Printer with secure tray

A printer, comprising:

• a secure tray fully inserted into the printer, the secure tray comprising a notch on a side of the secure tray;
• a printing mechanism configured to, upon receiving a print command, print on a sheet of paper picked from the secure tray;
• a latch assembly comprising a latch, the latch structured to have an extended position extending into the notch thereby locking the secure tray inside the printer and a retracted position not extending into the notch thereby enabling removal of the secure tray from the printer;
• a transceiver connected to a controller processor, the transceiver configured to receive wireless signals;
• the controller processor configured that upon receipt of a particular wireless command by the transceiver, causes the latch to retract into the retracted position from the extended position;
• and
• a left corner shield located at a left rear inside of the secure tray and a right corner shield located at a right rear inside of the secure tray.

A printer, comprising:

• a secure tray fully inserted into the printer, the secure tray comprising a notch on a side of the secure tray;
• a printing mechanism configured to, upon receiving a print command, print on a sheet of paper picked from the secure tray;
• a latch assembly comprising a latch, the latch structured to have an extended position extending into the notch thereby locking the secure tray inside the printer and a retracted position not extending into the notch thereby enabling removal of the secure tray from the printer;
• a transceiver connected to a controller processor, the transceiver configured to receive wireless signals;
• the controller processor configured that upon receipt of a particular wireless command by the transceiver, causes the latch to retract into the retracted position from the extended position;
• and
• a non-secure tray which has no locking mechanism and the printer is configured to enable printing from the non-secure tray when printing is prevented to the secure tray.

A printer, comprising:

• a secure tray fully inserted into the printer, the secure tray comprising a notch on a side of the secure tray;
• a printing mechanism configured to, upon receiving a print command, print on a sheet of paper picked from the secure tray;
• a latch assembly comprising a latch, the latch structured to have an extended position extending into the notch thereby locking the secure tray inside the printer and a retracted position not extending into the notch thereby enabling removal of the secure tray from the printer;
• a transceiver connected to a controller processor, the transceiver configured to receive wireless signals;
• and
• the controller processor configured that upon receipt of a particular wireless command by the transceiver, causes the latch to retract into the retracted position from the extended position,
• wherein the controller processor is connected to a paper pick actuator configured to enable and disable operation of a pickup roller for the secure tray, the controller processor configured to disable the pickup roller when the printer is in a first mode of operation, the controller processor configured to enable the pickup roller when the printer is in a second mode of operation.

A printer, comprising:

• a secure tray fully inserted into the printer, the secure tray incorporating a locking mechanism having a locked state preventing removal of the secure tray from the printer and an unlocked state enabling removal of the secure tray from the printer;
• a printing mechanism configured to, upon receiving a print command, print on a sheet of paper picked from the secure tray;
• a transceiver;
• a controller processor connected to the transceiver and the printing mechanism, the controller processor configured to read and execute computer readable instructions from a computer readable storage medium, the computer readable instructions programmed to cause the controller processor to:
• implement a refuse mode by default, the refuse mode preventing the printing mechanism from printing from the secure tray;
• change modes from the refuse mode to an accept mode when a particular wireless command is received, the accept mode enabling printing from the secure tray;
• and
• change modes from the accept mode to the refuse mode when a specific wireless command is received.

A method to convert a printer to a secure printer, comprising:

• providing the printer;
• installing a controller processor on the printer;
• removing at least one rail guide from the printer;
• installing at least one latch assembly in place of the at least one rail guide;
• connecting a latch assembly cable between the latch assembly and the controller processor;
• connecting a transceiver to the controller processor;
• and
• installing a secure tray which comprises a detectable object on a side of the secure tray.
