XP600 Erasmart with Hoson Board Not Printing Ink and Stuck Initializing: Software Reset vs. Board-to-Head Connection Troubleshooting

Question: I have an XP600 Erasmart with a Hoson board. After a computer mishap, the printer stopped printing any ink. I replaced the printhead and head cables and followed support steps, but nothing works. Now it won't finish initializing and there's a yellow light blinking on the print board. Is this a software/settings issue, can someone check it remotely, and how do I run the diagnostic program?

Answer: 

First, I'm generally aligned with the manufacturer's direction here (and why)

From what you described-sudden "no ink output," followed by replacing the head and cables, and now the printer won't get past initialization with a blinking yellow light on the print board-this pattern most often points to a hardware communication or power/drive issue in the printhead circuit, not a normal "print settings" problem.

A laptop "cat event" can absolutely scramble software windows and even change driver settings, but it usually does not cause:

• a printer to stop outputting ink entirely (across all channels), and then

• become stuck initializing, and

• show a status/alert light on the print board

Those symptoms tend to show up when the controller detects a fault in:

• printhead signal lines,

• printhead power delivery,

• carriage/sub-board communication,

• ribbon/FFC cable orientation or seating,

• blown driver components or shorted head circuits,

• or a short/open connection between the main board and the carriage/sub-board.

In short: software can disrupt printing, but the "stuck initializing + board warning light" is usually the printer protecting itself from a detected electrical/communication fault.

What the blinking yellow light on the print board often indicates

On many Hoson-board-based DTF systems (including XP600 setups), a blinking yellow indicator on the print board can correlate with one of these conditions:

• Main board can't communicate with the carriage/sub-board

• Head data lines not reading correctly (open connection, reversed cable, wrong pin contact)

• Head power fault (overcurrent/short detected)

• Initialization halts because the head/sub-board check fails

The most common root cause (especially after cable replacement) is simply this:

A cable/FFC is not fully seated, seated crooked, flipped the wrong direction, or the locking tab is not engaged.

Even a tiny misalignment can prevent initialization and produce a warning light.

The #1 most common failure point: board ↔ sub-board (top of printhead) connection

Your proposed diagnosis is right on target: the connection between the main board and the sub-board on top of the printhead/carriage is the usual culprit.

Here's why this point fails so often:

• The carriage moves constantly, flexing cables over time

• FFC contacts are delicate and can develop micro-cracks or worn traces

• A head replacement often involves disconnecting/reconnecting multiple cables, and one imperfect connection can stop everything

• Some systems have multiple stacked boards (main + daughter/sub-board) and one connector being loose is enough to halt initialization

What to check (most important items first)

1. Power OFF and unplug before touching anything (important for safety and to prevent board damage).

2. Reseat every FFC/ribbon cable:

   • Remove the ribbon, inspect the contacts, and reinsert straight and fully.

   • Make sure the locking latch/tab is actually clamped down.

3. Check orientation:

   • Many ribbons can be inserted upside down; that can cause "dead printer" behavior or initialization lock.

4. Inspect for bent pins, torn traces, or burn marks:

   • If any ribbon has a crease line right at a bend point, that's a red flag.

5. Inspect the carriage/sub-board on top of the printhead:

   • If there's corrosion, liquid residue, or signs of overheating, initialization may fail to protect the system.

6. Check ground and power connectors:

   • A loose ground reference can produce erratic initialization and "no ink firing."

If the printer was printing before and then abruptly stopped firing ink, one additional possibility is:

• the original printhead shorted and damaged a driver circuit, and then the replacement head can't initialize because the driver circuitry is already compromised.

This is especially plausible if the system went from "no ink output" to "can't initialize" after hardware changes.

Why "no ink at all" can happen even with cleanings

If a DTF printer produces no ink output at all, across all channels, it's often not a clogging problem. Common electrical causes include:

• Head not firing because the data/power lines aren't reaching it

• Sub-board failure (the head never receives firing signals)

• Incorrect head cable installation (wrong cable type, wrong orientation, wrong seating)

• Blown fuse / driver on a board that supplies the head firing voltage

• Firmware/board fault that stops firing when it detects an abnormal condition

Support teams often start with cleanings because that's the least invasive step, but in a "zero output" situation, cleaning routines can be irrelevant if the head isn't being driven electrically.

About the "software issue" concern and remote checking

You asked whether there are remote services to check software settings. In general, settings issues can cause:

• wrong color output

• wrong print mode

• print not sending

• misaligned prints

• wrong ICC/profile

• wrong resolution/pass settings

But software issues rarely cause:

• no ink output plus

• stuck initializing plus

• board warning light

So while it's understandable to suspect the laptop event, your current symptoms strongly suggest a hardware handshake/fault, not a typical driver-setting problem.

How to access diagnostics and error logs (in general terms)

You mentioned "How do I run the diagnostic program?" On many Hoson-based systems, there is typically:

• a control software suite used for configuration/maintenance, and

• a factory/service login mode that can expose error logs, sensor states, and initialization faults.

However, the exact steps vary by:

• Hoson board model (there are multiple)

• the printer brand's software bundle

• the locked-down "factory" credentials policy of that manufacturer

What I can tell you at a high level (without guessing brand-specific passwords or menus) is that the diagnostic path usually looks like:

• Open the printer/control software → look for Maintenance / Engineer / Factory / Service menus

• Locate Error Log / Alarm Log / System Log

• Export or screenshot the codes and timestamps

• The log commonly reveals whether it's:

  • head connection error,

  • carriage board communication error,

  • head voltage abnormal,

  • initialization handshake failure,

  • or board-level protection shutdown.

If you can retrieve that log, it often points directly to the board↔sub-board or head circuit fault you're already circling.

What I would prioritize in your case (quick triage order)

Given your timeline (bought April last year, sudden failure, replaced head and cables, now stuck initializing), the most productive order is:

1. Reseat and verify every board-to-sub-board and head ribbon connection (orientation + locking tabs)

2. Check the sub-board on top of the printhead for damage/residue/overheat

3. Confirm the correct XP600 cable set (not just "fits," but correct spec and pinout for that system)

4. Pull the error log in factory/service mode (if available in your control software)

5. If still stuck initializing, consider board driver damage from an earlier electrical fault (especially if the first symptom was total no-fire)

Addressing printer issues can be a complicated affair because the problems are so hands-on and mechanical/electrical in nature. For that reason, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility, Printer Repair Service (https://bchtechnologies.com/printer-repair-service). Because demand stays high, we run on a first-come, first-served basis, and it may take a few weeks before we can schedule a drop-off for your printer. Our services are structured to repair either an entire machine or specific parts, with clear instructions on how to proceed. We'll also be honest that our pricing isn't the most economical, so we strongly encourage self-help through online research first. You can start on YouTube or by visiting our channel homepage at BCH Technologies on YouTube (https://youtube.com/@bchtechnologies). To find the most relevant video quickly, use the search icon next to "About" on the right side of the menu bar. I receive dozens of messages each day asking for a video on a specific topic, and after creating videos over the last nine years, it's difficult to remember every single one-so YouTube search is the fastest route. YouTube may also suggest helpful videos from other creators that match your exact symptoms.
