Why do the printer cartridges move from right to left when you switch on the printer?
In: Technology
The printer wants to know where its cartridge is, so it knows where to start printing from. If you pulled the plug mid-print last time, the cartridge would be abandoned half-way across the carriage. If it just started printing from there, where you think the top left bit of image is, would instead start being printed in the top middle of the page.
So the printer moves its cartridges and finds where the zero-point is and does some other self-checks to make sure things are moving as they should.
It’s a check-up of printing system. The printer check If there are any problema with motors and other stuffs.
The printer is checking that the carriage is operating properly then “homing” it (setting it to a known zero reference point).
