If there is an item present, then the item indicates what is causing the print engine sub- system to be not ready. cDoorOpen is in the collection if one or more access panels are open. If the device contains more than one access panel, then NOT-READY- PRINT-ENGINE-DOOR indicates which access panel(s) are open. cInternalMediaJam is in the collection if one or more pieces of media are jammed inside the device. If the media is jammed at an input tray, cTrayMediaJam is in the collection, and if the device has more than one input tray, then NOT-READY-MEDIA-JAM-AT-TRAY indicates which tray has a media jam. If the media is jammed at an output bin, cBinMediaJam is in the collection, and if the device has more than one output bin, then NOT-READY- MEDIA-JAM-AT-BIN indicates which bin has a media jam. cRequestedMediaUnavailable is in the collection if the current print job requires media that is not available. cTrayEmpty is in the collection if the current print job requires media from an input tray that is empty. If the device has more than one input tray, then NOT-READY- TRAY-EMPTY indicates which tray is empty. cOutputBinFull is in the collection if an output bin is full. If the device has more than one output bin, then NOT-READY-BIN-FULL indicates which bin is full. cManualFeedMedia is in the collection if the device is waiting for media to manually be fed. cMarkingAgentMissing is in the collection if a marking agent (toner cartridge, ink pen, etc.) is missing. If the device has more than one marking agent, then NOT- READY-MARKING-AGENT-MISSING indicates which marking agent is missing. cMarkingAgentOut is in the collection if the device is not ready due to one or more marking agents being low or out. If the device has more than one marking agent, then NOT-READY-MARKING-AGENT-LOW-OR- OUT indicates which marking agent is low or out. cIncorrectMarkingAgent is in the collection if the device detects that an incorrect marking agent is installed. If the device has more than one marking agent, then NOT-READY-INCORRECT-MARKING-AGENT indicates which marking agent location is loaded with the wrong type of marking agent. cTrayMissing is in the collection if the device is not ready because one or more trays are not installed. If the device has more than one input tray, then NOT-READY-TRAY-MISSING indicates which tray is missing. cDeviceSpecific is in the collection if one or more items are in either NOT- READY-LASER-PRINT-ENGINE or NOT-READY-DESTINATION- INKJET-PRINT-ENGINE-NOT-READY. cMediaPickMisfeed is in the collection if the print engine detects the tray is not empty, but can not pick up a sheet of media from that tray. cMarkingAgentFailure indicates there is a failure with a marking agent and it may need to be replaced. If the device supports more than one marking agent, then the NOT-READY-MARKING-AGENT-FAILURE object indicates all the marking agents that have failed. The POS will indicate the marking agent failure recovery process, if any.
