Epson SureColor F570 Printing Blank Pages: How to Diagnose Clogged or Damaged Printhead Nozzles

Question

I have an Epson SureColor F570 that is printing completely blank pages. I have already tried Power Cleaning and other cleaning procedures, but nothing has helped. Could the printhead nozzles be damaged, and if so, how can damaged nozzles be fixed?

Answer

In your case, the fact that the Epson SureColor F570 is producing completely blank pages even after Power Cleaning is an important clue. This is different from a normal nozzle clog where only a few lines or colors are missing.

The F570 uses an Epson PrecisionCore MicroTFP printhead with four ink channels. Epson also incorporates nozzle-verification technology into this printer. (Epson) If the printer is producing absolutely nothing on the nozzle check-not even a small amount of cyan, magenta, yellow, or black-the problem may involve more than several clogged nozzles.

First, Determine Whether the Nozzles Are Actually Damaged

The term "damaged nozzle" can describe several different conditions.

A nozzle can simply be clogged with dried ink. In that situation, the nozzle itself may still be physically and electrically functional, but ink cannot pass through it.

A printhead can also suffer from air in the ink-delivery system, preventing ink from reaching the printhead. If the head does not have a sufficient supply of ink, cleaning cycles will not necessarily solve the problem.

There can also be a problem with the capping and pumping system. During a cleaning cycle, the printer normally relies on the maintenance system to pull ink through the printhead. If the cap does not seal correctly or the pump cannot generate sufficient suction, repeated cleaning cycles may consume time and maintenance-box capacity without successfully priming the printhead.

Finally, there can be genuine physical or electrical printhead damage. If the nozzle plate or internal piezoelectric elements are damaged, cleaning will not restore those nozzles. Individual PrecisionCore nozzles are not normally repaired one at a time; once the printhead itself has suffered permanent internal damage, replacement of the printhead or printhead assembly is generally the practical repair.

Start With a Nozzle Check

Before doing additional cleaning, print a nozzle check directly from the printer's maintenance menu.

This is more useful diagnostically than repeatedly sending normal print jobs.

If portions of the nozzle pattern appear, even if they are severely broken, the printhead is at least firing some ink. That points more strongly toward clogging, restricted ink delivery, air, or maintenance-station problems.

If the nozzle check is completely blank across every color, I would be more suspicious of an ink-delivery/priming problem, severe printhead blockage, maintenance-system failure, or an electrical printhead problem rather than a handful of ordinary clogged nozzles.

Epson specifically recommends using a nozzle check when the printhead moves but nothing appears on the paper. (Epson Support)

Be Careful About Repeated Power Cleanings

I would not continue running Power Cleaning over and over.

On the F570, Epson calls this function Powerful Cleaning. Epson specifically notes that this process consumes a significant amount of ink and recommends having the ink tanks at least one-third full before running it. If the nozzles remain clogged afterward, Epson recommends turning the printer off and leaving it overnight before proceeding further. (Epson Support)

Repeated cleaning cannot repair a physically damaged printhead. If the real problem is a poor cap seal, defective pump, blocked ink path, air entering the system, or an electrical failure, additional cleanings can simply consume large quantities of ink.

Consider the F570's Power Ink Flushing Function

There is another maintenance procedure on this particular model that is worth distinguishing from Powerful Cleaning: Power Ink Flushing.

On the F570, this is available under:

Settings → Maintenance → Power Ink Flushing

This procedure replaces the ink inside the ink tubes and can sometimes help when normal cleaning does not adequately restore ink flow. Epson warns that the tanks should be completely refilled before performing it, that the procedure consumes substantially more ink than normal or Powerful Cleaning, and that it can shorten the maintenance box's service life. (Epson Support)

If you have already performed a Power Ink Flushing correctly and the nozzle check remains completely blank, I would stop repeating automated cleaning procedures and begin looking for a mechanical, ink-delivery, or printhead failure instead.

Check the Ink Supply Before Condemning the Printhead

Before replacing a printhead, confirm that the printhead is actually receiving ink.

A printer can have full tanks and still fail to deliver ink correctly to the head.

Some possibilities include:

• Air introduced into the ink-delivery system.

• A restriction somewhere between the tanks and printhead.

• Dried or contaminated ink.

• An improperly primed ink system.

• A maintenance pump that cannot pull ink through the head.

• A capping station that does not seal tightly against the printhead.

• A heavily contaminated or dried capping surface.

• A printhead that has dried internally after sitting unused for a long period.

This distinction is important because replacing a perfectly good printhead will not fix a printer whose real problem is that ink never reaches the head.

Inspect the Capping Station and Maintenance System

The capping station is particularly important when a printer refuses to recover through cleaning.

When the printhead parks, the cap should make a good seal against the printhead. During cleaning, the pump uses that sealed connection to draw ink through the nozzle plate.

If the cap is dirty, dried out, deformed, incorrectly positioned, or unable to seal against the printhead, the pump may pull mostly air instead of ink.

Similarly, if the waste-ink pump or associated tubing is blocked or malfunctioning, the printer may go through the motions of a cleaning cycle while accomplishing very little.

If you are comfortable performing printer repairs, this area would be worth inspecting before concluding that the PrecisionCore printhead itself has failed.

A Completely Dry Printhead Is More Difficult to Recover

If the F570 has been sitting unused for a significant period, dye-sublimation ink can dry in the nozzles and internal ink pathways.

At that point, automated cleaning may no longer be sufficient.

However, manually cleaning a PrecisionCore printhead requires considerable caution. Applying excessive pressure through a printhead can damage its internal structures. Forcing cleaning liquid through the head with a syringe is particularly risky because the internal channels and nozzle plate are designed for extremely small, controlled fluid movement.

So, I would not assume that "more pressure" means "better cleaning." A partially recoverable printhead can sometimes become permanently damaged by an overly aggressive manual cleaning attempt.

What If the Nozzles Are Actually Physically Damaged?

If the nozzle plate has been scratched, chemically damaged, delaminated, or otherwise physically compromised, there generally isn't a practical way to repair individual nozzles.

Likewise, if the piezoelectric firing elements inside the PrecisionCore head have electrically failed, cleaning fluid will not solve the problem.

At that point, the realistic repair is usually printhead replacement.

Before purchasing an expensive replacement printhead, though, I strongly recommend verifying the ink supply and maintenance system first. You don't want to install a new printhead only to discover that the original problem was a failed pump or another component preventing ink from reaching the head.

Electrical Problems Can Also Produce Blank Pages

There is another category worth considering if absolutely no ink is firing: the printhead's electrical system.

A loose or damaged printhead cable, contaminated electrical contacts, failed printhead electronics, or a main-board/head-driver problem can potentially prevent the printhead from firing even though the carriage continues moving normally.

This type of failure behaves very differently from a simple clog.

For example, if the printer appears to operate normally, accepts print jobs, moves the carriage and feeds paper but consistently outputs completely blank nozzle checks after the ink-delivery system has been verified, an electrical problem becomes more plausible.

Be especially careful around printhead cables. Connecting or disconnecting printhead FFC cables while power remains in the printer can damage both the printhead and mainboard.

Error Codes

You did not mention a specific F570 error code or maintenance code, so there isn't an error code for me to interpret from the information provided.

If the printer does display one later, record the complete code before resetting or restarting the machine. Epson's F570 documentation distinguishes between maintenance-request codes and printer-error codes, and those codes can considerably narrow the diagnosis. (Epson Support)

Based solely on the symptom you described-completely blank output after extensive cleaning-I would investigate the printer in roughly this order:

1. Print a nozzle check directly from the printer.

2. Confirm all ink tanks have sufficient ink.

3. Determine whether any color at all appears on the nozzle check.

4. Avoid repeatedly running Powerful Cleaning.

5. If not already performed, consider the F570's Power Ink Flushing procedure according to Epson's instructions.

6. Verify that ink is actually reaching the printhead.

7. Inspect the capping station, pump, and maintenance system for proper operation.

8. If ink delivery and maintenance functions are confirmed good but the printhead remains completely blank, investigate the printhead and its electrical connections.

9. Consider printhead replacement only after the supporting systems have been ruled out.

Addressing printer issues can be complicated because so much of the diagnosis depends on physically observing and testing the machine. For that reason, we're not able to provide remote troubleshooting, step-by-step repair support, or individualized remote printer-repair assistance.

We do offer an in-person evaluation and repair service through our BCH Technologies printer diagnostic and repair facility [https://bchtechnologies.com/printer-repair-service]. Because of the high demand for this service, repairs are handled on a first-come, first-served basis, and it may take a few weeks before a printer can be scheduled for drop-off. Our services are structured so that we can repair either a complete printer or, in some situations, specific components, with instructions available on how to proceed.

We also recognize that our repair rates may not be the most economical option for every situation. Because of that, we strongly encourage self-help and online research whenever you're comfortable working on the printer yourself.

A good place to start is YouTube, including the BCH Technologies YouTube channel [https://youtube.com/@bchtechnologies]. Once you're on our channel homepage, use the search icon near the channel menu to search for the specific problem you're working on. I receive dozens of questions every day asking whether we have a video covering a particular repair. After creating printer-repair videos for more than nine years, it is difficult for me to remember every video we've published, so searching the channel is usually the fastest way to locate the relevant material. YouTube may also recommend helpful videos from other creators covering the same repair.

Thank you again for reaching out and for supporting BCH Technologies. I hope this gives you a clearer way to determine whether you're dealing with a recoverable ink-flow problem or an F570 printhead that has actually failed.
