Description: This object represents any error conditions detected by the printer. The error conditions are encoded as bits in an octet string, with the following definitions: Condition Bit # hrDeviceStatus lowPaper 0 warning(3) noPaper 1 down(5) lowToner 2 warning(3) noToner 3 down(5) doorOpen 4 down(5) jammed 5 down(5) offline 6 down(5) serviceRequested 7 warning(3) If multiple conditions are currently detected and the hrDeviceStatus would not otherwise be unknown(1) or testing(4), the hrDeviceStatus shall correspond to the worst state of those indicated, where down(5) is worse than warning(3) which is worse than running(2). Bits are numbered starting with the most significant bit of the first byte being bit 0, the least significant bit of the first byte being bit 7, the most significant bit of the second byte being bit 8, and so on. A one bit encodes that the condition was detected, while a zero bit encodes that the condition was not detected. This object is useful for alerting an operator to specific warning or error conditions that may occur, especially those requiring human intervention. Refer to RFC 1514, Host Resources MIB, for more details. Additional information: LaserJet 9000mfp reports error conditions as follows:

lowPaper -- A tray is empty, but the media to be loaded is not currently needed. hrDeviceStatus = eHwarning; hrPrinterStatus = eHidle or eHprinting; A non-critical alert is active.

noPaper -- A tray is empty and must be filled for printing to continue. hrDeviceStatus = eHdown; hrPrinterStatus = eHother; A critical alert is active.

lowToner -- Toner is almost gone. The quality of printed pages will begin to deteriorate until the toner is completely gone. hrDeviceStatus = eHwarning; hrPrinterStatus = eHidle or eHprinting; A non-critical alert is active.

noToner -- LaserJet 9000mfp printers do not report this condition.

coverOpen -- A printer cover or door is open. hrDeviceStatus = eHdown; hrPrinterStatus = eHother; A critical alert is active.

jammed -- Paper is jammed and the printer will be unable to continue printing until the jam is cleared. hrDeviceStatus = eHdown; hrPrinterStatus = eHother; A critical alert is active.

offline -- Printer is offline and will not accept new print jobs until it is online again. hrDeviceStatus = eHdown; hrPrinterStatus = eHother; A critical alert is active.

serviceRequested -- Any status or error condition not listed above. If the condition prevents printing, the 'offline' bit is also set and the hrDeviceStatus and hrPrinterStatus listed for offline above are returned. hrDeviceStatus = eHwarning; hrPrinterStatus = eHidle or eHprinting; A non-critical alert is active.
