Xpres Subli-Print Epson R1800: Bulk Feed (series 4) installation Instructions XP5043 - Manual (Page 6)

After the ink charge print out a nozzle check to see if all the colours are printing
correctly. If they are, you are set to go. If not, perform a head clean and test the
nozzle check again. You should see an improvement on the next nozzle check.
If still not perfect you can perform one or two more head cleans (
do not overdo
this exercise, and avoid the auto nozzle check ) until you get a good nozzle
check.
Occasionally a printer will stubbornly refuse to print a perfect nozzle check
after a couple of head cleans. There can be a number of reasons for this
including the fitting of a dye sublimation system for the first time or a printer
being left for a long time without running any prints.
One way of curing this is to force the printer into a ‘power clean’. To do this
you will need to send a good size image to the printer (use an 8” x 10” [20cm x
25cm]) and when about a quarter of the image has printed, press (and hold
down) the ink button on your printer (the one at the side of the power button).
After you have held this button down for 5 or more seconds the printer will
pause printing, perform a head clean and then carry on printing where it left off
(it is not necessary to waste transfer paper on this exercise).
You may have to hold this button down again 1-2 more times during the print –
you should be able to see if the banding is disappearing. If you have had to
press the button for the 3
rd
time the printer will now perform a ‘power clean’.
Print a nozzle check immediately after this. If this nozzle check is good, you are
set to go. If there are still problems with it leave the printer to settle for at least
half an hour before printing out another nozzle check.
If there has still been no improvement you can carry out this ‘power clean’
exercise one more time including the half an hour settling time afterwards.
