Checking and cleaning the print head | 29 4. After the pattern is printed, use at least a 10× magnification eye loupe to examine it. • If the pattern does not have any gaps, the print head is clean. • If any dots or segments are missing or deflected, as shown below, run a cleaning cycle as described in the next section. Then print another nozzle check pattern to make sure the nozzles are clean. Caution: Don't run a cleaning cycle while thick media is loaded in the printer. Running cleaning cycles You can run several types of cleaning cycles from the control panel (or from Epson LFP Remote Panel2): normal cleaning, heavy cleaning, and powerful cleaning. Note: Run the heavy and powerful cleaning cycles only if multiple normal cleaning cycles are not sufficient to clear the nozzles. The heavy and powerful cycles use a large quantity of ink and should only be used if necessary. Always follow the heavy or powerful cleaning cycles with a normal cleaning cycle. For details on running a powerful cleaning, see the online User's Guide. The cartridges need to be at least 50% full to use a heavy cleaning. You may need to replace a low cartridge to run the cleaning cycle. After cleaning, you can reinsert the old cartridge. Caution: Don't run a cleaning cycle while thick media is loaded in the printer. 1. Print a nozzle check to make sure the print head needs cleaning, as described on page 26. 2.
