Hi Everybody, We recently had a new rack addition installed in our 3494 library this Sunday. Since that was done, we have been getting about 75 scratch tapes since Monday being changed from scratch to a private state because of errors reading the label. I've checked about 30 of these tapes and they look fine. Has anyone run into this problem ? Could it be an alignment issue with the gripper ? Rich
Richard - I presume that this was a frame install, and is a barcode reading issue rather than success in picking, mounting, but media label reading issue. Barcode reading issues can result from failing to do a full Teach on the frame so that the accessor understands positioning therein, or (unlikely) a cell matrix has shifted since the install. The CE can inspect the 3494 logs to see what the issue is. I would verify conditions by first going to the 3494 LCD panel and checking that tapes known to be in that area are properly cataloged as such in the LM database. (Look for any anomalies in what it shows, relative to other tapes in other frames.) If the accessor will enter the new frame area, incite an attempt to mount a tape while you watch, and see if the laser scans the barcode region properly, compared with scanning barcodes in the more visible frame 1, for example.
