My Epson L1800 printer is dead (no power) and I saw some replacement fuses for F1, F2. Are the fuses the same? There are no choices to choose which one I want to order

Regarding your trouble with Epson L1800, F1 is not what would stop the mainboard of your printer powering on. Of course, it helps to know what the fuses are in your machine. if you plug your main board back in and its still does not power up you have other issues potentially causing this.

Some of the general areas where you may examine are:

Power bridge transistors regulate the current to your entire printer. They are also the most likely part of this board to burn out and prevent a device from powering on.

FFC cables (Flexible Flat Cables) are flat, ribbon-like cables that can fray or disconnect, causing power loss to major components.

Power supply: If the power unit is not working, the system will be out of order, and you cannot power it on. Verifying that the power supply and its connections are in good condition is essential.

Logic Chips and Capacitors (the printer will work in part because both will help manage that low functioning or processing). Sala qué si falla se puede impedir que la impresora arranque.

The Transistor (Q601) is one of the elements that usually malfunctions if the mainboard isn't working. Sometimes, it stops the mainboard from working; sometimes, it allows it to turn on but prints very slowly.

If inspecting or altering these parts doesn't fix the issue, you will probably need to carry out a complete power evaluation of the system. However, due to the sheer number of potential problems, a proper diagnostic may require professional expertise.
