I tried a couple of second hand heads which were worn out. I also replaced the black cartridge a couple of times to eliminate that as a fault. I purchased this printer for £10.00 last week so I don't know its age. I have purchased other second hand printers over the last few years; I have 3 units in my shed with various faults, eg the appearance of being mains dead, the head moving but not printing, and the cleaning mech gears clattering and sounding is if the gear teeth are worn/stripped.
I cleaned the head by steaming it with the kettle. I have done this a few times in the past with good results.
The second hand head was patr worn, giving print quality below normal. It would have at least printed if the fault was just the head. I understand these bubble jet printers vaporise the in, so that would suggest a lack of power to this function. I will add that I am a retired TV engineer.
I already tried that till I was sick of it.
The second hand head was storred in its box. Could the machine with the cleaning gears fault have a good logic board? Can you describe its position in the printer and what it looks like.
OK, but please don't cause my bill to increase beyond what you have already charged me.
It seems the professional has left this conversation. This happens occasionally, and it's usually because the professional thinks that someone else might be a better match for your question. I've been working hard to find a new professional to assist you with your question, but sometimes finding the right professional can take a little longer than expected.
I wonder whether you're OK with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.
Thanks for your patience,
I will give it another day, but I feel the printer is not worth expensive prolonged investigation.
I am closing the computer now until tomorrow; bear in mind the time difference here in the UK.
We will continue to look for a Professional to assist you.
