All inkjet printers must be used at least once a month to keep them in good condition. I f u have nothing to print, then just run off a test page.
I am presuming you have not printed for a while, and if this is the case then your system is clogged with dry inks. If you are using a new ink cartridge, there is no need to soak it. You need to get some head cleaning fluid, available from any good pc shop, inject some into your old cartridge and run this through the printer until it cleans. with lexmark this can take hours of printing to clear.
