Abstract
An electro-photographic print system or method for regulating a supply of toner based on a required toner amount.
Claims20
An electro-photographic print system, comprising
- a toner reservoir,
- a toner supply roller assembly,
- a toner supply regulator regulating the supply of toner from the reservoir to the toner supply roller assembly, and
- a control circuit
- to calculate a toner amount required by the toner supply roller assembly, and
- to instruct the toner supply regulator to supply toner to the toner supply roller assembly based on the calculated required toner amount.
3 more elements
A method of printing, comprising
- measuring toner amounts,
- calculating a required toner amount,
- detecting a relatively high required toner amount,
- consequently printing while a toner supply regulator stimulates movement of toner out of a reservoir to a roller assembly,
- detecting a relatively low required toner amount, and
- consequently printing while the toner supply regulator inhibits movement of toner in the reservoir.
