Questions about this item

Will the printhead on this board need periodic cleaning or eventual replacement?

The board is a printhead assembly; nozzles clog over time so regular cleaning cycles are required and the head itself must be replaced when output degrades.

What limit appears first during continuous printing with this board?

Sustained use heats the printhead nozzles, triggering thermal protection that pauses the job until the assembly cools.
