Have continued with WF-3010DW print trials with edible inks over the past 10 days using the Matte Coated paper settings and standard quality for print quality settings. Have left the printer for 5 days without printing and have not carried out any head cleans or maintenance cleaning cycles.
All prints of our Excel test sheet on all media (110gsm Matte Coated Paper, Icing Sheets and Standard Wafer Papers) absolutely perfect and the print nozzle test pattern is also perfect, with no unbroken lines. The only concern to date is that occasionally, on 2 occasions, the leading edge of the media being printed picks up some black ink. It is very slight, however it is worth commenting on. Am wondering if to much ink flow is present on the black.
We are using refillable cartridges without any sponge filled with Kopyform inks, in order to test out excessive ink flow, we are trying to aquire some empty unfilled compatible cartridge cases that do have a sponge inside them. Our thoughts are that using a sponged cartridge would slow down or better modulate the ink flow. If we can not get any we will use cleaned up empty compatible cartridges to confirm this theory.
So all tests to date have worked well and we have now given the printer over to production and it will be worked for a couple of weeks to see how we go. If it holds up as we believe that it will, it is then time to sell a quantity into the market and see how it all goes from there.
Della Craven from Della's Cup Cake Heaven will run the production trials and will be reporting findings on a daily basis.
