national center for remanufacturing and resource recovery toner cartridge evaluation results summary results the page yield of the premium imaging products sample cartridge of 10,423 was 104 of the oem stated yield of 10,000 pages the sample cartridge produced clean crisp clear text and lines also it consistently exhibited a maximum density performance above 1.4 throughout the life of the cartridge no toner leakage was observed in the cartridge packing material or during operation of the cartridge in the printer the premium imaging products sample cartridge produced no detrimental effects on the test printer total pages per astm 1856 5 coverage 20000 17500 15000 12500 10000 7500 5000 2500 0 03-231a 03-231b 140 120 100 80 60 40 percent of stated yield 03-231a 03-231b a major portion of the total cost of ownership for a remanufactured cartridge can be measured as the cost per print in the shaded areas below fill in your current selling price and then divide it by the yield fill in the re

national center for remanufacturing and resource recovery toner cartridge evaluation results average maximum density the maximum density for a print may be simply described as a measure of `blackness an image quality test target was run at the start of testing and at every 1000 pages density measurements were made on the one inch square solid area blocks located at the center of the page and in the four corners the threshold limit is the minimum density value the block could have and maintain an acceptable appearance maximum density values below this threshold would appear as voids within the block and would be considered unacceptable by the average customer average solid area density 1.80 1.70 1.60 1.50 1.40 1.30 1.20 1.10 1.00 20 2500 3500 5000 print count density 03-231a 03-231b threshold min 6000 7500 8500 average background density background can be characterized as small randomly distributed spots in non-image background areas on a print an image quality test target was run at t

national center for remanufacturing and resource recovery toner cartridge evaluation results the statistical process control chart represents the oem cartridges that have been evaluated to date at ncr3 using the astm f1856 process for the specific cartridge model submitted for analysis if the cartridge did not fall within these control limits ncr3 can help determine the root cause of the shortfall whether the cartridge was under the lower control limit lcl or above the upper control limit ucl there is a cost of non-conformance associated with each if the ucl is exceeded there may be an opportunity to maximize profits if the lcl is exceeded there is the cost of possible customer dissatisfaction the toner transfer charts below indicate how much toner is transferring to the print media ncr3 s imaging products laboratory is equipped with the latest equipment to analyze toner opc s magnetic rollers and pcr s chart not available the cartridge toner transfer charts illustrate the efficiency

national center for remanufacturing and resource recovery toner cartridge evaluation results the evaluation of all-in-one laser printer toner cartridges summary the ncr3 evaluation process is based upon a series of integrated standardized tests primarily astm f1856 and the stmc guide for toner cartridge evaluation to provide an evaluation of all-in-one laser printer toner cartridges for cartridge yield image quality and cartridge integrity overall approach the initial step is to establish a baseline performance by using a series of integrated standardized tests to evaluate the performance of a selected control toner cartridge designated cartridge a then identical tests are performed on the cartridges of interest cartridge b using the same printer the performance of the cartridge b is compared to that of control cartridge a image quality a suite of 5 iq test are run at the beginning of testing and at approximately 1000 page intervals thereafter density and background measurements

national center for remanufacturing and resource recovery toner cartridge evaluation results cartridge yield depending on cartridge size one to three 1000-print runs are made using a specified 5 output test target by weighing the supply hopper before and after each run the toner consumption per page is determined for each 1000-print test interval at the outset of evaluating the cartridge the toner supply hopper assembly is separated from the cartridge and weighed when a cartridge has printed approximately 80 of its advertised yield printing is stopped the cartridge is disassembled any toner in the supply hopper is removed and the empty hopper is weighed by subtracting the empty hopper weight from the full hopper weight the initial toner load is determined by dividing the initial toner load by the average consumption rate of the yield runs the cartridge print yield is calculated this approach eliminates the subjective judgment of print fade and the variation procedures employ to estab
