Check paper and the printing environment
Step one: Use paper that meets HP specifications
Some print-quality problems arise from using paper that does not meet HP specifications.
●
Always use a paper type and weight that this product supports.
●
Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles,
voids, staples, and curled or bent edges.
●
Use paper that has not been previously printed on.
●
Use paper that does not contain metallic material, such as glitter.
●
Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in
Inkjet printers.
●
Use paper that is not too rough. Using smoother paper generally results in better print quality.
