A field service engineer (fse) went to the customer site to evaluate the problem and perform preventive maintenance (pm) on the g8 analyzer.Following, the fse performed calibration, ran quality controls and did precision testing on the g8 analyzer.Operation of the g8 analyzer was verified and placed back into use.Per the service report no large syringe error code occurred.It is believed that the sampling needle was clogged which prevented the syringe from pushing fluid out of the needle.Replacing of the clogged needle with a new one, the system was able to flush through the needle as expected.The most probable cause of the reported event is related to clogging of the specimen nozzle.Review of the g8 variant analysis operator's manual indicates the error message "706 syringe-l error is an operation error in syringe-l.Counter measure: inspect syringe-l.Execute smp.Reset.Error level 2: enter wash state.Alarm level 1: beep for 30 sec and turn on error led & patolight® (optional).Review of the tosoh automated glycohemoglobin analyzer g8 service manual for 706 syringe-l error addresses the following information: content: operation error in syringe-l monitoring method: unexpected home sensor and limiter sensor signals are monitored during syringe l operation cause: a) incorrect syringe l operation b) syl motor fault c) syl-u sensor fault d) syl-d sensor fault e) drv2 board fault f) asm board fault countermeasure: a) inspect syringe l b) inspect the syl motor c) inspect sensors d) inspect boards.(b)(4).This report is being submitted due to a retrospective review conducted under capa-(b)(4).
