It’s come to our attention that there is a small issue with the cyan ink which has the batch numbers 717D0A2C / 718F0C21 / 719BDD00 The symptoms are over spraying and eventual nozzle drop out. This will occur because of the viscosity of the ink and the nozzles are not strong enough to fire through the heavier ink. During the hot spell a shipment was left in extreme temperature in a vehicle which activated the curing prematurely. There is zero risk of damage to the machine or printheads but as per usual we will stand over our warranty and will take care of all issues. If you have a bag of cyan with the batch number ending in 0C21, OA2C, DD00 please check your nozzle test and physically feel the ink bag for hard lumps and we will send a new one out for you. Those of you that have been using OEM ink for years before switching to us are probably well used getting ink alerts and unfortunately we are no different, however this is the first time in 5 years. Simply fit to the machine and perform a short flush procedure, in some cases this may take 3 short flush procedures. If in doubt always call us for assistance. Short flush procedure: please go to your tools, setting tab at the bottom and choose short flush, follow on screen instructions. Many apologies again and please feel free to call for any assistance.
