Take all cartridges out while the plotter is on,then re-insert them one by one and watch the ready light flash after each insertion.If it doesn't flash that could mean 2 things,either the cartridge is bad or the contacts on the carriage are dirty or the entire carriage needs replacing.
I tell all of my dj-4XX customers to check the spittoon assembly(on the inside,right side)for ink buildup. If it looks clogged,you can temporarily scoop the ink that solidified out,but eventually it(spittoon)will need replacing.
Hope this helps
