      If the print head on your REA Printer Accessories isn't printing, there are several potential causes. It could be due to a clogged nozzle, which can be resolved by releasing print and flushing, or by removing the nozzle plate and cleaning the print head. A faulty print head cable could also be the issue; try disconnecting and reconnecting it, or exchanging components. If there's no signal from the controller, check the controller. In the case of a print head defect, service is required.

      An incomplete print image on your REA Printer Accessories may be due to several factors. It could be that the pressure is not sufficient, in which case, increase the pressure or replace the ink filter. If the ink hose is too long, causing a loss of pressure, install the ink supply unit closer to the print head or increase the pressure. Print head adjustment may also be the cause that requires service.

    Why is there no ink flow in my REA JET SK 7 Printer Accessories?

      Charlene WareAug 13, 2025
      If there's no ink flow in your REA Printer Accessories, start by checking if there's ink in the tank and refill if necessary. If the ink filter is clogged, especially in a standard ink supply, replace it. Also, inspect the ink hose for clogs and replace it if needed. Ensure the quick ink disconnect on the ink hose is permeable; check the connector and replace if necessary. Lastly, if the ink viscosity is too high, replace the ink.
