1、Designation:F240604(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.A numb
2、er 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 printer for print
3、ing an 8 by 10 in.image area on a lettersize page at 50 6 0.5%fill of each individual color.Thispractice requires an accurate gram scale to weigh the solid inksticks and the printed pages,a personal computer able to printa 50 6 0.5%fill of each color,as well as a test printer.1.2 This standard does
4、not purport to address all of thesafety concerns,if any,associated with its use.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.Terminology2.1 Definitions of Terms Spe
5、cific 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 inkstick is set up to determin
6、e 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 amount ofink used to print
7、 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 practice.4.Significance and U
8、se4.1 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 coverages(Ce)from the calculatedyiel
9、d(Y)using the following formula(see Table 1):50%Coverage/Ce5 Y/YeorYe5 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 the printer mayrequire the use of a clea
10、ning 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 weighed.Every effortshould be made to run the t
11、est 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 purged from the system.6.Reagents and Materials6
12、.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 Agram scale with 0.1 g readability,6000 g capacity,0
13、.1g repeatability,6 0.2 g linearity and 8.5 by 11 in.platen areais required.7.Hazards7.1 There exist no unusual hazards related to this practice.8.Procedure8.1 Testing will be done with one color ink stick at a time.8.2 Select and weigh the solid ink stick to be tested.Weight=Wis.1This practice is u
