Epson L1800 Procolored Printer Beeping and Not Powering On: What It Means and How to Fix It

Question:
I have a Procolored L1800 printer that recently started beeping and won't power on. I've had several printhead issues, which I believe may be caused by bad ink. I cleaned and reinstalled the printhead, and it worked for about 100 prints before getting clogged again, even with regular maintenance. After cleaning it this last time, the printer shut off suddenly and now just beeps. I suspect the ink might be expired or low quality. I'm located in North Carolina and can bring it in for repair - what's your availability and the possible cost?

Answer:

Now, let's go through what's likely happening with your Procolored Epson L1800 printer and what steps you can take next.

1. Understanding the Beeping and Power Failure

When your L1800 beeps and won't power on, it usually points to a short circuit on the mainboard, often caused by ink or moisture entering the printhead's electrical system. If you noticed the issue occurred immediately after reinstalling or cleaning the printhead, that's a strong sign that some ink has reached the printhead contacts, leading to a short that damages the board's power components.

In your case, the printer cutting off suddenly suggests the mainboard's power protection circuit was triggered, and the board may now be damaged or "fried." Unfortunately, this is a common result of printhead shorts, particularly after deep cleanings or the use of high-viscosity DTF or Procolored inks.

2. Most Likely Damaged Parts

From your description, the following parts may need attention or replacement:

• Mainboard: Needs inspection and repair due to the short.

• Printhead: Even though it's only a month old, it's likely damaged by the short.

• FFC (Flat Flexible Cable): Should always be replaced after an electrical failure because even small burn spots can damage the next printhead.

At BCH Technologies, a typical repair like this would involve mainboard repair, FFC cable replacement, and printhead replacement, followed by a full test and maintenance inspection. However, we've been fully booked throughout the year with no foreseeable openings at the moment. You can find more information about our repair rates and procedures on our DTF/DTG Whole Printer Diagnostic and Repair page (https://bchtechnologies.com/collections/printer-repair-service/products/dtf-dtg-ecosolvent-whole-printer-diagnostic-fee-repair-labor-deposit-limited-opening).

3. Is the Ink Really the Problem?

While it's possible that low-quality or expired ink could contribute to clogging, it's more likely that the maintenance routine or ink circulation system is the real cause of your issues. The Procolored L1800 uses high-viscosity white ink that requires frequent agitation and proper filtration.

Here's what we recommend:

• Install an inline filter on the white ink line to prevent pigment buildup. You can find our recommended DTF Ink Filter with C3 Connections (https://bchtechnologies.com/products/dtf-ink-filter-with-c3-connections-for-high-viscosity-white-and-color-inks). You only need one filter for the white channel.

• Check the white ink circulation pump and tubing. If the pump isn't working properly, pigment will settle in the line, causing repeated clogs.

• Run daily white ink circulation or gentle agitation. This prevents pigment from hardening in the dampers or printhead.

The Procolored brand often recommends minimal maintenance, but in real-world usage-especially in DTF environments-more thorough maintenance is necessary to prevent clogs and damage. I cover these topics in several of my videos on our YouTube channel (https://youtube.com/@bchtechnologies), where I demonstrate how to properly clean, maintain, and protect your printhead and ink lines.

4. Preventing Future Board Damage

After repair or replacement, always ensure that the printhead is completely dry before reinstalling, that ribbon cables are inserted firmly and in the correct direction, and that static discharge is minimized by working in a grounded environment. Even a small drop of ink or moisture on the cable pins can cause an electrical short when power is applied.

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 or live repair assistance. However, we offer in-person diagnostic and repair services through our local repair facility (https://bchtechnologies.com/printer-repair-service). Due to high demand, our queue operates on a first-come, first-served basis, and it may take a few weeks before drop-off. Our repair options include both full printer and part-specific services.

We understand that our rates might not be the most affordable, so if you prefer to troubleshoot on your own, we encourage you to explore self-help resources on YouTube (https://youtube.com/@bchtechnologies). You can use the search icon near the "About" section to find videos by topic - a fast and effective way to locate the tutorials you need.
