3.1

ADF speed

rate at which a device scans documents using an automatic document feeder (ADF) to demonstrate the productivity of the ADF and is represented with suffix A

3.2

duplex

duplex scanning

use of a scanning device with the scanning being done for both sides of a sheet

Note 1 to entry: An equivalent term is “double sided scanning”.

3.3

scEFTP

effective throughput

rate at which a device scans pages measured from the initiation of the job through the full ejection of the last page of the scanning sets or through the complete creation of the file on the shared network folder or PC after the transfer of the last page of the last test set (3.16)

Note 1 to entry: “sc” denotes that the measurement is taken on the scanner.

Note 2 to entry: There are suffixes such as “_1setA”, “_30secF” or “_30secP”. Each suffix is used to classify tests such as “1 set test” or “1 set + 30 second test” of the objects of tests for “ADF productivity measurement” (using suffix A), “scan to network folder productivity measurement”(using suffix F) or “scan to pc file productivity measurement” (using suffix P) test respectively.

Note 3 to entry:scEFTP is expressed in images per minute (ipm); it can be affected by scan time, digital processing time, maintenance and the run time of the test.

Note 4 to entry: A different term (“EFTP; effective throughput” for digital copying machines) is defined in ISO/IEC 24735.

Note 5 to entry: As for scEFTP_30secF, measurement parameters involving the measurement of file transmission to a network folder are dependent on other factors like the computer and network configuration and represent relative values and not absolute values.

Note 6 to entry: As for scEFTP_30secP, measurement parameters involving the measurement of file transmission to a file are dependent on other factors like the computer, IO connection, IO speed and represent relative values and not absolute values.

3.4

scESAT

estimated saturated throughput

rate at which a device scans pages measured from full ejection of the last page of the first test set (3.16) from ADF through the full ejection of the last page of the last test set (using suffix A)

Note 1 to entry: “sc” denotes that the measurement is taken on the scanner.

Note 2 to entry: There are suffixes such as “_1setA”, “_30secF” or “_30secP”. Each suffix is used to classify tests such as “1 set test” or “1 set + 30 second test” of the objects of tests for “ADF productivity measurement” (using suffix A), “scan to network folder productivity measurement”(using suffix F) or “scan to pc file productivity measurement” (using suffix P) test respectively. There is no measurement for “scan to network folder productivity measurement” or “scan to pc file productivity measurement” of scESAT, scESAT_30secF and scESAT_30secP defined, therefore scESAT_1setA, scESAT_1setF, and scESAT_1setP are not used as classifications.

Note 3 to entry:scESAT is expressed in images per minute (ipm).

3.5

scFPE

first page eject

number of seconds between the initiation of the job to full ejection of the first page of the first test set (3.16) from the ADF

3.6

scFSOT

first set out time

number of seconds between the initiation of the job to full ejection of the last page of the first test set (3.16) from the ADF

Note 1 to entry: There are suffixes such as “_1setA”, “_30secF” or “_30secP”. Each suffix is used to classify tests such as “1 set test” or “1 set + 30 second test” of the objects of tests for “ADF productivity measurement” (using suffix A), “scan to network folder productivity measurement”(using suffix F) or “scan to pc file productivity measurement” (using suffix P) test respectively .

3.7

full detailed report

presentation of information including machine setup, summary and full measured test results

Note 1 to entry: An example of the full detailed report is shown in Annex B.

3.8

full report

presentation of results including the scFSOT (3.6) , scESAT (3.4) , and scEFTP (3.3) values in the performance test (3.10) as well as the calculated averages for each value

3.9

network folder speed

rate at which a device scans and stores the scanned image file in the network folder to demonstrate the overall productivity of the device when scanning documents

Note 1 to entry: Suffix"_F" means"scan to network folder productivity measurement".

3.10

performance test

test used to evaluate productivity by providing scFSOT (3.6) , scESAT (3.4) , and scEFTP (3.3) without using any special feature or mode, and includes both the simplex scanning (3.12) mode and the duplex scanning (3.2) mode if available

3.11

scLSOT

scLSOT _Nsets

scanning last set out time

number of seconds between the initiation of the job to full ejection of the last page of the last test set (3.16) from ADF

Note 1 to entry: There are suffixes such as “_1setA”, “_30secF” or “_30secP”. Each suffix is used to classify tests such as “1 set test” or “1 set + 30 second test” of the objects of tests for “ADF productivity measurement” (using suffix A), “scan to network folder productivity measurement”(using suffix F) or “scan to pc file productivity measurement” (using suffix P) test respectively.

3.12

simplex

simplex scanning

use of a scanning device when only a single side of a sheet is scanned

Note 1 to entry: An equivalent term is “single sided scanning”.

3.13

summary report

presentation of results including the average overall scEFTP (3.3) in the performance test (3.10) for the scanning device default base line performance

3.14

test file

digital file used for creating test targets (3.17)

3.15

test run

operation of scanning all pages of targets from a test file (3.14) , in a particular system configuration, with a particular set and page count

Note 1 to entry: Scan times are recorded for each test run.

3.16

test set

all of the pages of targets from a test file (3.14)

3.17

test target

hardcopy document used for testing per the test method, and created from test file (3.14)

Note 1 to entry: An equivalent term is “test chart”.

3.18

time measurement

number of seconds measured by a timing device (stopwatch or other device) or by reading time display on the PC clock

Note 1 to entry: Suffixes such as"_sw" and"_PC" are used to show which time measurement is done; by timing device (stopwatch or other device) or by reading time display on the PC clock.
