self-test

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.  
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 some internal testing, 
the page to be formatted and put in the printer's 
print queue. Before the page is in the print queue, a 
get on this object will return eNonDestructiveSelfTest 
Attempting to set this object before the page has 
completed being formatted and printed will cause 
<genErr> status to be 
returned with a value of eNotInASelfTest.  
After the page is in the queue, a get on this object 
will return a value of eNotInASelfTest. 
Setting this object to eNonDestructiveSelfTest 
before the first page has completed results in 
a status of <genErr> status 
with a value of eNotInASelfTest.  
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.
