If Cover A is open, you cannot rotate the toner carousel.

Rotate the toner carousel to locate the relevant developer roller(s).
Push or pull on a toner cartridge to rotate the toner carousel forwards or backwards.
Touch only the plastic toner cartridges. Do NOT touch the developer rollers or print quality may be impaired.
If the carousel will not turn, check that Cover A is closed.

Figure 7. Example: the yellow (Y) developer roller.
Check each of the four developer rollers.
Each developer roller should have a uniform coating of toner (see Figure 7 above for an example), with a darker horizontal line along the centre. It is normal to find that the colour of the roller is darker than expected.
Check that the toner cartridges are installed in the correct slots.
Each toner cartridge must be installed beneath the developer of the same colour (see Figure 7 and Figure 9).
The developer rollers must be coated in the correct colour. If the colour is incorrect, the developer is contaminated.
Vertical score marks or thin gaps indicate a damaged developer.
Figure 8. Example of a damaged developer roller (black).
Figure 9. Example of a damaged developer roller (cyan).
Figure 8 and Figure 9 show developer problems that would cause small vertical gaps to appear in solid sections of black or cyan respectively.
Gaps, patches or darker areas wider than these examples indicate that the toner has not coated the developer properly.
If one or more developer rollers appear to be damaged, then the printer may require a service. Contact Epson for further advice.
Reinstall the photoconductor unit, and close all the covers.
If the developers appear to be contaminated, and the toner cartridges are installed in the correct slots, contact Epson for further advice.
The developer rollers in the AcuLaser C1100/N, CX11N/F and CX21N/F are not user-replaceable, and should be fitted by an Epson-trained service engineer.
Using non-genuine toner cartridges may affect the developing process, and contaminate the developers.
Epson recommend replacing non-genuine toner cartridges with genuine Epson ones. However, if the developers are badly contaminated, and the colours do not improve over time, the developers may need to be replaced as well.
