Epson PRO 3800 Guida Informativa

You can run a power cleaning cycle from the control panel if the normal 
cleaning process is not sufficient to clear the nozzles. However, the power 
cycle uses a large quantity of ink, so it is recommended only as a last resort. 

The cartridges need to be at least 50% full to use power cleaning. You may 
need to replace a low cartridge to run the cleaning cycle. After cleaning, you 
can reinsert the old cartridge.

 is highlighted, then press r.

, then press r. 

6. Press the

 

Enter button to start the power cleaning.

7. When cleaning is finished and the P

 

Power light stops flashing, print 

the nozzle check again to confirm that the head is clean.

For effective cleaning, always run a nozzle check between cycles. 

If the pattern is still missing segments after a few power cleaning cycles, turn 
off the printer and let it sit overnight. Then clean the print head again the 
following morning with regular cleaning cycles. If you still see no 
improvement, contact Epson for assistance. 

Caution: Don’t run a 
power cleaning cycle 
while thick media is 
loaded in the printer.
