HI, Its a common problem with Schiller ECG machine. The battery of your ECG machine is faulty. Even if you are using the machine in AC it uses the battery power. The AC power is only used for charging the battery.
When the machine starts to print the battery will drop down and the printing will stop. This is happening with the machine. It will eject the first paper without printing. its normal. Because the machine starts printing on a fresh page only. In your case the machine is ejecting the first paper. When the machine starts its printing in the second page it will draw a large amount of current from the battery for its thermal printing head. If the battery is not proper then it will suddenly drop the printing. The square box you see is not printed by your ECG machine. Its already printed in the paper of Schiller. With this mark the Machine sense the page.
Its a 12 volt 2.3 AH battery. You will not be able to replace the battery from out side any where. For replacing the same you have to open the machine by removing the screws on its bottom. Be care full with the paper tray while removing the top cover. Also do not use any force to open the top cover because there are connections on the top cover. Here i have added a link to the battery for Schiller AT2 PLUS
The Schiller AT1 is a battery powered unit. A common symptom of weak/defective battery's is that it will stop printing after 1-2 seconds of run. As to whether the patient cable effects this, I honestly don't know, It really shouldn't, baring some very weird internal short in the cable. The battery in the AT1 is beyond the average user to safely replace. Before anything else insure that the AC indicator light illuminates when the unit is plugged in. If not, you device might have a defective power supply. In either case, the unit needs repair in a Qualified shop.
HI, check the paper u have inserted. it should be Schiller original paper with page marking. also clean the paper sensor. u can see the paper sensor near the side of printing head. a small square portion. clean it with an ear bud, don't use any solution for cleaning only ear bud. ok
Hello LV792727, Disconnect the AC & battery power and proceed with caution. Open the case to aquire access to the thermal print head. Clean the print head with a white eraser, the type used for cleaning ink prints not the #2 pencile eraser. Test the printing function. If necessariy use a Q-Tip with a light touch of Aceatone to whip the print head. The next step is replacing the printing element. Please inform me of the results. Good luck.
