1、Designation: F2406 04 (Reapproved 2012)Standard Practice forDetermining Yield of Solid Ink Sticks1This standard is issued under the fixed designation F2406; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.
2、 A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers a procedure to determine the yieldin number of pages per solid ink stick used in a solid ink/phasechange printe

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

5、initions of Terms Specific to This Standard:2.1.1 ink stick yield (Y)amount of pages that can beprinted from one ink stick.2.1.2 solid ink stickconsumable used in a hot-melt print-ing device to apply color to a page.3. Summary of Practice3.1 A solid ink/phase change printer utilizing a solid inkstic
6、k is set up to determine yield in number of pages per solidink stick used in a solid ink/phase change printer. A test pagewith 50 6 0.5 % print output of each color for control is used.The solid ink stick is weighed.Aspecified number of prints arecreated on the printer using the solid ink stick. The
7、 amount ofink used to print the specified number of sheets is calculated.The results can be used to estimate the total page yield per solidink stick at various percent coverages. A comparison can bemade between the solid ink stick used for the control and anyother solid ink stick tested using this p
8、ractice.4. Significance and Use4.1 This practice can be used for the evaluation of OEM andcompatible ink sticks.4.2 This practice is suitable for research and developmentand quality acceptance evaluations.4.3 This practice is suitable to extrapolate ink yield (Ye)ofeach color at other percent covera
9、ges (Ce) from the calculatedyield (Y) using the following formula (see Table 1):50% Coverage/Ce 5 Y/YeorYe 5 YCe!/50% Coverage5. Interferences5.1 This practice does not consider the effects of thecleaning mechanism and its use of ink in lowering the effectiveyield of the solid ink. During normal use
10、 the printer mayrequire the use of a cleaning cycle which will reduce theeffective yield of the solid ink stick. During this test the use ofthe cleaning cycle during the printing should be avoided.5.2 Changes in humidity and temperature will have an effecton the measurements of the paper being weigh
11、ed. Every effortshould be made to run the test in a controlled environment.5.3 When changing ink sticks from one test of the samecolor to another test of the same color, at least three times theamount of ink normally stored in the reservoir should be runthrough the printer to insure that ink is purg

Reagents and Materials6.1 Sufficient quantities of same lot paper, ink and otherprinter specific consumables should be available for consis-tency.6.2 A reference target that can be verified to print at 50 60.5 % coverage on an 8 by 10 in. image area on a letter sizepage.6.3 Agr

17、sheets each of conditioned paperusing the 50 % test target alternatively with ten sets of 100empty sheets of the same stock and lot. This should be doneusing optional high capacity trays if available to allow forcontinued printer operation.8.7 Measure the weight of the 10 sets of 100 pagesindividual
