Hello, I'm Nathan and I will be assisting you today. Please remember to rate/accept my answer when we have finished. Thank you.
Hi there, sorry to hear you're having trouble with the printer,
can you tell me what is happening now? Do you get an error message? Does it just not respond to print commands? Does it try to print but makes some clunking noises and won't move?
Okay, that unfortunately is a good indication of internal hardware damage,
meaning you may have broken something in the drive mechanism when you moved the printhead (damaged belt/gear/motor/sensor)
Can you try pushing the head back to where it was initially before you moved it
we'll then reset the printer:unplug power at the mains for at least an hourpress and hold the power button for 60+ seconds,keep holding while plugging power cord back in, and for another 60 seconds afterrelease button and check for functionality
if the problem still persists at that point, there unfortunately isn't much else to be done, repairs would be required at that point, which just wouldn't be practical for a 10 year old printer (even for a 2 year old printer), as you'd typically be looking at £250 for an average repair, while you can buy a brand new machine, with updated features and a fresh warranty, for 75-100.
thanks, let me know how it works out, when you have a chance.
And if it doesn't help, I'll be happy to help with recommendations for replacement models, if you'd like.
