Dual side printing with one print head
An automatic transaction machine (ATM) prints on both sides of a document having a first side and a second side. A printer rotates about a printer axis allowing the printer to move between a first positon and a second position. A transport moves a document adjacent the printer in the first position. While in the first position the printer is configured to print on a first side of the document as the document passes the printer on the transport. A document spool with a spool axis receives the document from the transport and at least partially rotates the document so the first side of the document is facing toward the spool axis. The printer rotates about the printer axis to the second position to print on the second side of the document that is facing outward away from the spool axis.
1. An escrow printer subassembly for an automatic transaction machine (ATM) configured to print on both sides of a document having a first side and a second side, the printer subassembly comprising:
a printer configured to rotate about a printer axis allowing the printer to move between a first position and a second position that is different than the first position;
a middle tape wheel,
a tape feed wheel to feed tape to and from the middle tape wheel,
a documents spool receiving tape from the middle tape wheel, and
a transport configured to transport a document adjacent the printer and to the tape extending between the middle tape wheel and the documents spool,
wherein while in the first position the printer is configured to print on a first side of the document as the document passes the printer from the transport, and wherein the printer is configured to rotate to the second position to print on the second side of the document when the document is on the documents spool, and wherein the documents spool is used as a backing surface for the printer to print directly on the document.
2. The printer subassembly of claim 1 wherein the documents spool is configured to rotate the document between 180 and 360 degrees after receiving the document from the transport and before the printer prints on the second side of the document.
3. The printer subassembly of claim 1 wherein the documents spool is generally cylindrical in shape and-rotates in a direction to receive the document and rotates in an other direction to remove the document.
4. The printer subassembly of claim 3 wherein the tape includes a plurality of layers configured to be wound onto the documents spool to hold a plurality of documents on the documents spool.
5. The printer subassembly of claim 1 wherein the first position is generally horizontal and the second position is generally vertical.
6. The printer subassembly of claim 1 wherein the printer is an ink-jet printer.
7. The printer subassembly of claim 1 further comprising:
a stationary scrapper configured to wipe ink from the printer when the printer moves between the first position and the second position.
8. The printer subassembly of claim 1 wherein the printer further comprises:
an ink cartridge re-movably attached to the printer.
9. The printer subassembly of claim 8 further comprising:
a transport guide including an ink scraper configured to wipe ink from an ink-jet nozzle in the ink cartridge when the printer moves between the first position and the second position.
10. The printer subassembly of claim 1 further comprising:
a sensor configured to detect when an edge of a document is approaching the printer.
11. The printer subassembly of claim 1 further comprising:
an electric motor configured to move the printer between the first position and the second position.
12. The printer subassembly of claim 1 wherein the document is a banking check and the printer is configured to print information on the check associated with depositing the check.
13. The printer subassembly of claim 1 wherein the transport is configured to transport the document vertically.
14. The printer subassembly of claim 1 wherein the printer rotates between 25 degrees and 120 degrees between the first position and the second position.
15. A deposit accepting apparatus configured to receive a document comprising:
a printer having a printing direction;
a printer support configured to support the printer and configured to move between a first position and a second position, wherein a printing direction of the second position is between 45 degrees and 120 degrees different than a printing direction of the first position,
a middle tape wheel,
a tape feed wheel to feed tape to and from the middle tape wheel, and
a documents spool receiving tape from the middle tape wheel, and
wherein the printer is configured to print on a first side of the document in the first position proximate the middle tape wheel and a second side of the document in the second position on the documents spool, and wherein the documents spool is used as a backing surface for the printer to print directly on the document.
16. The deposit accepting apparatus of claim 15 further comprising:
a transport guide proximate the middle tape wheel to assist transitioning the document between the tape and a document transport.
17. The deposit accepting apparatus of claim 16 wherein the document is held onto the documents spool by wrapping at least some of the tape around the documents spool.
18. The deposit accepting apparatus of claim 16 wherein the transport guide further includes:
a fixed non-movable scrapper configured to scape ink from a print head of the printer when then printer moves between the first position and the second position.
19. A method of operating a printer in an ATM comprising:
receiving a document from a transport at tape feed to and from a middle tape wheel by a tape feed wheel;
printing on a front side of a document when the documents is proximate the middle tape wheel and when the printer is in a first position;
moving the document with the tape from the middle tape wheel to a document spool;
moving the printer to a second position;
printing on a back side of the document when the document is on the document spool and when the printer is in the second position, wherein the first position is different than the second position, and wherein the document spool is used as a backing surface for the printer to print directly on the document.
20. The method of claim 19 wherein the moving further comprises:
rotating the printer about an axis from the first position to the second position.
