91th day of attachment
An ECG recorder, Schiller AT-2 Plus which was brought down by my colleague and me from ward 3 a few days ago and I did mention that the fault is the printing keep stopping and it is not due to paper jam. I analyzed the fault by going to ward 1 where they have the identical Schiller ECG recorder with the paper feed from the faulty one. After exchanging the paper feed, ECG recorder which from ward 1 still able to generate the ECG. When I removed the paper feed, I found that the print head not came out of the printer. After I screwed back the print head into the printer, the paper still jam. Therefore, I took the service manual to seek any stated possible problems.
The problem was the catch on the printer paper tray has worn out and the springs exerting too much pressure that the paper tray lid either could not be pushed in or using more strength to push the tray back in. The problem was found with the help of my colleague. The tension is achieved with two springs exerting certain amount of pressure on the print head. Since the catch are worn out, the paper tray lid unable to closed tight as the springs keep pushing the worn-out catch away from the paper tray. The solution is to cut a bit of the spring on one of the side of the paper tray. The paper able to print 3 out of 6 waveforms as the the paper tray did not place nicely or the alignment of the print head is incorrect. Therefore, we tried slotted the paper tray lid tightly to the paper tray and the ECG recorder able to print the full 6 waveforms without patient informations or 4 waveforms with patient's informations.
My colleague and I tried to finish the preventive maintenance for the remaining equipments as we only have a week to complete the maintenance. Some of them are not located as the end-users may transfer to different wards.
In the afternoon, I helped out my administrative colleague to print out the work flow for tomorrow's exercise that were be carried out at 19 locations nationwide. Most of the Hospitals, some secondary schools, Changi Airport Terminal 2 and etc are involved for this exercise. Print-outs are given to 37 departments. Print-outs which contents about how to handle any suspected case.
