All devices whether completely unpackaged as outlined in the New Device Install testing or stretch wrapped to a pallet as outlined in the Hardware Return or Relocation testing are placed on the vibration table without restraint. Four column stacking fixtures are placed on the table in order to keep the product from falling off, but not placed tight to the product, see figure 3. Shock Test: The shock test is used for New Device Install on units without caster bases and Hardware Return or Relocation testing. Hardware Return or Relocation the palletized printers receive bottom drops from 4 inches a total of 6 times. For the New Device Install the shock testing involves a series of rotational edge drops onto concrete without packaging. During the first series of drops an 80mm height block is placed under a side bottom edge of the printer and pulled out, this test is based on ASTM D 6179 – 07, allowing the printer to impact the concrete on the raised edge. All four bottom edges are tested. The second series of drops use the 80mm height block along with a 40mm height block. The blocks are placed on opposite bottom edges and removed simultaneously allowing for a multiple impact drop onto the concrete. All four bottom edges are tested. MFP Lift Test: The MFP lift test is conducted only on New Device Install testing of printers that are MFP's and that do not have caster bases. This test is part of the Product Assurance testing and was incorporated into this test specification as it represents how MFP's are handled during the unboxing process and prior to its final usage location. Due to the location and shape of scanners they can be mistaken as grip areas, especially if the proper grip areas are not easily identifiable. This handling can lead to scan defects. The testing is conducted by lifting the printer off the floor using the scanner and traveling a distance of 2 meters. MFP Lean Test: The MFP lean test is conducted only on New Device Install testing of printers that are MFP's on caster bases. This test is currently included in the procedure but yet to be fully defined. It will involve leveraged tilt of the MFP on casters which puts force onto one or two wheels only. For MFP's on casters this testing takes the place of the MFP Lift Test, as these products are too large to be carried by the scanner. Carpet Course: The carpet course test is conducted only on New Device Install testing of printers that have caster bases. Currently this portion of the test is included as most office environments where large printers on casters are placed have low pile carpet. This testing category is included but has yet to be fully defined.
