6. Long time no work on printer.

Main problems:
·Printer have not been used for about one month, now it can't work as usual.
·Printer is not often used, three month later printer have problem on printing.
Settlement:
If long time no use on printer, it may cause following three cases:
·If external tank ink surface is lower than printer head, ink will flow back to the tank stronger than to the ink cartridges, so air bubble will resulted at ink cartridges, when printing, you will find line missing.
·When printer head at original right side, if rubber seal can't well cover printer head, the air will come in and damage printer head, ink will be dry or oxygen.
·If put printer in the environment of high temperature, dry circumstances, or under direct sunshine, this will result the ink in the wire or printer head to be volatilization, dry or oxygen.
Following measures will settle above problems, please do accordingly:
·If you will not use printer for long time, please print test sheet, you'd better print about 10 pages of four color or six color block, and be sure test result is good.
·Do print cleaning step, when cartridge holder at original right side, pull out power wire, move cartridge holder to left side by hand, use wet mop to clean the rubber seal(at right side of printer) carefully, then move back cartridge holder to the right side by hand.
