Brother J6530DW Inkjet Cyan problems - trailing edge etc

[eunos]

So I've had problems with cyan coverage on this inkjet machine for a while. test pages etc have missing cyan bits. But docs printed using best quality settings would work ok.

I attach two scans of problem pages.

More recently, i've had a problem with a faded line on the trailing edge in Cyan. This may have started after testing printing onto just one 250gsm card sheet.

Any suggestions on what to do next?

- I've done initial and advanced purges from service menu many times.
- Used a syringe with head cleaning solution twice.
- Cleaned the used ink reservoirs

Cleaning the heads made quite the mess lower down in the machine. I've not managed to clear all that up yet, hence some streaks and splodges on the attached.

Seems the nozzles are clogged (probably compatible ink in use) - you can turn off and on the printer and cut the power during the printhead initial run so you can move it freely. Not you can clean the nozzles with a narrow cloth soaked in isoporopanol or something fancy that is available for cleaning printheads. The easiest way to get the cloth-stripe below the printhead is just to lay it down on the area were the printhead moves around and after this move the printhead above it. Now you can put the ends of the cloth back and forth. Also clean the rubber sealing of maintanance station where the printhead usually rests on. Afterwards the print results might look even worse at the beginning so you might have to run more advanced purge cycles. This usually leads to some more or less significant improvement at least.

thank you. they are indeed aftermarket inks.

you can unlock the printhead by holding down the home and cancel keys simultaneously. i'll try your suggestion tonight.

It's still in the manual, isn't it?

Perhaps, brother is kind of a "side hustle" for our company, so I know less about it technical wise compared to ricoh/km topics
