Question:
Do you have instructions showing how to remove the EPS-135 power supply from an Epson L1800, Epson 1390, or Epson Artisan 1430 without breaking anything?
Answer:
Thank you for contacting BCH Technologies, and please accept our apologies that we could not answer sooner. We know printer problems are often urgent, but we want to give each question careful thought and provide a detailed answer. Thank you as well for supporting BCH Technologies and the BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies].
The linked video covers testing the EPS-135 power supply used in the listed Epson L1800, Epson 1390, and Epson Artisan 1430 families. Removal details can vary with printer revision and region, so verify the exact model and the label on the installed power supply before following any disassembly sequence.
Unplug the printer from the wall and disconnect USB and other cables before opening the case. Allow time for stored charge to dissipate. A power-supply board can retain hazardous voltage after the printer is unplugged, so do not touch capacitor leads, the AC-input area, or exposed solder joints. Never perform live voltage testing unless you are trained and equipped for mains-powered electronics.
Before removing covers, photograph the printer from several angles. Keep screws grouped by location because Epson often uses different lengths. Release plastic clips gently with a non-marring tool instead of forcing the cover. Once the power-supply area is accessible, photograph every connector and cable route. Pull connectors by their housings, not by the wires, and check for locking tabs before applying pressure.
Support the board while removing its mounting screws so it cannot drop onto the chassis or pull on a cable. Lift it only after confirming that every connector, ground wire, and retaining screw is free. Do not place the board on a conductive surface. If the printer has no power, inspect the AC inlet, fuse, connectors, visible burn damage, and cable continuity, but remember that a blown fuse may be the result of another failed component rather than the original cause.
Common mistakes include copying removal steps from a different Epson model, mixing screw lengths, damaging a ribbon or harness while lifting the cover, and replacing a fuse without diagnosing the short that opened it. Repeated power-on tests can cause additional board damage when a short remains.
Because this repair involves mains voltage and possible board-level diagnosis, professional service is recommended if you are uncertain at any point. BCH Technologies can assist with EPS-135 testing, power-supply repair, and mainboard diagnosis; visit BCH Technologies [https://bchtechnologies.com].
