Epson WF-7710 Errors 031006 and 031008 After a Printhead Flush: Why It Prints Blank

Question:
Why did my Epson WF-7710 show errors 031006 and 031008 after a manual printhead flush, then start up but print blank pages despite head cleanings and nozzle checks?

The WF-7710 showing 031006 and 031008 after a manual printhead flush, followed by blank output, does not identify one failed part by itself. Moisture or ink on the printhead flat-flex cable (FFC) contacts is one possibility; a poor connection, damaged cable, printhead failure, or printhead-driver circuitry fault can also cause loss of printing. The printer turning on again does not confirm that the printhead circuit is safe.

Stop running head cleanings and nozzle checks for now, and unplug the printer before inspecting it. Repeated cleaning uses ink and can add strain without fixing an electrical or connection fault. If experienced with printer service, inspect accessible FFC ends for ink, moisture, corrosion, tears, or a cable that is not seated squarely. Do not reconnect or reseat a cable while powered. Allow suspected moisture to dry fully before restoring power, and do not scrape contacts or use liquid cleaners on the cable.

If there is visible contamination, damage, or uncertainty about safe access, do not continue disassembly. A damaged FFC or printhead can affect the mainboard, and replacing a printhead before checking the driver circuit may risk damaging the replacement. Do not bypass or replace a fuse as a guess; a fuse may open because of an unresolved short. Board-level testing may be needed to distinguish a cable/contact problem from a failed printhead or driver component.

If cables appear clean, dry, and properly seated but the nozzle check remains completely blank, professional diagnosis of the printhead and mainboard drive circuit is recommended. Avoid further powered cleaning attempts until the electrical cause is assessed.
