Epson FA040XX Printhead Multimeter Test Sheet (Download)

This downloadable diagnostic test sheet provides the complete pin reference values required to accurately test Epson FA040XX printheads using a multimeter. It is an essential tool for technicians and advanced users to determine whether a printhead is electrically healthy or damaged before installation, helping prevent costly mainboard failures.

Compatible Printheads

This test sheet supports the Epson FA040XX printhead family, including FA04000, FA04010, FA04040, and other FA040XX variants.

About FA040XX Printheads

The FA040XX printhead is widely used in entry-level Epson EcoTank and Expression printers manufactured roughly between 2013 and 2022. These printheads typically feature four ink ports, a small oval mesh intake filter, and are designed for 4-color CMYK printers. They are commonly found in refillable tank printers and entry-level home printers worldwide.

Printers Commonly Using FA040XX Printheads

Epson EcoTank L-Series

Examples include L110, L120, L130, L210, L220, L300, L301, L310, L350, L351, L355, L360, L362, L365, L380, L381, L385, L405, L455, L485, L550, L555, L565, L605, L655, L3110, L3150, L3210, L4150, L4160, and L5190. These are some of the most common refillable EcoTank printers worldwide using the FA040XX printhead platform.

Epson Expression Home (XP Series)

Common models include XP-302, XP-303, XP-305, XP-306, XP-312, XP-313, XP-315, XP-322, XP-323, XP-402, XP-405, XP-406, XP-412, XP-413, XP-415, XP-420, and XP-423. These are typical entry-level home printers that share the same FA040XX printhead platform.

Epson WorkForce Models

Compatible printers include WF-2010, WF-2510, WF-2520, WF-2530, and WF-2540, which are small office printers that also use the FA040XX printhead family.

EcoTank ET-Series Using FA040XX

Many four-color EcoTank ET printers also use this printhead family. Examples include ET-2720, ET-2700, ET-2710, ET-2750, ET-2760, ET-2800, ET-2803, ET-2810, ET-2820, ET-2830, ET-2850, ET-2851, ET-2855, along with regional models such as ET-2400, ET-2450, ET-2600, ET-2650, ET-4700, ET-3710, and ET-3760.

Printers That Do NOT Use FA040XX

Higher-end EcoTank printers use different printhead families. Examples include ET-8550 (FA170 / FA190 series), ET-15000 (FA170 series), and ET-16500 (PrecisionCore printhead).

What’s Included

This download contains the complete pin-to-pin connection values, expected OL (open line) readings for every test point, and a detailed interpretation guide explaining how to evaluate the measurements.

If a data point displays OL but continuity is detected, the printhead is likely shorted or burned and installing it may damage the printer’s mainboard. If measured resistance deviates by more than about 20%, it may indicate degraded internal capacitors or a manufacturing defect that affects ink firing voltage and print quality.

Tools Required

To perform the test you will need the printhead (not included), a multimeter (not included), and this downloadable test sheet. An optional accessory is the ET-8550 Printhead Cable available here:

About the Test Data

The reference values in this sheet are derived from Epson’s internal factory calibration process used during manufacturing. Inside Epson facilities, each printhead’s electrical response is measured and encoded into a correction table known as the HEAD ID, allowing the printer to automatically adjust firing voltage and waveform parameters to compensate for small manufacturing variations.

By following this sheet together with the instructional video, users can learn how to take precise measurements, identify abnormal readings, and determine whether a printhead is within safe operating tolerance.
