Summary of Test Method4.1 The test method consists of two procedures for deter-mining the productivity of an electrostatic copy machine whenusing any combination of accessories or attach
8、ments.4.1.1 Procedure A, Test Method For Measuring MachineProductivity, is a series of direct measurements of the timerequired to do specific numbers of copies under given circum-stances with selected accessories. It is intended to be quick andmachine dependent.4.1.2 Procedure B, Test Method For Mea
9、suring Job Produc-tivity, is a series of measurements of the various tasks andoperations on a copy machine. It uses standard jobs, and arrivesat overall productivity ratings which are both machine andoperator dependent.5. Significance and Use5.1 This test method is used to determine the copy perminu
10、te rating (productivity) of electrostatic copiers understandard conditions. It measures the time required to copy aspecific standard load on a copy machine. This productivityvalue is to be compared to the repeat copy rate for the samemachine to see if there is a change in the efficiency of themachin
11、e when various accessories or combinations of acces-sories are added to or used on the machine, or when the workload changes. It can also be used to compare the efficiencies ofdifferent but similarly equipped copy machines. It is suitablefor productivity evaluation by the user, and in research andde
12、velopment.6. Interferences6.1 The productivity of a copier can be affected by theattachment of an accessory whether it is operating or not. Thus,for a full comparison of the efficiency of a machine, it shouldbe tested with a given accessory removed, with it attached butnot operating, and with it att
13、ached and operating. If two ormore copiers are being tested and compared, it is important tomaintain as equitable a situation as possible, with attachmentson all machines being used in the same state.6.2 Productivity can be affected by the paper input sourceselection and similar nuances in operation

17、y the ability of the operator. Therefore it is importantthat the test operator be as familiar with the test machine as theaverage operator in the field would be. For this test, theoperator should have read the operators manual thoroughly,and have operated the test machine several times before theact
18、ual test. If operator proficiency cannot be satisfactorilyachieved, the time extensions induced by operator activitiesmay be excluded from the calculations. However this should benoted in the report.6.4 This test method addresses only the measurement of thetime needed for the copy machine to operate
19、. If office produc-tivity is to be measured, several other factors such as servicetime, supply availability, queuing time, etc., must be consid-ered. They are beyond the scope of this test method.6.5 In both test methods the number of copies to be made,the number of originals to be used and the numb
20、er of runs tobe made were selected to fit as typical a set of cases as possible.However for a given situation restricting the measurement tothese values may not be adequate. Therefore the user of thismethod is advised to use values for number of copies, numberof originals, number of runs and other p
21、arameters so that thesituation is adequately covered and a fair equitable comparisoncan be made.7. Apparatus7.1 Copy Machine to be tested with instruction manualsand specification sheets.7.2 Standard Test Load, Test Originals, a set of 8.5 by 11 in.originals. The number of sheets depends on the test
22、 beingperformed. The sheets should be reasonably flat, free from curl,unwrinkled, and neither crushed nor torn. A20 lb basis weight(17 in. by 22 in. 500 sheet ream) is preferred.7.3 Stopwatch or Timer, accurate to 0.1 s.7.4 Clock or Second Timer with a second hand.7.5 Supplies for the copy machine w
23、hich meet the copymachine manufacturers specifications.8. Conditioning8.1 The test area shall be the normal office environment,within the temperature and humidity range recommended bythe copier manufacturer for normal use.8.2 All supplies and the standard test loads shall be in thesame room as the t
24、est machine for at least 24 h prior to the testso that the temperature and moisture content of the supplieswill have stabilized. Supplies should be kept in their normalwrappers or storage containers until needed.9. Procedure AMethod For Measuring MachineProductivity9.1 Prepare the test machine for o
25、peration in accordancewith the manufacturers instructions. Run the machine to seethat it is operating properly. Determine the proper settings forthe test so that the images will be of proper quality and allaccessories are functioning properly. If necessary, have thecopier serviced to avoid any probl
26、ems.9.2 Preparing the OriginalsAny typing typical of theoffice work environment may be used as an original for thesetests, however the 4 % “k” chart in Fig. 1 of Test Method F 995is recommended. Two sets of originals are needed. One set willconsist of ten copies of the 4 %“ k” chart or other origina
27、l.These are to be on one side of the sheet of paper, and will beused for most of the tests. Make a second set of originals withthe pattern on both sides of the sheet of paper. This second setshould consist of five sheets of paper with the pattern on bothsides of the paper so that there are ten patte
28、rns on five sheetsof paper. The second set is for some of the duplexing tests.Number the individual “k” charts so that the copies can beuniquely identified. If extensive testing is to be done, severalsets of originals may be needed so that good, clean, flat,unwrinkled, and uncreased originals are al
29、ways used.9.3 Machine repeat copy rate:9.3.1 Measure the machine repeat copy rate. This is thenumber of 8.5 by 11 in. copies the machine can produce in 1min from the same original after the first copy has been made.All accessories are off, and all paper is fed from the defaultsource and is in the de
30、fault orientation. If the default trayallows for feeding of the paper in either the short or longdirection, load the paper or set the machine so that in default itfeeds in the short direction. Note the feed direction.9.3.2 Place a copy of the “k” chart on the platen of thecopier. Check to see that t
31、he copier is turned on and ready tooperate. Run one copy. Set the copier to produce eleven copies.Press the start button. When the trailing edge of the first copyexits the machine, start the stopwatch. When the trailing edgeof the eleventh copy exits the machine stop the stopwatch.9.4 First Copy Tim
32、e:9.4.1 Measure the first copy time. This is the time the copieruses to produce one copy from one original.9.4.2 Set the copier paper feed as described in 9.3.1. Placeone original on the platen. Set the selector to make one copy ofthe original.9.4.3 Simultaneously start the stopwatch and press the s
33、tartbutton on the copier. Stop the stopwatch when the trailing edgeof the copy exits the machine. Check the printed copy to seethat the copy is properly made and is of good quality. If therehas been a discrepancy, a blank sheet is found, or a jamoccurred, make note of this and then redo the test. Th
34、e latterresult will be considered valid.9.5 Copy Rate in the Simplex Mode:NOTE 1To measure the copy rate in the simplex mode the copier mustbe equipped with a feeder. If the test copier is not so equipped, go to 9.6.9.5.1 Measure the copy rate in the simplex mode. This is thenumber of copies per min
35、ute that the copier can make for agiven number of originals with a given number of copies fromeach original. Because the rate will depend on the load, a set ofthree values will be calculated. The series will consist ofmaking one copy each of ten originals, three copies each of tenoriginals, and five
36、 copies each of ten originals.9.5.2 Set the copier paper feed as described in 9.3.1. Placethe first set of originals (the single-sided ones) in the feeder. Setthe selector to make one copy per original.9.5.3 Simultaneously start the stopwatch and press the startbutton on the copier. Stop the stopwat
37、ch when the “ready forF 1318 90 (2003)2copying” prompt or indicator comes on. (If there is no readyindicator per se, stop the watch when the last copy drops intothe out tray, when the last original is ejected from the feeder, orother appropriate time.) Check the printed copies to see that allcopies
38、were properly made and are of good quality. If there hasbeen a discrepancy, a blank sheet is found or a jam occurred,make note of this and then redo the test. The latter result willbe considered valid.9.5.4 Set the copier paper feed as described in 9.3.1. Placethe first set of originals (the single-
39、sided ones) in the feeder. Setthe selector to make three copies per original. Set the sorter tosort and collate the three sets of copies. Repeat steps 9.5.3 to9.5.4. Report this result as the simplex rate with three copies.(To make this measurement the copier must be equipped witha feeder and sorter
40、, with a feeder and offset stacking tray, orwith a recycling stack feeder. If the test copier is not soequipped, go to 9.6 below.)9.5.5 Set the copier paper feed as described in 9.3.1. Placethe first set of originals (the single-sided ones) in the feeder. Setthe selector to make five copies per orig
41、inal. Set the sorter tosort and collate the five sets of copies. Repeat steps 9.5.3 and9.5.4. Report this result as the simplex rate with five copies.9.6 Machine Copy Rate with Duplexing:9.6.1 Measure the copy rate with duplexing. This is thenumber of copies per minute that the copier can make for a
42、given number of originals with text on one or both sides of theoriginals and the copying being done to one or both sides of thecopies. There are three types of duplexing: 1 to 2, 2 to 1 and 2to 2. Because the copy rate will depend on the load and theduplexing mode, each duplexing mode will be tested
43、 withoutputs of one, three and five sets from ten originals.9.6.1.1 One to two duplexing is the copying of materialfrom originals with information on one side of the original tocopies with information on both sides of the copies. Thereshould be a one to one correspondence between originals andcopies
44、 in pages but there should be fewer sheets of copiedpaper.9.6.1.2 Two to one duplexing is the copying of materialfrom originals with information on both sides of the original tocopies with information on one side of the copies. There shouldbe a one to one correspondence between originals and copies
45、inpages but there should be more sheets of copied paper thanoriginal sheets of paper.9.6.1.3 Two to two duplexing is the copying of materialfrom originals with information on both sides of the original tocopies with information on both sides of the copies. Thereshould be a one to one correspondence
46、between originals andcopies on both sheets of paper and pages.9.6.2 To measure the 1 to 2 duplexing copy rate set thecopier paper feed as described in 9.3.1. Place the one-sided setof originals in the feeder. Set the selectors to make one copy ofthe originals in the 1 to 2 duplexing mode. (To make t
47、hismeasurement the copier must be configured to do 1 to 2duplexing. If the test copier is not so designed, go to 9.6.6below.)9.6.3 Simultaneously start the stopwatch and press the startbutton on the copier. Stop the stopwatch when the “ready forcopying” prompt or indicator comes on. (If there is no
48、readyindicator per se, stop the watch when the last copy drops intothe out tray, when the last original is ejected from the feeder, orother appropriate time.) Check the printed copies to see that allcopies were properly made, are properly sorted and are of goodquality. If there is a discrepancy, a b
49、lank side is found, or a jamoccurs, make note of this and then redo the test. The latterresult will be considered valid.9.6.4 To measure the 1 to 2 duplexing copy rate for threesets, set the copier paper feed as described in 9.3.1. Place theone-sided set of originals in the feeder. Set the selectors tomake three copies of the originals in the 1 to 2 duplexing mode.Repeat steps 9.6.3 and 9.6.4. Report this result as the copy ratewith 1 to 2 duplexing and three copies.9.6.5 To measure the 1 to 2 duplexing copy rate for five sets,set the copier paper feed as described in 9.3.1. Pl
