HP Pro MFP M177fw manual Inspect the toner cartridge for damage

Page 96

●If dots or streaks appear in only one of the groups, replace the toner cartridge that correlates with that group.

●If dots appear in more than one group, print a cleaning page. If this does not solve the problem, determine if the dots are always the same color; for example, if magenta dots appear in all five color bands. If the dots are all the same color, replace that toner cartridge.

●If streaks appear in multiple color bands, contact HP. A component other than the toner cartridge is probably causing the problem.

Inspect the toner cartridge for damage

1.Remove the toner cartridges from the product, and verify that the sealing tape has been removed.

2.Grasp both sides of the toner cartridge and distribute the toner by gently rocking the cartridge.

3.Check the memory chips for damage.

4.Examine the surface of the roller on the toner cartridges.

CAUTION: Do not touch the roller on the toner cartridges. Fingerprints on the roller can cause print- quality problems.

5.If you see any scratches, fingerprints, or other damage on the roller, replace the toner cartridge.

6.If the roller does not appear to be damaged, rock the toner cartridges gently several times and reinstall them. Print a few pages to see if the problem has resolved.

Check the paper and printing environment

Use paper that meets HP specifications

Use different paper if you are having any of the following problems:

●The printing is too light or seems faded in areas.

●Specks of toner are on the printed pages.

●Toner is smearing on the printed pages.

●Printed characters seem misformed.

●Printed pages are curled.

Always use a paper type and weight that this product supports. In addition, follow these guidelines when selecting paper:

●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 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.
