Cleaning the print head
If you find that the printed data is unexpectedly faint or dots in 
the printed data are missing, you may be able to solve these 
problems by using the Head Cleaning utility to clean the print 
head, which ensures that the nozzles are delivering ink properly.
To use the Head Cleaning utility, follow the steps below.
Note:
❏Do not start the Head Cleaning utility while printing is in progress; 
otherwise, your printout may be marred.
❏To save ink, use the Nozzle Check utility first to confirm that the 
print head needs to be cleaned. This is because the cleaning process 
consumes some ink.
❏When one check ink out light is flashing or on, you cannot clean the 
print head. Replace the appropriate ink cartridge first. See 
“Replacing Ink Cartridges” on page 289.
1. Make sure the printer is turned on and all ink check lights are 
off.
2. Click Head Cleaning.
3. Follow the on-screen instructions.
4. Click Print Nozzle Check Pattern in the Head Cleaning 
dialog to confirm that the head is cleaned and to reset the 
cleaning cycle.
If you still find missing dots after cleaning, try these solutions.
❏Select PWR CLEANING from the control panel on the printer. See 
“PWR CLEANING” on page 238.
❏Repeat this procedure four or five times, turn the printer off 
and leave it alone overnight, and then try head cleaning again.
 
						

							212Printing with Mac OS X ❏Replace some of ink cartridges as they may be old or 
damaged.
If the print quality remains a problem after you have tried these 
solutions, contact your dealer. See “Contacting Customer 
Support” on page 349.
Aligning the print head
If you find misaligned lines or black or white banding on the 
printed data, you may be able to solve these problems by using 
the Print Head Alignment utility to align the print head. 
To use the Print Head Alignment utility, follow the steps below.
1. Make sure paper is loaded in the printer.
2. Click Print Head Alignment.
3. Follow the on-screen instructions.
Starting EPSON LFP Remote Panel
