Abstract

A printer configured to print on substrates that undesirably tend to collect debris before being printed, comprises a print station including a printhead, and a printer body configured to receive a replaceable cartridge that holds a printer consumable (such as a ribbon) and a substrate cleaning structure. The printer body is constructed and arranged so that when a cartridge is received in the body, the cleaning structure is operable to at least assist in removing debris from a substrate. The cleaning structure may comprise a tacky or sticky belt, web or roller. The cleaning structure may be configured to present a sticky surface to a primary cleaning member that engages and cleans the substrates. Alternatively, the cleaning structure may be configured to directly engage and clean the substrates. Preferably, the useful lives of the cleaning structure and the printer consumable are commensurate. Also disclosed is a replaceable cartridge that holds both a printer consumable and a substrate cleaning structure, the cartridge being configured so that when it is received in a printer it is operable to at least assist in removing debris from a substrate. Also disclosed are a method of cleaning an information-receiving surface of a substrate and a method of cleaning a substrate-cleaning member of a substrate printer.

Claims

1. A ribbon cartridge for printing on a succession of substrates proceeding along a substantially horizontal path, said ribbon cartridge comprising:

a ribbon supply spool holding a supply of printer ribbon;

a ribbon take-up spool configured to take-up a consumed portion of the supply of printer ribbon;

a consumable cleaning member having a useful life related to a useful life of the supply of printer ribbon;

a housing configured to support the ribbon supply spool in a fixed and elevated position relative to the ribbon take-up spool so as to define a substrate cleaning station cavity generally below the ribbon supply spool and above the substantially horizontal path, and wherein the housing is further configured to support the consumable cleaning member proximate the cleaning station cavity.

2. The ribbon cartridge of claim 1, wherein the ribbon cartridge further includes a supply spool enclosure, wherein the supply spool enclosure is in a fixed and elevated position relative to the substantially horizontal path.

3. The ribbon cartridge of claim 2, wherein the substrate cleaning station cavity is disposed substantially below the supply spool enclosure.

4. The ribbon cartridge of claim 3, wherein the consumable cleaning member defines a consumable cleaning member axis about which the consumable cleaning member rotates, and wherein the lowest portion of the supply spool enclosure is elevated relative to the consumable cleaning member axis.

5. The ribbon cartridge of claim 1, wherein the consumable cleaning member is structured to be driven upwardly into the cleaning station cavity when contacting a substrate proceeding along the substantially horizontal path.

6. The ribbon cartridge of claim 1, wherein the consumable cleaning member is spring biased toward the substantially horizontal path by at least one compression spring.

7. A ribbon cartridge of claim 1, wherein the housing defines first and second longitudinally oriented support plates, wherein the ribbon supply spool defines a supply rotational axis and the ribbon take-up spool defines a take-up rotational axis, wherein the supply rotational axis and the take-up rotational axis are positioned transversely relative to the first and second longitudinally oriented support plates, wherein a space is defined between the supply rotational axis, the take-up rotational axis, the first longitudinally oriented support plate, and the second longitudinally oriented support plate, and wherein the housing is structured to position the consumable cleaning member outside the space.

8. A ribbon cartridge for printing on a succession of substrates proceeding along a substantially horizontal path, said ribbon cartridge comprising:

a ribbon supply spool holding a supply of printer ribbon and having an axis of rotation, wherein the ribbon supply spool is substantially surrounded about the axis of rotation by a supply spool enclosure;

a ribbon take-up spool configured to take-up a consumed portion of the supply of printer ribbon;

a consumable cleaning member having a useful life related to a useful life of the supply of printer ribbon;

a housing configured to support the ribbon supply spool enclosure in a fixed and elevated position relative to the substantially horizontal path and configured to support the ribbon supply spool in a fixed and elevated position relative to the ribbon take-up spool; and

a cleaning cavity defined between the ribbon supply spool enclosure and the substantially horizontal path, wherein the cleaning cavity is configured to receive the consumable cleaning member.

9. The ribbon cartridge of claim 8, wherein the consumable cleaning member is disposed entirely below a lowest edge of the ribbon supply spool enclosure.
