Printouts Are Faded

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 appropriate paper?

Check usable paper, and replace with appropriate paper. Also, specify the paper size and type settings properly.

Are you using paper containing much paper dust? (LBP664Cx)

Using paper containing much paper dust may result in a faded or streaky printout. Setting <Corr. Img. Corrup. by Ppr. Dust>/<Correct Image Corrupted by Paper Dust> to <On> may solve the problem.

NOTE

If you set to <On>, the printing speed may be slower.

Is the print faded or uneven in density depending on the paper type or the environmental conditions?

Change the setting for <Reduce Toner Flaking>. Changing the mode setting may solve the problem.

NOTE

LBP664Cx

The improvement effect is stronger with <Mode 2> than <Mode 1>. First try with <Mode 1>.

Setting a greater improvement effect may result in curled printouts or slower printing speed.

LBP623Cdw / LBP621Cw

If you set to <On>, ghost images may appear in blank areas.

Are you using the machine in an environment with high humidity? (LBP664Cx)

Setting <Reduce Toner Fixing Stain 2> to <Mode 2> may solve the problem.

NOTE

If you set to <Mode 2>, printouts may be curled.

Is the machine installed in an environment where the temperature changes rapidly and drastically?

When the temperature changes rapidly in the environment where the machine is installed, condensation occurs, which may cause fading or bleeding in images and text. If <Control Condensation> is set to <On>, condensation inside the machine will be removed. Condensation removal may be performed automatically due to temperature change.

IMPORTANT

While condensation removal is being performed, printing may not be performed properly and blank paper may be output.

If you set to <On>, you need to keep the machine turned ON to maintain the effect of condensation removal.

If you set to <On>, the setting of Auto Shutdown is disabled.

Is the amount remaining in toner cartridge running low?

Check how much the amount remaining in toner cartridges is left, and replace the toner cartridges as necessary.

Regardless of the displayed toner level, the toner cartridge may have reached the end of its lifetime due to the machine's environmental conditions and the deteriorated materials in the cartridge. Replace the toner cartridge.

Are printouts faded immediately after toner cartridge replacement?

Printouts may be faded immediately after replacement of toner cartridges with new ones. In this case, setting <Rdc. Faint Print After Rplc. Cart.>/<Reduce Faint Print After Replacing Cart.> to <On> may solve the problem.

NOTE

If you set to <On>, the setting will become effective with next replacement of toner cartridges.

Immediately after cartridge replacement, a certain amount of time is required for toner to be evenly distributed inside the cartridge.
