Test matrix

What to test and what a pass actually tells you

Run the test closest to the symptom. A passing result narrows the diagnosis; it does not certify the entire device.

Printer Color Test PagePrint CMYK and RGB reference blocks to inspect missing colors and obvious print-quality problems.

A repeatable defect on a controlled reference is stronger evidence of a printer/driver path problem than a single bad document.

→
Printer Grayscale Test PagePrint a stepped grayscale to inspect tonal separation, color casts, and blocked shadows or highlights.

A repeatable defect on a controlled reference is stronger evidence of a printer/driver path problem than a single bad document.

→
Printer Alignment Test PagePrint fine lines and alignment references to inspect registration and obvious misalignment.

A repeatable defect on a controlled reference is stronger evidence of a printer/driver path problem than a single bad document.

→
Printer Small Text Test PagePrint small text at several sizes to inspect sharpness, edge quality, smearing, and readability.

A repeatable defect on a controlled reference is stronger evidence of a printer/driver path problem than a single bad document.

Browser Online Status TestCheck the browser online state, available connection hints, and a short round trip to DeviceOK.

A pass proves this browser can reach DeviceOK through the current network path; link negotiation and router counters require OS/router evidence.

These paths combine this model's documented limits with live evidence, instead of copying a generic troubleshooting checklist.

Epson ET-4800 shows offline over networkET-4800 supports both Wi-Fi and Ethernet. A powered printer that is offline in one network path should be isolated by checking its active connection, IP/network state and direct print behavior before reinstalling everything.

Evidence handoff

If the browser cannot reach the suspected subsystem

Keep the browser result as one observation, then move to the operating system or manufacturer diagnostic that can see the protected hardware state. Do not interpret an unsupported browser API as a failed component.
