The test sheets are filled from the top to a maximum height of 660 mm. This corresponds to approximately 6,600 sheets of copying paper. A stack of test sheets can consist of several different types of paper. When a sheet with a barcode is found in the stack (a barcode reader is included in the sheet feeder), this indicates that this is the first sheet in the series. Sheets below this sheet are regarded as belonging to the same series until the next barcode is detected. The operator can produce new barcodes by specifying identity and measurement programme.  The code is printed in the barcode printer included in the delivery.

The recommended sheet size is for A3 sheets (297 x 420 mm – 11.7 x 16.5 in). If all measurement cannot be carried out, e.g. due to too many destructive measurements, an additional series of sheets should be prepared and measurements on these should be carried out.

Sheet measurement is easy to cancel in order to measure profile strips instead. A special roller holder for profile strips is placed above the sheet feed table to facilitate this measurement.
