E-Tech WT7900 User Manual

•

Cover the printer with a non-static cloth. This helps protect it from 
dust, which can interfere with the print head nozzles.

Before returning the printer to use, follow these steps:

1. Turn on the printer and shake the white ink cartridge (see page 79).

2. Run a nozzle check and select the 

PRINT WITH WHITE INK

 option 

(see page 83).

Check the results and clean the print head, if necessary (see page 84).

3. If the printer hasn’t been used for more than a year, you may need to 

refresh the white ink supply (see page 86).

4. You may also need to realign the print head (page 87) to ensure good 

print quality.
