Epson WF-2650 Printed Poorly, Then Printed Blank After Using BCH Green Cleaning Solution: What Likely Happened and What to Check Next

Question: I have an Epson WF-2650. Print quality was poor, so I used BCH Premium Green cleaning solution (diluted) on each of the four colors. The cleaning seemed to go okay, but afterward the printer won't print anything-pages come out blank, and even the nozzle check prints nothing. This is my second time using the BCH solution. The first time (May 2025) it worked perfectly and the printer printed like new. This time I used the diluted solution I mixed last May. I also have the clear solution and can try it, but I don't want to damage the printhead without guidance. What should I do?

Answer: 

Based on what you described, the key clue is this: the cleaning process seemed to go okay, but afterward you get a totally blank nozzle check (no black, no colors). When everything disappears at once, the issue is usually not "one stubborn clog." It's usually one of the following system-wide problems:

Why the WF-2650 can suddenly print completely blank after cleaning

1) Air got introduced into the ink delivery path (most common after manual cleaning)

When you flush or introduce cleaning solution into the lines/dampers, it's possible to introduce air pockets. Epson ink systems don't handle air well-air can act like a "cap" that prevents ink from reaching the nozzles.

What that looks like:

• Printer runs normally (no error), but prints blank

• Nozzle check shows nothing at all

• Cleaning cycles don't bring anything back quickly

This is especially likely when the printer was already printing poorly (partial starvation/clogging), then cleaning changed the fluid dynamics in the line.

2) The capping station or pump is clogged, so the printer can't prime ink properly

Even if the printhead itself is okay, the WF-2650 depends on the maintenance station (cap + pump) to pull ink through during cleaning cycles. If the cap/pump path is clogged with dried ink, cleaning cycles won't pull ink through the head, and you can end up with blank prints.

Common signs:

• Cleaning cycles run but do not restore any nozzles

• You may see ink pooling around the cap area, or the cap looks heavily stained/sludged

• The printer behaves like it's cleaning, but nothing changes on nozzle checks

3) Old mixed/diluted solution changed over time (possible)

You mentioned you used a diluted solution mixed in May 2025, and it worked well when fresh back then. Over many months, a premix can change due to:

• evaporation (making it more concentrated),

• contamination (bacteria/dust/ink residue introduced during prior use),

• or separation/chemical drift depending on storage conditions.

That doesn't automatically mean "it damaged the printhead," but it can mean the mixture behaves differently than expected and could contribute to:

• more air being introduced,

• inconsistent viscosity,

• or residue/microbial growth that affects flow.

4) Electrical printhead failure is possible-but usually not the first assumption

If a WF-2650 head electrically fails, you can get blank output. However, it's less common for a healthy head to suddenly fail exactly at the moment of cleaning unless there was:

• overheating from repeated cleanings,

• fluid intrusion onto electronics,

• or the printer was already near end-of-life.

So we usually rule out prime/pump/air issues first.

What to do next (safe, practical steps that don't "force" the head)

Step 1) Stop using the old diluted mix for now

Since the current issue started right after using an older premix, the safest approach is to pause on that batch. If you plan to use cleaning solution again, it's best to use:

• a fresh dilution (if dilution is required), made with distilled water,

• in a clean, sealed container,

• and labeled with date.

Step 2) Run a nozzle check and listen/observe the cleaning behavior

You've already done nozzle checks and they're blank-good diagnostic info. The next useful observation is: during a head cleaning cycle, do you hear the pump working normally? If the pump sound is weak/odd or ink isn't moving, it supports the "maintenance station can't prime" theory.

Step 3) Let the printer rest, then do limited cleanings (avoid overheating)

A lot of people respond to blank nozzle checks by running cleaning after cleaning. On Epson workforce models, too many consecutive cleanings can:

• overheat the head,

• increase air in the system,

• and flood the waste system without restoring flow.

A safer pattern is:

• allow rest time between cleanings,

• do a nozzle check after each attempt,

• and avoid long back-to-back sessions.

Step 4) Focus on priming and the maintenance station (cap/pump)

When everything prints blank, a major suspect is that ink is not being pulled through the head at all. The limiting factor is often the capping station seal and the pump pathway.

If the cap isn't sealing:

• cleaning cycles won't generate suction,

• ink won't move into the head,

• and the nozzles remain dry/airlocked.

If the cap/pump is clogged:

• suction is blocked,

• the printer can't prime,

• and blank nozzle checks persist.

Practical check (non-invasive):

• With the printer off, open the top and locate where the head parks (capping station area).

• If it's heavily crusted with ink sludge, the station may need cleaning/service.

Step 5) Be cautious with any method that pushes fluid through the head

You mentioned you have the "clear solution" and can try it. I understand the instinct, but the risk isn't the color of the solution-it's the method and pressure.

In general:

• Pulling (vacuum priming through the cap) is safer than pushing fluid upward into the nozzles.

• Overpressure can damage internal channels or delaminate nozzle structures.

If you decide to use additional solution, the safest approach is to ensure the maintenance station is functional and the printer can prime normally, rather than forcing liquid through the head.

Why it worked last time but not this time

Your experience (worked perfectly in May 2025, now blank) is very common. Over time, these printers can develop:

• gradual ink starvation,

• thicker deposits in the maintenance station,

• and weaker priming performance.

So the same cleaning method that revived it once may not revive it the same way later-especially if the maintenance station/pump has gotten more restricted since then.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility: printer repair service (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis, so it might take a few weeks before we can get your printer in for drop-off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage: BCH Technologies on YouTube (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for reaching out, and I'm sorry you're dealing with a WF-2650 that suddenly went blank after cleaning. I truly appreciate your support of BCH Technologies and the channel, and I hope the explanation above helps you narrow it down to the most common causes-air in the ink path or a maintenance station/pump priming issue-before trying any more aggressive cleaning steps.
