Media detection

Media detection refers to two actions that Ricoh ProcessDirector must take when it sends jobs to cut sheet printers: determining what media a job should be printed on and determining what media is loaded in a printer. When Ricoh ProcessDirector establishes that information, it can schedule jobs correctly.

Ricoh ProcessDirector uses media objects to detect and match media. Like printer objects, media objects are representations of physical objects outside of the system. Each media object represents a type of paper, transparency, or other substance that your printers can print on. You can define media objects for each type of media that you use in your environment. Ricoh ProcessDirector uses those media objects to map the media requested by a job with the physical media that is loaded in the printer.

When a job is submitted with a job ticket, the job ticket usually includes information about the media that the job should be printed on. That information can include the name of the requested media, as well as properties of the media, such as size and color. The media detection setting determines how the system interprets that information to set the Media property for the job.

The media detection setting also affects how the Media ready property for a printer is set. If a printer supports SNMP or JMF, it can send information about the media loaded in its trays to Ricoh ProcessDirector. The system compares that information with existing media objects to find one that matches. When it finds a match, the name of the matching media object is used for the value of the Media ready property. If none of the existing media objects match, Ricoh ProcessDirector creates a new one with the specified values and uses its name as the value of the Media ready property.

Ricoh ProcessDirector provides two options for media detection:

  • Automated
    This option uses one or more media properties specified in the job ticket to determine the value of the Media property for the job. Ricoh ProcessDirector evaluates the property values in the job ticket and finds a media object with the same values. The name of the matching media object is stored as the value of the Media property.

    If more than one media object matches the specified properties, Ricoh ProcessDirector uses additional logic to choose the most appropriate value.

    In addition, this option lets Ricoh ProcessDirector use SNMP or JMF to set the Media ready property for printers based on the properties of the media, and create media objects if needed.

  • Manual
    This option uses the name of the media specified in the job ticket as the value of the Media property for a job, without checking any other media properties.

    You must use the Update media action on the printer object to specify the media loaded in the printer.

    If your printers do not support SNMP or JMF, you must use the manual setting.

When the Media property for a job and the Media ready property for printers are set, Ricoh ProcessDirector can use its regular scheduling process to send a job to the appropriate printer.
