When the printer requires service, operation stops and the message 
window displays CALL FOR SERVICE followed by the location of the 
problem and error number. Have this information available when you 
call for service.
Service calls should be placed to the vendor from whom you pur-
chased the printer. If you cannot get service from your vendor, see 
appendix A, “QMS Customer Support.” 
WAITING ON 
INPUT
END JOB?
The compiler is waiting on incoming 
data for the first job in the queue. The 
job may not have an end-of-job 
indicator and therefore cannot end. The 
message clears if more input arrives 
from the port or if you press the Cancel 
key. No other jobs can be printed until 
this job has ended.
WARMING UP The printer is warming up.
