During a retest of the Xerox 5665, this versatile, easy-to-use unit displayed improved reliability over its previous extended-term test. Due to reliability problems experienced by BLI with the first Xerox 5665 test unit, which resulted in the unit receiving a "Not Recommended" rating, a second test unit was installed in the lab and was required to run beyond the normal testing period to verify the unit's overall reliability. According to documentation provided by Xerox, the second test unit incorporates certain field service fixes and improvements (these fixes and improvements were cut into production units as of April 10, 1998, according to Xerox).
During the four-month retest period, 500,000 impressions were produced on the Xerox 5665, during which the unit, as it had done in the previous testing on this model, once again displayed excellent versatility and superior ease of use. Moreover, the reliability of the Xerox 5665 improved when compared with the results from the extended-term test on the original test unit. Three service calls were required in the retest period, translating to MCBS/MCBF (Mean Copies Between Service/Mean Copies Between Failures) rates of 166,667 impressions. And although the second test unit misfed 17 times, for an overall misfeed rate of one per 29,412 impressions, which is worse than that for the original unit tested, the misfeeding, which was mostly in the stapler sorter area, was isolated to the first 195,329 copies of the test. After the second service call for misfeeding in the stapler sorter, which occurred at 195,329, only three …
