ACARD DVD DUPLICATOR *

THIS IS FOR A ACARD DVD DUPLICATOR, I BOUGHT THIS SECOND HAND, IT WORKS NO PROBLEM WHEN COPYING ON A ONE TO ONE BASIS BUT IS TEMPERAMENTAL WHEN ASK TO COPY MORE THAN ONE DISC, SOMEONE WITH A PC KNOWLEDGE MAY BE ABLE TO FIX, i HAVE HAD THE UNIT FOR 6 MONTHS AND PREVIOUS OWNER SAID HE HAD FOR 18 MONTHS, IT IS A 1 TO 7 COPIER BUT HAS A DRIVE MISSING, SO YOU HAVE ONE MASTER DRIVE AND SIX YOU CAN COPY TO, CAN BE SEEN WORKING ON A ONE TO ONE BASIS, BUT AS I SAID ASK TO COPY MORE THAN ONE DISC YOU PROBABLY WILL GET ERRORS, BUT THINK IT IS REPAIRABALE, COMES WITH POWER LEAD, AND DOES NOT NEED PC TO RUN, STAND ALONE UNIT
