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.
Likely your paper is loaded incorrectly or is incorrect for the unit. The auto print format depends on the position of the black "que" mark in the paper, but the manual mode does not. Be certain that the paper is correct for you unit. If that isn't it, then you que sensor could be dirty or defective. THis would require shop level repair, as dis-assembly of the unit is required.
Does it work in auto mode ? are you putting paper correctly means , there is a black mark on paper which is sensed by paper sensor .If you put paper up side down then paper sensor won't be able to sense any paper & gives you error for rifilling paper .If this doesn't help you then You need to replace battrey . Thanks
If it stops printing completely in the middle of doing the print, it is because the battery is bad and needs to be replaced. If it only prints some of the leads but it does print the full report it is because you have the leads mixed up (Wrong spot on the patient) or the leads are mislabeled or some of the clips or electrodes are bad. I can fix these. Let me know if you need help.
Hello medico001, The info on the Schiller web site states an option of 12 lead for model Cardivot AT. If your unit has this option only the automatic selection will deliver the 12 lead print. For futher info select the web site http://www.schilleramerica.com and click on 'Contact Us'. This should direct you to someone local. Good luck.
