What Screwdriver Sizes Are Needed to Disassemble an Epson Inkjet Printer?

Question

I watched your video about disassembling and taking apart an Epson multifunction inkjet printer. What type and size of screwdriver bits do I need? Are Torx screws required, and what measurements should I look for?

Answer

For most Epson inkjet and multifunction printers, you usually do not need a Torx screwdriver for routine disassembly. Epson commonly uses Phillips-head screws throughout the printer.

The two most useful screwdriver sizes are:

• Phillips #2 screwdriver: Used for most standard exterior, frame, chassis, scanner-unit, and housing screws.

• Phillips #1 screwdriver: Used for smaller or more delicate screws around circuit boards, sensors, printhead components, cable brackets, control panels, and other compact assemblies.

A medium-length Phillips #2 screwdriver will handle many of the larger screws found on Epson printers. A Phillips #1 precision screwdriver is helpful when working in tighter spaces or removing smaller screws. In some models, an extra-long screwdriver shaft can also be useful because certain screws are recessed deep inside the printer frame.

Although people sometimes refer to any star-shaped or cross-shaped screw as a Torx screw, most of the screws visible in common Epson desktop printers are actually Phillips screws. Before purchasing Torx bits, inspect the screw head closely:

• A Phillips screw has a cross-shaped recess.

• A Torx screw has a six-pointed star-shaped recess.

• A Pozidriv screw resembles a Phillips screw but has additional smaller lines between the main cross slots.

Using the wrong driver can strip the screw head. A Phillips #2 bit may fit into a smaller screw but can damage it if excessive pressure is applied. Similarly, a Phillips #1 screwdriver may feel loose in a larger screw and can round off the screw head.

For most Epson printer repairs, a practical screwdriver set should include:

• Phillips #1

• Phillips #2

• A small flat-head screwdriver for releasing plastic tabs

• A precision screwdriver handle

• A long-shaft Phillips screwdriver for recessed screws

• Fine-tip tweezers for springs, clips, and ribbon-cable locks

Some Epson models may contain uncommon screws in specific assemblies, especially around motors, hinges, power supplies, or third-party modifications. However, these are exceptions rather than the standard. Begin with Phillips #1 and #2 screwdrivers and check each screw carefully before applying force.

It is also important to use a screwdriver that fits the screw head firmly. Apply steady downward pressure while turning slowly. If a screw does not move, do not immediately increase force. Check whether the screwdriver size is correct, whether the screw is hidden under a label or plastic cover, or whether another component must be removed first.

During disassembly, organize the screws by section because Epson often uses screws with similar-looking heads but different lengths. A long screw installed in the wrong location can damage wiring, plastic housings, circuit boards, or moving parts. Taking photos before removing each assembly can make reinstallation much easier.

When removing plastic covers, remember that screws are only part of the fastening system. Epson printers also use numerous plastic clips, hooks, and locking tabs. If a cover remains firmly attached after the visible screws are removed, do not pry aggressively. Look for hidden screws, recessed fasteners, or tabs along the edges.

For the printer shown in the referenced video, the safest general recommendation is to have both a Phillips #2 screwdriver for regular screws and a Phillips #1 screwdriver for finer screws. A Torx driver is generally not necessary unless you can clearly see a six-pointed star-shaped screw head on your particular printer.

Printer repair can be complicated because many problems require direct, hands-on inspection. For that reason, we are unable to provide individualized remote troubleshooting, repair recommendations, or step-by-step support for specific printer repairs. We do offer in-person evaluation and repair through our local printer diagnostic and repair facility [https://bchtechnologies.com/printer-repair-service].

Because demand is high, repairs are handled on a first-come, first-served basis, and it may take several weeks before an appointment or drop-off opening becomes available. Our services can cover either a complete printer or certain removable parts, with instructions provided for the appropriate service process. We also recognize that professional repair may not be the most economical option for every situation.

For this reason, we strongly encourage self-help through careful online research. You can begin with YouTube or visit the homepage of our BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies]. To locate a specific topic, use the search icon near the "About" section on the right side of the channel menu.

We receive dozens of questions each day asking whether we have videos covering particular repairs. Since we have produced printer-repair videos for more than nine years, it is difficult to remember every video by title. Using YouTube's channel-search function is usually the fastest and most reliable method. YouTube may also recommend helpful videos from other repair channels.

Thank you again for watching our videos, contacting BCH Technologies, and taking the time to ask your question. We appreciate your support and hope this information helps you select the correct tools before beginning your Epson printer disassembly.
