Epson ET-2760 Prints Faintly, Then Nothing After Cleaning and Waste Tank Reset: Causes and What to Check Next

Question:
I have an Epson ET-2760 that first went from printing sparsely to not printing at all. Around the same time, the waste ink tank was full, so I replaced the waste tank and reset the waste ink counter. I also confirmed the ink reservoirs were full, reset things, and ran nozzle checks. I did multiple head cleanings and power cleanings. Eventually I used cleaning solution, and the printer printed again, but still only sparsely.

After waiting more than 12 hours, I injected cleaning solution into the printhead and removed the blotting paper. That seemed to go fine. I checked the dampers and saw they had only a small amount of ink in them, so I used a syringe on each damper and was able to pull ink into them and fill them. Then I ran another power cleaning and nozzle check, and after that nothing printed at all.

I also tried drawing ink from the ink line before it enters the damper, and ink does come into the syringe, so it seems like ink is available in the lines. I saw your extreme bone-dry cleaning video, but I am not sure how to reach that part or remove it because the video does not show that step. The video I watched is this YouTube video [https://www.youtube.com/watch?v=STCwMfQNI1Y]. At this point I am out of ideas and would appreciate your advice.

Answer:

From what you described, your ET-2760 most likely has an ink delivery problem, a printhead priming problem, or a printhead damage issue that became more obvious after repeated cleanings and manual priming attempts. The fact that it went from sparse printing to nothing at all is very important, because that usually means one of two things: either the printhead is no longer getting ink properly, or the nozzles are now completely air-locked or electrically damaged.

Let's break down the likely causes.

When a printer starts printing lightly or with many missing nozzles, the first suspicion is usually a partial clog. That is why head cleanings and power cleanings sometimes help at first. However, if too many cleaning cycles are done, especially power cleanings, the printer can actually make things worse. A power cleaning pulls a large volume of ink through the system. If there is an air leak, a weak damper, a sealing issue at the printhead, or poor ink flow from the tank side, the cleaning cycle can pull in air instead of solid ink, and then the printer can go from "printing poorly" to "printing nothing."

Your observation that the dampers only had a little ink in them is a strong clue. In a healthy ink delivery path, the damper area should not remain starved for long. If you had to manually draw ink into the dampers with a syringe, that tells us the printer may not be priming normally on its own. That can happen for several reasons:

1. Air trapped in the ink path
   Even though you can pull ink manually with a syringe, the printer's own suction system is much weaker than a hand syringe. A syringe can overcome resistance that the printer cannot. So yes, ink being present in the line does not necessarily mean the printer can successfully pull that ink into the head during operation.

2. Damper or seal problem
   If a damper is not sealing well, or if it was disturbed during service, the system may pull air instead of ink. On EcoTank models, even a very small leak in the ink path can prevent normal priming.

3. Capping station / pump problem
   The printhead relies on the maintenance station, cap, and pump assembly to create suction during cleaning cycles. If the capping station is not sealing tightly to the printhead, or if the pump is weak or clogged, cleanings will not properly pull ink through the nozzles. In that case, repeated cleaning just wastes ink and fills the waste tank without restoring print quality.

4. Printhead flooded, then air-locked
   After injecting cleaning solution into the printhead, sometimes the head temporarily prints because the fluid loosens dried ink. But if too much solution remains, or if the head is not fully re-primed with ink afterward, the nozzles may become diluted with cleaning fluid or filled with air pockets. Then the printer may stop printing altogether.

5. Electrical printhead failure
   If the printer was already printing sparsely for a while, there is also a chance the printhead itself has developed an electrical failure. A clog and an electrical failure can look similar at first on a nozzle check. The difference is that a clog often changes pattern somewhat after cleaning, while an electrical issue may stay dead or become completely blank. If a nozzle check is now producing a totally blank page even after ink has clearly reached the head, then electrical damage becomes a stronger possibility.

Regarding the waste ink tank and waste ink counter reset: that issue is usually separate from actual printing quality. The full waste tank condition can stop operation until serviced, but it usually does not by itself cause sparse printing. In other words, the waste tank being full happened at the same time, but it was probably not the root cause of the missing print. If your printer had displayed a waste ink warning or a "service required" message before reset, that would be related to the maintenance counter, not directly to the nozzle output.

As for error codes, you did not mention a specific numeric error code in your message. If the printer is showing any code on-screen now, that code matters and could change the diagnosis. For example, a maintenance or service-related message points in one direction, while carriage, paper path, or fatal hardware errors point in another. But based on the symptoms you described, the main issue appears to be loss of prime, poor suction, trapped air, or printhead failure rather than a specific panel error code.

Here is what I would check next, in order:

First, inspect the capping station and pump area. This is one of the most overlooked causes of "won't print after cleaning." If the cap top is dirty, warped, or unable to seal tightly against the printhead, the printer cannot draw ink through the head during a cleaning cycle. If the pump tubes are clogged with dried ink, suction will also be poor. A good test is whether the maintenance station is visibly pulling fluid into the waste line during a cleaning cycle. If it is not, the head may never reprime correctly no matter how much ink is in the lines.

Second, verify that the dampers are seated correctly and that no air was introduced where they attach. If they were removed or disturbed, even a slight sealing problem can create a no-print condition. Manual syringe priming should be done very carefully, because too much force can damage the head membrane or disturb the ink path.

Third, do not keep repeating power cleanings back-to-back. At this stage, more power cleanings may just consume ink and increase stress on the maintenance system. If the head is not primed correctly, repeated cleanings usually do not solve it.

Fourth, inspect whether the printhead is now full of cleaning solution instead of ink. If so, it may need a controlled re-priming process rather than more random cleaning cycles. Sometimes a head that printed faintly after solution injection will go blank because the ink never properly displaced the cleaning fluid.

Fifth, consider whether the printhead may be permanently damaged. If you have confirmed ink is available, the lines are not empty, the dampers contain ink, and the capping/pump system is functioning correctly, but the nozzle check is still completely blank, then the printhead electronics may have failed. On these models, that is unfortunately possible, especially after prolonged dry printing, heavy clogging, or aggressive cleaning attempts.

About the "extreme bone-dry cleaning" concept: that kind of procedure is generally used when the ink path or head has gone severely dry and ordinary cleaning no longer works. But getting to that stage often requires disassembly and access to parts that are easy to damage if you are unfamiliar with the ET-2760's internal layout. If the video does not show the removal steps, I would be careful about forcing anything apart. The ET-2760 is compact, and access to the head parking area, cap station, and ink path can be tricky.

So, the most likely practical conclusion is this:
Your printer probably does have ink available in the supply line, but the printer may no longer be able to properly pull and maintain ink at the printhead on its own. That points most strongly to the capping station/pump assembly, air leakage around the dampers or head connection, or a damaged printhead. The fact that a syringe can pull ink does not prove the printer's own cleaning system can do the same job under normal operating conditions.

Printer problems like this can be difficult because they are very hands-on by nature. For that reason, we are not able to provide remote repair troubleshooting or step-by-step repair support. We do offer an in-person evaluation and repair option through our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Because demand is high, service is handled on a first-come, first-served basis, and it may take a few weeks before we are able to accept a unit for drop-off. We can repair either an entire printer or selected components, and the service page explains how to proceed. That said, we understand our pricing may not be the lowest option, so we strongly encourage self-help research first. A good starting point is YouTube, including our BCH Technologies YouTube homepage [https://youtube.com/@bchtechnologies]. You can use the search icon near the "About" section on the right side of the menu bar to look for videos on your exact topic. I receive many questions every day asking whether we have made a video on one issue or another, and after so many years of publishing, the fastest way to locate a specific topic is usually YouTube search itself. It may also suggest useful videos from other creators that help with the same repair.

Thank you again for your kind words, your support, and for following our videos. We truly appreciate it, and we hope this gives you a clearer direction on what is happening with your ET-2760.
