● The printer driver setting or paper tray setting might be incorrect. Be sure that you have configured
the paper tray at the product control panel and have also selected the correct driver setting for the
paper that you are using.
● The print mode might be set incorrectly, or the paper might not meet recommended specifications.
● The transparencies you are using are not designed for proper toner adhesion. Use only
transparencies designed for HP Color LaserJet products.
