality of
photos is not good.
Images are not clear. The resolution of the photo is very low. Reduce the photo size. If you increase the photo size in the software application, the
resolution will be reduced.
Before printing, the
machine emits vapor near
the output tray. Using damp/wet paper can cause vapor [white
smoke] during printing. This is not a problem. Just keep printing. If you are bothered by the smoke [vapor], then
replace the paper with fresh paper from an unopened ream.
