Go over them with the dna again! And again... and again...
OK, folks, any suggestions?
In the meantime I return my focus to the poorly functioning carriage.
On closer inspection it looks as though the carriage strap is intact and connected to both ends.
Although it does look a bit frayed on the edges towards the middle.
Is it possible that the loose threads could be hindering the movement of the carriage?
This makes me suspect that it is the spring and not the strap that is causing the problem.
Does this mean I will have to remove the platen to access the carriage spring?
I have no idea.
Stay tuned, friends.
