Dear Sirs,
We have a AM-4290 urine analyzer which cannot print out the result and only return ready state after the machine doing a measurment.We act a" print one" from menu,it only print out a historic result long time ago.We also cleaned the white base and light.

We will be grateful if we can receive your reply!
