self-test 1.3.6.1.4.1.11.2.3.9.4.2.1.1.5.1

Writing this object allows a device self test to be started. Reading this object provides an indication what self-test is currently executing, if any. Actual self-test operation is device specific. A self test may not be allowed at any arbitrary time. If the device supports the requested self test, but can not start the execution of the self test when requested, the device will respond with <genErr>. If a non-destructive self test is being started, the device will generate a response before the self test is completed. RECOMMENDATION: If the device is ready (i.e. the NOT- READY-PRINTER object does not contain any items, except maybe being off-line) and is idle (i.e. the NOT-IDLE object does not contain any items), this request should always succeed. This provides a mechanism for driver writers to always determine if the action will succeed or not. Additional information: The eNonDestructiveSelfTest performs limited testing on the printer and its attached paper handling devices. After the self-test is complete a configuration page is printed. The recommended way to cause a configuration page to be printed is to use the PRINT-INTERNAL-PAGE object. A continuous self test cannot be started or terminated using this OID. The printer must be idle before it can execute a self test. The best method to assure that the printer is idle is to set the object ON-OFF-LINE to eOfflineAtEndOfJob, wait for the printer to be offline and then execute the self test. The printer will put itself online to print the page. When the printer is idle, setting this object to eNonDestructiveSelfTest results in a status of <noError> and a value of eNonDestructiveSelfTest being returned. If the printer is not idle (whether printing an external job, printing an internal page or running self test), a status of <genErr> status will be returned with a value of eNotInASelfTest. When the printer is idle, setting this object to eNonDestructiveSelfTest causes the page to be formatted and put in the printer's print queue. Before the page is in the print queue (which could take several seconds), a get on this object will return NonDestructiveSelfTest. After the page is in the queue, a get on this object will return a value of eNotInASelfTest. Attempting to set this object before the page has completed printing will cause <genErr> status to be returned. In this case the value will either be eNonDestructiveSelfTest if the page has not been queued or eNotInASelfTest if it has been queued. Likewise, if the PRINT-INTERNAL-PAGE object is set to a valid value and that page has not printed when this object is set to eNonDestructiveSelfTest, a status of <genErr> status with a value of eNotInASelfTest will be returned until the internal page has printed.
