Understanding AWM 5542 Cable Markings on Epson L1800 DTF Printers: What You Really Need

Customer's Question:
I'm having trouble with my AOK DTF printer, which uses an Epson L1800 engine. I'm looking for a 4-pin cable labeled "AWM 5542 80C 60V VW-1 TOTOKU-P" for the printhead. I can’t seem to find that exact marking—what does this mean, and do you carry this cable?

Answer:

Clarifying AWM 5542 Cable Markings:
Let’s start by demystifying the AWM 5542 label you're seeing. The term “AWM 5542 80C 60V VW-1” is not a model number or a part unique to a specific printer. It’s a wire specification standard governed by Underwriters Laboratories (UL). Here’s what it means:

• AWM = Appliance Wiring Material

• 5542 = Style number denoting construction specs like insulation type and thickness

• 80C = Maximum temperature rating (80°C)

• 60V = Voltage rating (60 volts)

• VW-1 = Flame test rating

• TOTOKU-P = Manufacturer (in this case, likely Totoku Electric)

So, while these markings help identify the cable's technical standards, they don’t uniquely identify the cable’s function in the printer. Different manufacturers may use their labels, and you’ll often see the same cable described differently depending on the vendor.

What Matters More: Function, Not the Marking
To better help you, the key question is where this cable connects—because function and connector shape matter more than label:

1. If the cable is meant to connect directly to the printhead:
   We recommend our Printhead FFC Bundle Combo for Epson L1800 and similar models (https://bchtechnologies.com/products/printhead-ffc-bundle-combo-for-epson-l-1800-1390-1400-1410-1430-r260-r270-r360-13x2-9-pin?_pos=6&_sid=4ba7bb3d1&_ss=r)
   This bundle includes all the FFC (Flat Flexible Cable) types used for printhead connectivity and should fit your needs if the 4-pin cable is part of that connection group.

2. If the cable connects to the back of the carriage (not directly to the printhead)—typically the one connecting the CR (Carriage Return) and PW (Paper Width) sensors—then what you're looking for is:
   Our 13-Pin Page Width / CR Encoder Sensor FFC Cable (https://bchtechnologies.com/products/13-pin-page-width-cr-encoder-sensor-csic-ffc-cable-for-epson-l1800-1390-1430-dtf-dtg-printers?_pos=2&_sid=4ba7bb3d1&_ss=r)
   This is commonly used for signal transmission between carriage sensors and the mainboard.

If you’re still unsure where this cable connects or which version you need, please feel free to send us a photo or specify the exact slot or module it's associated with (e.g., printhead, board, sensor). We can match it more accurately that way.

Important Note on Troubleshooting Support:
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. It may take a few weeks before we can get your printer to drop it off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be the most efficient approach. Additionally, YouTube may suggest relevant videos from other channels that can assist you.
