White Spots Appear

A possible cause may be that appropriate paper is not used or the amount remaining in toner cartridges is running low. Check the following.

Are you using paper that has absorbed moisture?

Replace with appropriate paper.

When performing 2-sided printing, do white spots appear?

Change the setting of <Improve Toner Fixing>. Changing the setting of this item may solve the problem. The improvement effect is stronger with <Mode 2> than with <Mode 1>.

NOTE

In the case of 2-sided printing with this item set, it may take longer until printing starts.

Are you using appropriate paper?

Check usable paper, and replace with appropriate paper.

Is the central area of high-density characters or lines left unprinted?

Change the setting of <Special Image Mode>. The improvement effect is stronger with <Level 2> than with <Level 1>.

NOTE

The stronger the improvement, the lower the print density.

Does uneven print density occur in a way that the print looks like a water drops pattern?

Setting <Rdc Waterdrop Pttrn.> to <On> may solve the problem.

NOTE

If you select <On>, print quality may be affected.

If the problem persists with <Rdc Waterdrop Pttrn.> specified, change the setting of <Sp. Transfer Mode>. Setting to <On> may solve the problem.

NOTE

If you select <On> and use the machine in an environment with high humidity, the print density may become lighter or uneven.
