When Not Using for a Long Period of Time
If the printer will not be used for a long time, turn its power off, disconnect the USB cable, and then unplug it from the wall outlet. It is recommended to print at least once a month, because the printer consumes a considerable amount of ink for periodic maintenance and print head cleaning when switched on after a long period of inactivity.
Be careful of the following:
The nozzles of the print heads may dry out and become clogged. To prevent this, periodically print something. Even if you do not print anything, turn the printer on for a few minutes once a month.
If you do not use the printer for a long period of time, always check if the nozzles are clogged by printing a nozzle check test pattern. Clean the print heads as necessary, and then begin printing.
If you try to use the printer after it has been out of use for a long time, it may not print properly even if head cleaning is carried out several times. If this is the case, carry out head flushing. If the print heads are still clogged, leave the printer for about ten minutes, and then print the nozzle check pattern. If the problem persists, switch the printer off and leave it for at least eight hours. This should unclog the print heads.
After head cleaning is performed multiple times, clogged ink will dissolve over time, and normal printing may become possible.
If there is no improvement after performing the steps above, contact sales or service representative.
