Epson ET-8550 DTF Conversion vs. Kevin R2R Printer: Which Option Is Best for Occasional and High-Volume Printing?

Question

I follow BCH Technologies on YouTube and subscribe to the newsletter. I am receiving a replacement Epson EcoTank ET-8550 after my previous printer developed error code 031006 following a DTF conversion.

I had converted the original ET-8550 for DTF printing and used CADlink RIP software. Because the printer was still under the factory warranty, I removed the DTF ink, restored the printer as closely as possible to its original condition, and returned it. Epson is now sending me a replacement.

After watching the Kevin R2R video and reviewing the printer on the BCH Technologies website, I am trying to decide between two options:

  1. Send my replacement Epson ET-8550 to BCH Technologies for a professional DTF conversion. Including shipping, labor, and parts, I estimate the total cost would be approximately $850 to $1,000.

  2. Purchase the Kevin R2R DTF printer from BCH Technologies. After shipping and taxes, I estimate the total cost would be approximately $2,700 to $2,800.

I make a fair number of T-shirts, primarily for family members, friends, coworkers, and school-related projects. I have occasionally completed batches of more than 80 shirts, but that is not my normal production volume.

What are the differences between these systems, and which option would be more appropriate for the way I use a DTF printer?

Answer

The most important point to clarify is that the Kevin R2R and the Kevin V2 ET-8550 conversion system are two different types of DTF printers. They are designed for different production habits and should not be evaluated only by comparing their purchase prices.

What Is the Kevin R2R DTF Printer?

The Kevin R2R is a dedicated roll-to-roll DTF printer. It is not an Epson ET-8550 that has simply been converted to use DTF ink.

A roll-to-roll printer feeds DTF film from a continuous roll rather than requiring the operator to load individual sheets. This makes it better suited to regular production, repeated designs, longer print runs, gang sheets, and larger batches.

The main advantage is workflow efficiency. Once the roll is aligned and the printer is operating correctly, the user can print multiple designs or longer jobs without manually loading a new sheet after every print.

However, a roll-to-roll printer generally requires more consistent operation and maintenance. White DTF ink contains pigments that can settle inside the ink system. If the printer remains unused for long periods, the white ink can separate, accumulate inside the tubing, settle in the dampers or ink tanks, and contribute to nozzle loss or ink-flow problems.

For that reason, the Kevin R2R is generally more appropriate for someone who prints regularly. A user may be able to leave it unused for two or three days, depending on the maintenance procedure and environmental conditions, but it should not normally be treated like a household printer that can remain untouched for several weeks.

A roll-to-roll machine is a better match when:

  • DTF printing is performed several times each week.

  • The user regularly produces larger batches.

  • Continuous film is more convenient than individual sheets.

  • The user is prepared to perform daily or scheduled maintenance.

  • Faster production and reduced manual film handling justify the higher cost.

  • The printer will be operated as production equipment rather than as an occasional hobby machine.

The Kevin R2R may also provide more room for growth. Even though batches of 80 or more shirts are not currently normal for you, a roll system could make those jobs substantially easier when they occur. It would also be more practical if your order volume increases in the future.

What Is the Kevin V2 ET-8550 Conversion?

The Kevin V2 is our conversion approach for turning an Epson ET-8550 into a sheet-fed DTF printer. It is not a roll-to-roll system.

The converted ET-8550 prints on individual DTF film sheets. Depending on the film, setup, and conversion configuration, the user normally loads and prints one sheet at a time. This process requires more operator involvement, but it can be appropriate for smaller businesses, schools, home-based operations, hobbyists, and users who print only when a project comes up.

The Kevin V2 is also evolving, and it will soon move toward a Kevin V3 configuration as we continue improving the conversion program. Changes between versions may involve ink delivery, maintenance, film handling, tubing arrangements, white-ink management, or other components intended to make the converted printer more practical and reliable.

The converted ET-8550 may be a better match when:

  • Printing is performed occasionally rather than every week.

  • There may be gaps of several days or even a few weeks between projects.

  • Most orders are small or medium-sized.

  • The user does not need continuous roll printing.

  • The lower initial investment is important.

  • Individual sheet loading is acceptable.

  • The printer is used mainly for family, friends, coworkers, school activities, and occasional group orders.

Although no DTF printer should be abandoned without maintenance, a sheet-fed ET-8550 conversion can be easier to manage for a user whose production schedule is irregular. It is still necessary to protect the printhead, circulate or agitate the white ink, inspect the capping station, keep the ink system sealed, and prevent the nozzles from drying. However, the overall configuration may be more appropriate for someone who does not operate a DTF printer continuously.

Which Option Better Matches Your Workload?

Based on the production pattern you described, the converted ET-8550 appears to be the more practical option unless you expect your printing volume to increase significantly.

You mentioned that you make a fair number of shirts but primarily print for family, friends, coworkers, and school-related purposes. You have completed batches of more than 80 shirts, but those larger projects are occasional rather than routine.

That usage pattern usually favors the Kevin V2 or upcoming Kevin V3 ET-8550 conversion. The lower cost is one consideration, but the more important factor is that a sheet-fed system aligns better with irregular use.

The Kevin R2R would make more sense if you expected to print multiple times each week, consistently produce larger gang sheets, take regular customer orders, or develop the operation into a more active apparel business.

The R2R is not necessarily "better" in every situation. It is a more production-oriented machine, but the benefits of continuous roll printing are most valuable when the printer is used frequently enough to justify its cost, maintenance requirements, and larger working footprint.

For an occasional user, purchasing a roll-to-roll printer can create a situation where the machine is more capable than necessary while also demanding more attention than the user's workload naturally provides.

Cost Should Not Be the Only Consideration

Your estimated cost difference is substantial. A professionally converted ET-8550 may cost approximately $850 to $1,000 after conversion expenses and transportation, while the Kevin R2R may reach approximately $2,700 to $2,800 after shipping and taxes.

However, the purchasing decision should also include the following operating considerations:

  • Frequency of printing

  • Film consumption

  • White-ink maintenance

  • Cleaning frequency

  • Replacement-part availability

  • Printhead risk

  • Space requirements

  • Production speed

  • Sheet loading versus continuous roll feeding

  • The value of your time during large jobs

  • Your willingness to perform preventive maintenance

A roll-to-roll printer could save significant time during an 80-shirt project. In contrast, that time savings may not justify the additional investment if such jobs occur only a few times each year.

A converted ET-8550 requires more manual film handling, but its lower entry cost may allow you to reserve funds for ink, film, powder, curing equipment, replacement dampers, cleaning solution, maintenance supplies, and possible future repairs.

Understanding Epson Error Code 031006

The 031006 error on an Epson ET-8550 is commonly associated with a printhead-related electrical or temperature-detection problem. It may indicate that the printer's control system has detected an abnormal condition involving the printhead, head temperature circuit, flexible flat cables, printhead driver circuitry, or mainboard.

In a DTF-converted printer, several conditions may contribute to this type of failure:

  • DTF ink leaking onto the printhead contacts

  • Moisture or cleaning solution entering the printhead connector

  • A damaged or improperly seated flexible flat cable

  • Contamination on the cable contacts

  • A short circuit within the printhead

  • A damaged thermistor or temperature-sensing circuit

  • A failed printhead driver component on the mainboard

  • Power being connected or disconnected while residual voltage remains in the printer

  • Ink accumulating around the printhead cable connections

  • Improper cable alignment after servicing

Error code 031006 should not automatically be interpreted as proof that only the printhead has failed. A defective printhead can damage the mainboard, and a defective mainboard can sometimes damage a replacement printhead. Installing another printhead without testing the associated circuitry can therefore create additional risk.

Before replacing a printhead, a technician should inspect the cables, connectors, printhead contacts, fuse circuits, driver components, and surrounding areas for evidence of ink contamination, corrosion, overheating, or an electrical short.

A Factory Replacement Does Not Guarantee DTF Compatibility

It is also important to understand that Epson manufactures the ET-8550 for use with Epson-compatible aqueous ink and its intended consumer printing system. DTF conversion changes the ink chemistry, film path, maintenance routine, and operating conditions.

A replacement ET-8550 may work perfectly as a standard photo printer but can still face additional risks after conversion. These risks include nozzle clogging, ink separation, capping-station contamination, printhead cable damage, ink leakage, film feeding problems, and electrical failures.

A professional conversion can reduce avoidable mistakes and improve the configuration, but no conversion eliminates all risks. DTF printing places different demands on the printer than the original design intended.

You should also assume that converting the replacement printer may affect or eliminate the factory warranty. Even when a printer is restored to its original appearance, the manufacturer may identify nonstandard ink residue, modified components, or evidence of previous conversion.

Our Practical Recommendation

Based on the information provided, the converted ET-8550 is likely the more suitable choice for your present needs.

Your printing appears to be meaningful but intermittent. You sometimes handle large batches, yet you do not operate the printer as a continuous production machine. A sheet-fed Kevin V2 or upcoming Kevin V3 conversion would likely provide enough capacity without requiring the investment and operating commitment of the Kevin R2R.

The Kevin R2R would become the stronger choice if your work develops into frequent weekly production, regular paid orders, repeated large batches, or a business that depends on faster roll-based output.

Before sending the replacement printer for conversion, we recommend confirming which conversion version is currently available, what components are included, what maintenance procedures will be required, and whether shipping both ways is included in the estimate. It would also be helpful to compare the total conversion cost with the value of keeping the replacement ET-8550 as a standard printer and purchasing a separate dedicated DTF machine later.
