Occasionally Epson printers may develop minor blockages to the print heads. A head
blockage is identifiable by performing a nozzle check. Once printed examine the nozzle
check pattern and identify and missing or misaligned lines as pictured below.

Missing lines can be caused by an air pocket or a blocked print head.

To identify the cause perform a head cleaning cycle followed by a further nozzle check. Compare the two nozzle check patterns. If the nozzle gaps have changed position then the issue is most likely caused by an air-forge or air pocket in the cartridge. If the gaps remain constant then the issue is possibly due to a blocked print head. Print head blockages can be caused by a variety of different issues. The most common cause is dried ink inside the head.

If the issue appears to be a blocked print head you will need to clean the print head.

Full Instructions provided with purchase. Please note with Large Format Printers you will need a cartridge to use the cleaning fluid.
