Thank you for the info, and my apologies for the delay. The site is not quite instant, but please try to send only a single response and allow me time to receive it and respond back; multiple messages can get lost in the queue and further delayed.
To be clear, the fee was never only $5.
We are all licensed experts here, and we charge a fair price for service. 5$ is not the price, only the initial deposit, you agreed to the full amount on the payment page. Rationally you can’t expect highly trained and licensed service professionals to work for $5 or less.
There are a few possible causes of this issue, including a bad cartridge, internal debris/contamination, or a hardware failure (bad printhead, bad logic board, faulty sensor, etc).
What we can try are some cleaning and reset steps.
First remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.
Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release
Let me know the results, and I'll advise further if needed.
